erwin Data Modeler Reviews

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.

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.
