Erwin Data Modeler was used by our DBA and Data Architecture to design new data models and document the existing physical databases by reverse engineering them.
  • Creation of logical data models
  • Reverse engineering
  • Excellent communication tool in conversations with Developers and BAs
  • As a company, Erwin provides lots of tutorials and how-tos.
  • The main con I can think of is cost.
  • It takes time to setup and learn which is an adoption barrier.
  • Modeling of complex environments
  • Documenting existing databases
  • Communication tool between BAs, Architects, DBAs and Developers
  • Modeling and documentation tool for developing our Data Warehouse

We currently use erwin Data Modeler on a very small scale. We use it to standardize record abbreviations and field names.
  • It is reliable in the use case we have, to rename and standardize fields accurately.
  • erwin has as very great customer service team.
  • Interface is very old seeming
  • Small text and multiple buttons makes the user interface difficult to maneuver
erwin has many capabilities that our company does not use to the full potential. We simply use it as a naming conversion tool to standardize our field names.

We are using erwin Data Modeler for initial design, development and deployment phases. We use it to design ER diagrams for our new databases or incorporate change requests into existing. We then forward engineer deployment scripts for erwin directly and deploy it to various database environments. This has helped us version control and release control in our database environments. It is also easier to discuss with functional team by presenting them with ER diagram block instead of talking to them in database language.
  • Reverse Engineering: I love the way we can import an SQL file containing schema meta data and generate ER diagram out of it. This is specifically useful if you are implementing erwin Data Modeler for an existing database.
  • Forward Engineering: We use this feature very frequently. Where we do database changes in our physical and logical data models and then generate deployment scripts for the changes made.
  • Physical vs Logical Models: I like to have my database model split into physical and logical models and at the same time still linked to each other. Any changes you make to logical model or physical model shows up in the other.
  • For large models, it gets tedious to print the diagram in a single pdf. I have to often make adjustment and if i use the fit model feature, it kind of changes the alignment of entities in my ER diagram. Erwin may let us make pdf of the model as is.
  • I have used reverse engineering using for Oracle schemas. It will be very good if it supports reverse engineering for more vendors, so i can use erwin data modeler for database conversion activities too.
If you have a database environment that gets frequent schema object change requests. erwin Data Modeler is a great tool for version control and release control. Also, it's very useful to communicate between database and application teams.

We are a big organization that supports multiple applications. We use erwin Data Modeler for database model design before it can actually make to the database.
We build ER diagrams out of requirement documents and then use these ER diagrams to discuss in meetings with functional and DBA teams. Once the design is approved, we further use erwin Data Modeler to make both logical and physical data models, include triggers and constraints in the model, and forward engineer deployment scripts for the DBA team.
erwin Data Modeler has greatly helped us maintain a SDLC for database changes and version control.
  • erwin Data Modeler helps generate deployment scripts for database deployments without the need to worry about programming syntax.
  • It helps you compare different models pretty easily and identify any discrepancies induced due to human error during deployment cycles.
  • I have a great experience of using erwin Data Modeler to generate database models straight out of database SQL file. This feature is called reverse engineering in erwin Data Modeler world.
  • erwin Data Modeler allows only 25 entities in a trial version. It really limits you when you want to try out the product before actually deciding to pay for licensing cost. It would be rather helpful if they limit the trial period by days instead.
  • The UI is pretty good but sometimes the large diagrams are hard to manage. A little improvement in that area would be helpful.
I have had a chance to use few other data modeling tools from Quest and Oracle, but I am most comfortable using erwin Data Modeler. They understand your data modeling needs and have designed the software to give you a feeling of completeness when you are designing a data model.
