IT Central Station is now PeerSpot: Here's why

erwin Data Modeler (DM) Primary Use Case

David Jaques-Watson - PeerSpot reviewer
Senior Consultant at a tech services company with 11-50 employees

In one of the companies, we used it as an information tool. We created a logical model so that the business would know what was in the offices down to the warehouse. The current use case is also the same. We have some places for information, so we can do a logical data model for them, but, usually, it would go towards building an actual database, which also involves reverse engineering of an existing one because people don't know what's in there.

It is currently on-prem, but we still have a separate server.

The use case was normally to update data model designs for transaction processing systems and data warehouse systems. Part of our group also was doing data deployment, though I personally didn't do it. The work I did was mostly for the online transaction systems and for external file designs.

I didn't use it for data sources. I used the solution for generation of code for the target in the database. Therefore, I went from the model to the database by generating the DDL code out of erwin.

We had it on-premise. There was a local database server on SQL, then we each had a client that we install on our machines.

We have a couple of really important use cases for erwin. One of them is that we automate the pull of metadata from the repository itself, so that we have all the model metadata that we can then put into a centralized hub that we can access with other applications. Another reason we pull all the metadata out of the model is to run it through our model validation application, which telsl us if this model is healthy or not and if it meets our standards or not.

The other use case that's really important is managing the abbreviations file that erwin uses to convert logical terms into physical terms. The way that you manage it today within erwin is very manual and you'll go from a spreadsheet, make changes, and upload, et cetera-- but we've created an API application where if we take the main standard file and keep it in the database, make the changes in the database, then we have an application that goes out into the Mart file, deletes the glossary, replaces it with the table from the database. It's all automated at the push of a button. It's things that would take us days to make changes in the standard files and do updates in eight different files.

I am responsible for both a combination of documenting our existing data models and using erwin Data Modeler as a primary visual design tool to design and document data models that we implement for our production services.

My primary role is to document our databases using erwin to work with people and ensure that there is logically referential integrity from the perspective of the data models. I also generate the data definition language (DDL) changes necessary to maintain our data models and databases up to our client requirements in terms of their data, analytics, and whatever data manipulation that they want to do. I use erwin a lot.

It is either installed locally or accessed through a server, depending on where I have been. I have had either a single application license or pooled license that I would acquire when I open up erwin from a server.

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.

We are using it for a very specific use case, and it works pretty well for us. We do all of our database modeling based on this tool, and it is a repository of all data models in our business intelligence ecosystem. The logical representation of our metadata and anything that is created in a database, such as tables, is in it. 

It is an on-prem workgroup. We have a workgroup server that hosts our model.

Senior Project Manager at a tech services company with 51-200 employees

For the first 30 years of my career, I worked on many small projects. Since erwin was released, I used it to help develop projects up until about two years ago. At that time, I moved to a new company and I still use erwin in my current role.

When I moved to the new company, I recommended erwin and explained it to my colleagues and my clients. When the most recent version was released, I looked at the licensing and became familiar with its new features and benefits.

I have developed a couple of projects myself in the past two years, including one that had to do with mail, in Serbia, which was an interesting project. Another and the other to do with handling automotive equipment maintenance. One of the projects is something that I started from the beginning, whereas the other was reengineered with changes made and new features added.

I have also worked with erwin from a higher-level role. Rather than developing smaller projects, I have taken responsibility for a much larger project worth several million Euros.

erwin is deployed on individual desktops and the individual users install it or have a help desk person install it for them.

Our primary use case is for during any type of project development or maintenance and application maintenance, we go through a process of modeling our data before it gets put into the database. We interact with the application development teams to determine what their requirements are and build the data models, and then turn them into actual physical database items.

Technical Consultant at a insurance company with 1,001-5,000 employees

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.

We use the Workgroup Edition for sharing data models across the organization. The primary reason we're using the Workgroup Edition over the Standard Edition is the centralized repository of models.

Standard Edition requires individuals to determine how to share data models, whether you share them in a local LAN directory, through email, SharePoint, or Livelink. You have to come up with your own versioning scheme and your method for sharing models. With the Workgroup Edition, because it has the centralized repository with version control embedded in it, it standardizes how your organization does versioning and centralizes all the models at the same time.

We use the erwin Data Modeler tool to document conceptual, logical, and physical data design. Business data models capture the understanding of the data from a business perspective, which can then drive physical design to ensure data is represented and used correctly.

Senior Data Warehouse Architect at a financial services firm with 1,001-5,000 employees

We use erwin DM as a data modeling tool. All projects in the data warehouse area go through the erwin model first and get reviewed and get approved. That's part of the project life cycle. And then we exude the scripts out of DM into Snowflake, which is our target database. Any changes that happen after that also go through erwin and we then make a master copy of the erwin model.

Our solution architecture for projects that involve erwin DM and Snowflake is an on-prem Data Modeler desktop version, and we have a SQL database behind it and that's where the models are stored. In terms of erwin Data Modeler, Snowflake is the only database we're using.

We are not utilizing a complete round-trip from DM for Snowflake. We are only doing one side of it. We are not doing reverse-engineering. We only go from the data model to the physical layer.

Richard Halter - PeerSpot reviewer
President at a tech services company with 51-200 employees

I was part of a standards organization and we built a data model that is a standard data model for use in retail. That data model is now been released in version 7.3 and it is implemented all over the world. We don't implement the model, we've built the logical model and then the companies build their own physical model from there. 

erwin is a retail data model, which means that it handles the operational side of retail, which means there are somewhere around 8,000 attributes in it. It has got around 10 groupings of things. We have a grouping on transactions and there are all kinds of transactions that can occur in retail. The whole customer life cycle is covered in the inventory, items, and all that. The use case is for retail operations. It's massive. There are hundreds of use cases in this.

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.

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.
