Data modeling has transformed regulatory reporting and collaboration across cloud environments
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. Impact analysis can lag as well. Version control is another aspect. If we have developed a current version, it is not integrated with Git where we can easily compare different versions. UI modernization is also something we cannot utilize as it is primarily for development. Additionally, cloud-specific optimizations are needed when it comes to Snowflake or Databricks. When it comes to AI aspects, auto-suggestions for normalization or identifying primary, foreign, or surrogate keys are areas that can be improved.

It has helped in supporting the development of an Enterprise Data Model
Data model development: This has built-in ways to create multiple, separate solution data models, including ways to link to an Enterprise Data Model (EDM). Other objects are encyclopedia-wide and need a different approach for managing solution-specific diagrams with an ability to query, e.g…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We can create mappings in erwin and possibly data dictionaries."
"It is a scalable solution...The technical support team is fine."
"Overall, erwin DM's support for Snowflake is very good."
"The process of creating visual representations of data structures using erwin Data Modeler allows you to see everything you are doing, and you have visuals to see what you are going to do and what has been done so far."
"The ability to collaborate between different members across the organization is the most valuable feature. It gives us the ability to work on the same model, regardless of where we are physically."
"Erwin Data Modeler is well organized, and the screen layout is intuitive."
"The most valuable features are the ability to reverse engineer and do model comparison. With the reverse engineering, I can understand the databases from third-party products. With the model comparison, I can track the differences between two versions of the same database."
"The solution’s ability to generate database code from a model for a wide array of data sources cuts development time from two weeks to one day or even hours."
"It has helped in supporting the development of an Enterprise Data Model."
 

Cons

"In terms of new features, it would be great to have a cloud base. We should be able to put it on the cloud for better collaboration and data models sharing."
"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."
"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."
"The one drawback is if you have an extremely large complex model, the compare process can take quite a bit of time, more than four hours."
"I would like the solution to be more user-friendly to deploy."
"The solution only works with one server and one database, so I don't think it's scalable enough."
"The erwin Data Modeler is quite complex to use."
"The reverse engineering in Oracle Databases needs improvement, as there are issues."
"The product is very outdated software; complex to use, and the GUI is a fat client so no mobile or web access."
 

Pricing and Cost Advice

"There are no costs in addition to the standard licensing fees."
"erwin has this option where you pay a one-time fee and you have the license for six years, which makes sense because I don't upgrade my database engine every other year. I have an application that depends on it. This is something weird about PowerDesigner. There are no additional costs beyond the standard licensing fee."
"We've continued to use the product for many years and compared it with others on the market. The pricing is reasonable considering what the solution offers and what we pay. There are cheaper tools, but they may not be as robust and easy to use, so it's worth the money."
"The pricing of the solution is cheap. I rate the pricing a five out of ten."
"The price of erwin Data Modeler is very expensive, in particular for this part of the world."
"Price-wise, erwin Data Modeler is okay. You can purchase a single license and it is not very expensive."
"The price should be lower in order to be on the same level as its competitors."
"There is either a one-year or three-year license. It is not a pay-as-you-go license like a SaaS solution. It’s more of a traditional licensing. They are a little bit on the pricier side."
