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.

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.
