Currently in the market, there is no competitor to erwin Data Modeler; everything is very powerful, such as performing reverse engineering from an existing database and deploying that on Databricks or Snowflake.

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.

I would rate the visualization feature in erwin Data Modeler a six out of ten because the visualization is somewhat poor and some of the features are not user-friendly.

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.

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.
