erwin Data Modeler has positively impacted my organization by allowing us to implement the data architecture with the data strategy about six to eight years ago, since it allowed us to have a single language and implement new Nissan standards, naming conventions, constraints, and features.

In erwin Data Modeler, areas that have room for improvement include performance improvements. I see that large models sometimes cause it to be slow when opening.

As erwin Data Modeler files get larger, the response time really slows down, and when I have multiple files open I sometimes get a glitch where a lot of the text fields get solid black and the first eight characters of column names might be blacked out with a rectangle.

The experience with pricing, setup cost, and licensing is that the licensing process is painful and quite onerous.

It has a very steep learning curve, limited support for NoSQL or streaming systems, and potentially a high licensing cost.

While I do not have knowledge about pricing for erwin Data Modeler, I think it could improve by having a feature that allows the publishing of models, similar to how Power BI allows for dashboard publishing for different users within an organization, not just data modelers.

What I did not like was that sometimes while I was creating relations, I was not getting errors. The errors only appeared when I tried to upload the model into a new database, which took a lot of time because I was creating a model, reproducing XML, and then trying to add the XML in the database.

Regarding improvements, the first thing I would mention is that every release has some issues, some of which are related to current functionalities, which means they often seem not very well tested or affected in the development process of the new version, leading to issues until that is released.

Erwin Data Modeler is a good product, but I recently experienced a problem where I was not able to open an erwin Data Modeler file because its version had automatically changed.
