erwin Data Modeler Reviews

We use the product for data modeling. 

The solution is good for organizing the data and the scripting part is very powerful. It's easy to create technical scripts for models. 

The solution's reporting side needs to be improved. 

I have been using the solution for three years. 

The solution breaks down sometimes. 

I think the solution's cloud version is better because things become slower when the model grows bigger. 

The product's technical support is fast. 

Though the solution is not cheap, it's worth the money. 

I would rate the product a seven-point five out of ten. 

We used this solution to upload and document our database models from the legacy systems.

The principal feature that I liked is that the solution has a very graphic interface.

I think the interface sometimes looks old-fashioned when compared to other solutions, so maybe that can be improved. 

Also, I would like the solution to be more user-friendly to deploy.

After those initial problems, the solution became stable.

The solution only works with one server and one database, so I don't think it's scalable enough.

The solution has a good support center. They provide responses quickly, in about a day. 

The solution was a little hard to set up. We had to request help from our provider because we had some technical problems with getting the solution to work. There were some problems with configuration, and it took about three months to get the solution working.

My advice to those considering this solution would be that they should first evaluate what they need. I suggest they maybe do a POC to evaluate their use cases and then work at finding a solution, and run all the necessary tests before starting to work with the solution.

I would rate this solution as a seven out of ten.

We are a reseller and erwin Data Modeler is one of the products that we provide to our clients.

This product is the strongest data modeler on the market.

It has centralized storage so that a data model can be shared by different teams.

The erwin Data Modeler is quite complex to use. However, if you are using the desktop version then you can use a small subset of the features and still get along very well. In this regard, it is similar to Microsoft Excel or Microsoft Word.

We have been working with the erwin Data Modeler for between two and three years.

erwin DM is very robust.

We are satisfied with the scalability.

The technical support is satisfactory.

Price-wise, erwin Data Modeler is okay. You can purchase a single license and it is not very expensive.

The erwin data model is a very good product. It has more than 20 years of history and has improved since it was acquired by erwin a few years ago. It was originally a desktop application and since erwin acquired it, it has been converted into a web application. They have been working hard to improve it and it is difficult to say what can be done to improve it further.

Overall, it has been quite good.

I would rate this solution an eight out of ten.

We use it in order to create models, do some reverse engineering in the case of existing databases, and for comparing models, e.g., what is in the design vs reality.

It provides us a visual of the database, which helps me with the complexity of the models. We can know if someone made changes to anything, which is very important from a development perspective. It helps us maintain control of the work.

We had some data integration projects, where we needed to integrate it for about 100 databases. Doing that manually is crazy; we can't do that. With erwin, it was much easier to identify which tables and columns could be used for the integration. That means a lot in terms of time and effort as well as my image to the customer, because they can see that we are providing value in a very short time.

The solution's code generation ensures accurate engineering of data sources. This accuracy affects our development time a lot. It is very easy to go into the graphical model to change something, e.g., generate scripts. It now takes minutes (less than an hour).

The ability to collaborate between different members across the organization is the most valuable feature. It gives us the ability to work on the same model, regardless of where we are physically.

I like the accuracy. It is very precise.

I am not so happy with its speed. Sometimes, it can have problems with connections.

erwin's automation of reusable design rules and standards is good, but it could be better.

About 30 years.

It is pretty good. I haven't had any problems with crashes, etc.

We have a consultant who is responsible for the maintenance.

The solution's scalability is good. However, there isn't a clear explanation of how to go from 10 to 20 users, which is something that customers ask us.

In my company, there are currently five data managers who use erwin.

I like their technical support. They try very hard to solve the problem.

They are not supporting old versions of some databases anymore, so I don't always have the tools that I need. I would like them to keep the support for the older versions.

The standard edition is quite straightforward to set up. It is just clicking, "Next, Next, Next." This takes less than an hour to set up.

It gets complicated when we set up the group edition. We need to start a database. Sometimes, erwin support is needed for the setup. The setup for the group edition can take two days to a week, depending on the database.

We also sell erwin to some of our customers. Usually, we create some sort of implementation steps to ensure that it will work.

We have seen ROI in terms of time, e.g., consulting time and the ability to answer customers faster. This has improved the image of the company.

The solution’s ability to generate database code from a model for a wide array of data sources cuts development time from two weeks to one day or even hours. This is one of the features that I like.

The price should be lower in order to be on the same level as its competitors.

I have worked with Toad, Sparx, and the free version of Oracle Data Modeler. erwin DM's competitors are cheaper, but the look and feel of erwin is more user-friendly, professional, mature, and enterprise level.

I recommend using erwin Data Modeler. You should have a good business case to convince the finance team, as the price is high for Latin America.

I would rate this solution as nine out of 10.

My previous employer's use case was around data warehousing. We used it to house our models and data dictionaries. We didn't do anything with BPM, etc. The company that I left prior to coming to my current company had just bought erwin EDGE. Therefore, I was helping to see how we could leverage the integration between erwin Mapping Manager and erwin Data Modeler, so we could forward engineer our models and source port mappings, then mapping our data dictionary into our business definitions.

We didn't use it to capture our sources. It was more target specific. We would just model and forward engineer our targets, then we used DM to manage source targets in Excel. Only when the company first got erwin EDGE did we start to look at leveraging erwin Mapping Manager to manage source targets, but that was still a POC. 

As far as early DM source specific, we didn't do anything with that. It was always targeted. 

It improved the way we were able to manage our models. I come from a corporate background, working for some big banks. We had a team of about 10 architects who were spread out, but we were able to collaborate very well with the tool.

It was a good way to socialize the data warehouse model within our own team and to our end users. 

It helped manage some of the data dictionary stuff, which we could extract out to end users. It provided a repository of the data warehouse models, centralizing them. It also was able to manage the metadata and have the dictionary all within one place, socializing that out from our repository as well.

Typically, for an engineer designing and producing the DDL out of erwin, we will execute it into the database, then they have a target that they can start coding towards. 

• Being able to manage the domains.
• Ability to standardize our data types and some common attributes, which was pretty powerful. 
• The Bulk Editor: I could extract the metadata into Excel (or something) and be able to make some mass changes, then upload it back.

We use the macros with naming standards patterns, domains, datatypes, and some common attributes. As far as other automations, a feature of the Bulk Editor is mass updates. When it sees something is nonstandard or inaccurate, it will export the better data out. Then, I can easily see which entities and attributes are not inline or standard. I can easily make changes to what was uploaded to the Bulk Editor. When taking on a new project, it can save you about a half a day on a big project across an entire team.

The Bulk Editor needs improvement. If you had something that was a local model to your local machine, you could connect to the API, then it would write directly into the repository. However, when you have something that is on the centralized server, that functionality did not work. Then, you had to export out to a CSV and upload up to the repository. It would have been nice to be able to do the direct API without having that whole download and upload thing. Maybe I didn't figure it out, but I'm pretty sure that didn't work when it was a model that sat on a centralized repository.

I have been using erwin since about 2010. I used it last about a year ago at my previous employer. My current employer does not have it.

We only had one guy who would keep up with it. Outside of the server, as far as adding and removing users and doing an upgrade which I would help with sometimes, there were typically only two people on our side maintaining it.

There are about 10 users in our organization.

There were a couple of little things that you had to remember to do. We ran into a couple of issues more than once when we did an upgrade or install. It wasn't anything major, but It was something that you really had to remember how you have to do it. I

t takes probably a few hours If you do everything correctly, then everything is ready to go.

There were two people from our side who deployed it, a DBA and myself. 

We didn't go directly through erwin to purchase the solution. We used Sandhill Consulting, who provided someone for the setup. We had used them since purchasing erwin. They used to put on workshops, tips and tricks, etc. They're pretty good.

Once you start to get into using all the features, it is definitely worth the cost.

With erwin Mapping Manager, which I have PoC'd a few times, it was something that I'd always get to produce ETL code. I have also used WhereScape for several years as well, and that type of functionality is very useful when producing ETLs from your model. It provides a lot of saving. When you're not dealing with something extremely complex, but just has a lot of repeatable type stuff, then you get a pretty standard, robust model. That's a huge saving to be able to do that with ETL code.

The ability to compare and synchronize data sources with data models in terms of accuracy and speed for keeping them in sync is pretty powerful. However, I have never actually used the models as something that associates source. It is something I would be interested in trying to learn how to use and get involved with that type of feature. It would be nice to be able to have everything tied in from start to finish.

I am now working with cloud and Snowflake. Therefore, I definitely see some very good use cases and benefits for modeling the cloud with erwin. For example, there is so much more erwin can offer for doing something automated with SqlDBM. 

I would rate this solution as an eight out of 10.

When I work from home, my use case for erwin is for when I get a request for a database upgrade. Usually, the request comes in with a whole bunch of tables and names so I'll go into the DM and I'll start building out what they're asking for. Once we actually get them to be able to view it and understand it, then we'll go back and forth with the developers and the requesters to make sure that it's exactly what they're looking for. We'll spend a few days making sure everything looks correct. Once that's finished, I'll send it out. 

Unfortunately, I can't do a PDF straight from erwin so I'll copy everything into Word and then save my Word as a PDF. With that PDF, I'll be able to send it off to all the stakeholders, not just the developers and the requesters, so that everybody can see it, even the ones that don't have erwin itself.

My office use case is pretty much the same, except with the office, we add in Model Mart. We have our entire network, all the databases, and everything in Model Mart and it's over 1,500 different tables, relationships, attributes, and things like that. It's a really large model. Then, we break down that model into individual subject areas and we work through those. We go back to any new requests, we'll build them in Data Modeler and we'll go back and forth with the requesters, making sure everything looks like what they're expecting it to. They'll usually just send us either a spreadsheet of names and data types and then we build from there.

erwin brings data to life. We're currently working with a requester at that moment, who provided us with a spreadsheet of their ideas of tables and attributes with the metadata associated with each. Then they provided us a rudimentary diagram with tables and keys. I was able to put it into erwin along with the metadata that they were asking for, and it really brought questions to life. The people said, "We didn't realize the relationships were going to bring in these extra keys." And they didn't realize there were a lot of extra pieces coming in as well. Once we did that, we were able to show them exactly what they were asking for and it brought much more conversation between us.

We don't use DM's modeling support for Snowflake cloud yet. I am interested in cloud technology and I just came across that support that erwin has. It made me even more interested in cloud technology. 

Its ability to generate database code from a model for a wide array of data helps another office in my company that uses it quite a bit. 

The automatic build to the physical is a really nice feature. I like the fact that it will bring the keys down from one table to the next, from a parent to child table. Those two things make erwin a very easy to use product. 

It's a safeguard for me because I'm always concerned that somebody is free handing it and will forget a key coming from the parent. The migrating keys are a great feature. Identifying relationships, non-identifying relationships, and being visually right there to understand the differences are great features.

erwin is key to being able to visually understand whatever the customer is requesting. They'll give you words on a paper, but once they can actually view it as a picture, it really comes to life. The data comes to life to where they understand exactly what they're asking for.

I'd really like to see the PDF function become available. It would make my life much easier than what it is at the moment because whenever I need to collaborate with people that do not have erwin, I have to go through the wonkiness of going to Word and then save it from Word into PDF. There's a lot of differences between erwin 4.4 and 2020. It's a learning curve for me. It could be easier to use, but it's not a Windows/Microsoft type of application. It's close to it but it's also not. Once I've used it enough and learned it, then I'll know where all the pieces are.

I've been a data modeler in my office for six years so I've been using erwin for six years. My office has been using erwin since the beginning of time. I'm not exactly sure when they started using it, but the office has been around for 20 years so they've probably been using it since erwin started.

It's on our secret network and I believe they've been going back and forth quite a bit with erwin's tech teams as far as getting it to work because I think our workstations are virtual workstations and there were some issues with the licensing and the license server. I've been watching that from the peripherals but not really getting in the weeds with them. I'm not sure exactly what they're doing.

I've only had it crash on me once. I can't remember what I was doing and when or how it crashed. It was one of those inconvenient times and so I started again. I don't think an auto-save was done. That happened three weeks ago.

I use it at home every day and there are days where I've used it almost an entire eight hour day. I'm using it quite heavily right now.

The only time I've had to use erwin technical support was when I requested an extension on my trial license. They were really quick and good about it.

The initial setup was straightforward. I was able to install it at home without a problem whatsoever. Within a few seconds, I was able to figure out how to start building a table. I had no problems whatsoever. I think my colleagues who are going into work might have a little bit of a different answer because of issues with service, license keys, and what have you.

The deployment took five to ten minutes. There wasn't a lot of customization necessary. It's been a couple of months now since I've started doing it. I can see from the tab that I'm on that I need to just click on the table, click the area there, and start building tables. I've also had experience with it, so that makes it easier as well. It's intuitive.

At the office, there's quite a bit of strategy on how they needed to deploy it and how they needed to have it totally set up in the virtual world. They were upgrading from an older version.

At our office, we have two or three different people that were truly involved, but we did have one main person doing the going back and forth with erwin as far as getting help and setting it up. That took a couple of weeks, if not longer, to actually get it set up working correctly.

We bought a total of 10 licenses, although I'm not so sure. It's less than 25.

I would definitely say that it's a time saver once you learn how to use the application. It takes a little while to teach people how to use it just like with any other application, but as far as time-saving afterward, it's invaluable. As far as taking the time to truly show a person the end result, we can show them exactly what we're talking about and that's really invaluable. I'm sure the deployment would say the same thing as far as being able to build the database off of it.

The accuracy and speed in transforming complex designs into well-aligned data sources make the cost of the tool worth it. At the same time, I don't do that.

It saves us a couple of hours of actually trying to build something. It's not something that my office does every day. However, when we do it, I could not imagine building tables or building a diagram from any other tools that are currently in the office. It's impossible to do it from PowerPoint or Word. 

I don't think that the pricing for my office is horrible. However, from my home, there's absolutely no way I could afford erwin on my own as far as doing my own work.

There have been discussions between my office and the actual company that I work for and trying to decide on who would actually pay the bill. I'm the person stuck in the middle saying that I can't do my work here and luckily, I've been able to get one or two extensions on my free trial license from erwin. However, I'm afraid that I won't be able to get my company to pay for it and fairly soon the trial license will end up expiring on me.

I decided to build physical only but later on that kind of bit me and so I will start building logical first and then the physical. It would be nice to be able to build out my own set of tables and maybe a Model Mart type of situation but I don't see me being able to afford a copy at home for myself. I won't be able to continue keeping a trial copy forever and until COVID is over.

When COVID started, I did start looking at home versions of other freeware because I had time to actually do some research. I found that most of the freeware wasn't really free. It was also still kind of clunky and one of the applications that I was using didn't automatically bring the keys down and for me, that was a killer right there. I would not suggest the application to anyone. From the trial copies of the other applications they use, I think that's where erwin really comes up ahead, above the other applications.

The biggest lesson I have learned from erwin is the old cliche, that a picture is worth a thousand words. It is truly erwin in itself. When a person asks for a set of tables and they actually see that diagram visually, it really assists in any meeting that you will have. It is key to any meeting you have.

I would rate Data Modeler an eight out of ten. The reason for this rating is because I did a couple of dumb attributes and it took me forever to find how to truly delete it. It was a parent-child relationship and I deleted the parent and did not answer the question from the next box that popped up correctly. So I had an attribute hanging out in a table and it took me forever to find the dangling relationships. Because of that, I knocked it down a rating because it did take me a long time to find that.

I'm quite happy with the modeling tool. It does just about everything that I need it to do. I can't really think of what it doesn't do that I would need other than the PDF. I'm really happy with it.

I'm an application developer with a fair amount of database background so I mostly use the tool to do physical modeling to support our application development. I'm a firm believer in not just adding columns to a table but to actually think about it, put together an Erwin model, and look at the relationships. I used to like to generate the model and generate changes all through the tool but being honest, one of my biggest frustrations with Erwin is that it's very difficult to forward engineer and keep things in sync. It used to be so easy and now it's very difficult. It's very frustrating to use this tool for that.

We use it for data modeling but they also do a lot of logical modeling and architecture, and we also use the naming standards capability to force corporate standards across the models.

It has improved my organization because using a data modeling tool is forcing us to come up with better models.

Its code generation ensures accurate engineering of data sources. It should generate correct code, so I can't say it cuts development time just because it's doing what it's supposed to be doing correctly.

I think the ability to depict the model in a graphical fashion, think about it, and keep things consistent is what's valuable about it. It's too easy when you're using other methods to not have naming consistent standards and column consistent definitions, et cetera.

This isn't specific to Erwin, it's specific to any data modeling tool but we also like:

• The ability to graphically depict how the relationships occur and the relationship lines.
• The fact that it migrates your foreign keys for you.
• The general principles of what a data modeling tool does. 

Erwin does a lot of things well. It's just very frustrating in some areas that really should not be frustrating.

The people who don't use a data modeling tool but rather use spreadsheets or wing it typically have pretty poor data models. If you use a data modeling tool, the graphical nature of the data modeling tool forces you to think about relationships. It forces you to ask questions that you wouldn't ask if you were just creating tables and doing it off the top of your head. That's number one, in my opinion, from my own experience. The number one benefit of using a tool like Erwin, is that visual representation forces you to come up with a better model.

Its ability to generate database code from a model for a wide array of data sources is useful but we're 99% SQL Server, so the fact that it generates 60 other databases doesn't really help me too much. It doesn't support Postgres or Redshift which are the two other systems that we're using. 

I find the UI very clunky and very difficult to use. The whole workflow of adding columns to a table could be so much easier. I get frustrated using it. Resizing dialog boxes, changing fonts, printing, scrolling around in the UI, etc is very clunky.

I've tried other tools. I've tried to get off of Erwin a few times. I always come back to it because every other tool has its own set of problems, and it seems like if I have to pick my poison, I stay with Erwin. But so many things that are clunky with it. 

My biggest frustrations with the product is forward engineering and keeping things in sync. A lot of times I need to change a column definition and all I want to do forward engineer it over to the database, it used to be so easy to do that, way back in the early days with Erwin before CA bought it, and now it's almost impossible. It's very frustrating to do. I've spoken to Erwin about this in the past, and I can understand why they're doing some of the things they're doing, but I'm more of a casual user than a power user, and for me, it's so clunky. It's so much easier using Embarcadero to forward engineer changes to a database than it is using Erwin.

This product has been on the market for years and I'm amazed at some of the quirky things that I still have to deal with in this product. I wish rather than adding new features, Erwin would fix some of these usability issues.

I have been using erwin Data Modeler for around ten years before it was owned by CA.

Other than the bugs, it doesn't crash on me, so I guess the stability is good. 

We have somewhere around 20 uses. I use it as a developer and the data architects use it as well. 

We use the Mart model, we break them out into areas, and there are many models in each area. So we have around a couple hundred models.

I haven't used their support in quite a while, so I'll say neutral.

We previously used Toad and Embarcadero.

I've been using Erwin since it first came out, a long time ago. Back then it was a lot simpler to use and it was just so much easier. I think they tried to make it do everything for everybody and now it's very difficult to do some of the simplest tasks. It's very frustrating, and there are a lot of issues.

The forward engineering frustration I experience with Erwin is a thousand times easier in Embarcadero. If I want to just make a quick change to a column and forward engineer it to my database, it's a lot easier in other tools.

Some of the other tools were a lot better in the ease of use and stability of the UI but they also had their share of problems that are deal-breakers. For example, models won't print on one page.  I keep coming back to Erwin. It was the lesser of the two evils. No product is perfect but I think Erwin tries to be everything to everybody, and sometimes when you do that, it's no good to anybody.

I don't use all the features, it's nice that they're there, but I wish the stuff that I did use was better usability-tested. 

I was not involved in the installation of this particular version. When we first started using erwin, we used to install it on our local machines, but now we're using the Mart model and it's installed on servers, so we have a group that maintains it. For years and years, it used to be that we all just installed it on our local machines and ran it that way. 

It's a licensing thing. We have a concurrent license so by having it on a server, it's in one place, which is nice. That way, everyone's running the same version. Then, because we have concurrent licensing, if you have 30 people that need to use it, but people like me only use it once in a while, you don't have to buy me an expensive, dedicated license, so it's a lot cheaper to have a concurrent license for our company.

It's not necessarily erwin-specific, but by using a data modeling tool, it forces a better product, better application development, and better applications at our company. Using a tool like that is a must-have. 

I like the concurrent licensing. That's phenomenal. I think that was a big win for us.

Sometimes you have an initial idea for a data model and when you try to design it in Erwin you realize that you were wrong in how you approached it. Erwin enforces consistency and accuracy. Quite often I learn something by looking at the generated code. It's not like I create table statements all day long. I don't do that generally. So when I use the tool, it generates the correct code in scripts for me which we will then hand off to the DBAs who run them. 

I would rate it a six out of ten. It's frustrating. It could be so much better. 

The problem is mostly usability. It has little quirks about the way the screen refreshes, things move around, and the workflow when you're creating columns and tables could be so much better. 

I have a love-hate relationship. I've used this product for years. I've actually gone to training on it at Erwin, so I know what I'm doing with it. I wish they would make it easier to use. I would think if Microsoft bought it, this would be a totally different product.

Interestingly enough, Microsoft has tried to come out with data modeling tools a few times, and they are all bad. They're basically toys. You can't use them for anything real, which is surprising to me. You would have thought that they would have had a tool that could compete.

There are only a couple of big players out there that Erwin competes with. I looked at just about all of them, and I keep coming back to Erwin, but I hate it nonetheless. There's nothing better. There are certain tools that are better in certain areas but far worse in others, and so you pick your poison.

We use it for our conceptual business-data model, for logical data modeling, and to generate physical database schemas. We also create dimensional modeling models.

One of the ways Data Modeler has benefited our company is that it gives us the ability to engage with the business alongside IT, because it's friendly. It has friendly views that we can use when we meet with them. They can follow them and understand them. That increases the quality and accuracy of our IT solutions.

The solution's ability to generate database code from a model for a wide array of data sources helps cut development time. We generate all the DDL for our hub through a modeling exercise and generate the alter statements and maintenance through the erwin modeling tool. I would estimate that reduces development time by 30 to 40 percent because it's so accurate. We don't have to go back in. It takes care of the naming standards and the data types. And because we use OData, we generate our service calls off of those schemas too. So that's also more accurate because it uses what we've created from the model all the way through to a service call with OData.

I find the logical data modeling very useful because we're building out a lot of our integration architecture. The logical is specific to my role, since I do conceptual/logical, but I partner with a team that does the physical. And we absolutely see value in the physical, because we deploy databases for some of those solutions.

I would rate erwin's visual data models very highly for helping to overcome data source complexity. We have divided our data into subject areas for the company, and we do a logical data model for every one of those subject areas. We work directly with business data stewards. Because the logical and the conceptual are so easy to look at, the business side can be very engaged and collaborate on those. That adds a lot of value because they're then governing the solutions that we implement in our architecture.

We definitely use the solution's ability to compare and synchronize data sources with data models. We have a data hub that we've built to integrate our data. We're able to look at the data model from the source system, the abstracted model we do for the hub, and we can use erwin to reverse-engineer a model and compare them. We also use these abilities for the lifecycle of the hub. If we make a change, we can run a comparison report and file it with the release notes.

I would like to see improved reporting and, potentially, dashboards built on top of that. Right now, it's a little manual. More automated reporting and dashboard views would help because currently you have to push things out to a spreadsheet, or to HTML, and there aren't many other options that I know of. I would like to be able to produce graphs and additional things right in the tool, instead of having to export the data somewhere else. And that should work in an intuitive way which doesn't require so much of my time or my exporting things to a spreadsheet to make the reporting work.

I've used the erwin Data Modeling tool since about 1990. I work more with the Standard Edition, 64-bit.

It's stable. This specific tool has been around a long time and it has matured. We don't encounter many defects and, when we do, a ticket is typically taken care of within a couple of days.

We're using standalone versions, so we don't need to scale much. In the Workgroup Edition we've got it on a server and we have concurrent licensing, and we've had no issues with performance. It can definitely handle multiple users when we need it to.

At any time we have six to 10 people using the Workgroup Edition. They are logical data modelers and DBAs.

We've already increased the number of people using it and we've likely topped-out for a while, but we did double it each year over the past three years. We added more licenses and more people during that time. It has probably evolved as far as it's going to for our company because we don't have more people in those roles. We've met our objectives in terms of how much we need.

I would rate erwin's technical support at seven out of 10. One of the reasons is that it's inconsistent. Sometimes we get responses quickly, and sometimes it takes a couple of days. But it's mostly good. It's online, so that's helpful. But we've had to follow up on tickets that we just weren't hearing a status on from them.

They publish good forums so you can see if somebody else is having a given problem and that's helpful. That way you know it's not just you.

We did not have a previous solution.

I've brought this tool into four different companies, when I came to each as a data architect. So I was always involved early on in establishing the tool and the usage guidelines. The setup process is pretty straightforward, and it has improved over the years.

To install or make updates takes an hour, maybe.

A lot of the implementation strategy for Data Modeler in my current company was the starting of a data governance and data architecture program. Three years ago, those concepts were brand-new to this company. We got the tool as part of the new program.

For deployment and maintenance of the solution we need one to two people. Once it's installed, it's very low maintenance.

We did it ourselves, because we have experience.

We're very happy with the return on investment. It has probably exceeded the expectations of some, just because the program is new and they hadn't seen tools before. So everyone is really happy with it.

erwin's automation of reusable design rules and standards, especially compared to those of basic drawing tools, has been part of our high ROI. We're using a tool that we keep building upon, and we are also able to report on it and generate code from it. So it has drastically improved what was a manual process for doing those same things. That's one of the main reasons we got it.

We pay maintenance on a yearly basis, and it's a low cost. There are no additional costs or transactional fees.

The accuracy and speed of the solution in transforming complex designs into well-aligned data sources make the cost of the tool worth it.

We looked at a couple of solutions. Embarcadero was one of them.

erwin can definitely handle more DBMSs and formats. It's not just SQL. It has a long list of interfaces with Oracle and SQL Server and XSD formats. That's a very rich set of interfaces. It also does both reverse- and forward-engineering well, through a physical and logical data model. And one of the other things is that it has dimensional modeling. We wanted to use it for our data warehouse and BI, and I don't believe Embarcadero had that capability at the time. Most tools don't have all of that, so erwin was more complete. erwin also has several choices for notation and we specifically wanted to use IDEF notation. erwin is very strong in that.

The con for erwin is the reporting, compared to other tools. The interface and reporting could be improved.

My advice would depend on how you're going to be using it. I would definitely advise that, at a minimum, you maintain logical and physical views of the data. That's one of the strengths of the tool. Also, while this might sound like a minor thing, it's important to create standard templates — Erwin is good at that — and you can customize them. You can create a standard template so that your models have the same look and feel. And then, anyone using the tool is using the same font and the same general layout. erwin's very good at helping enforce that. You should do that early on so that you don't have to redo anything later to make things look more cohesive.

Another feature of erwin is that it can help you enforce your naming standards. It has little modules that you can set up and, as you're building the data model, it's ensuring that they conform to the naming standards that you've developed. I think that's something that some people don't realize is there and don't take advantage of.

The biggest lesson I have learned from using this solution faces in two directions. One is the ability to engage the business to participate in the modeling. The second is that the forward-engineering and automation of the technical solution make it more seamless all the way through. We can meet with the business, we can model, and then we can generate a solution in a database, or a service, and this tool is our primary way for interacting with those roles, and producing the actual output. It's made things more seamless.
