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

"It improved the way we were able to manage our models."
"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."
"Having well-documented and consistent schemas makes it easier to identify, understand, and prepare reliable data for analytics and new AI use cases, ensuring my data is AI-ready and reliable."
"If you want to have good data architecture, you need to have database design done."
"We can create mappings in erwin and possibly data dictionaries."
"Overall, erwin DM's support for Snowflake is very good."
"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's a safeguard for me because I'm always concerned that somebody is free handing it and will forget a key coming from the parent. The migrating keys are a great feature. Identifying relationships, non-identifying relationships, and being visually right there to understand the differences are great features. erwin is key to being able to visually understand whatever the customer is requesting. They'll give you words on a paper, but once they can actually view it as a picture, it really comes to life. The data comes to life to where they understand exactly what they're asking for."
"It has helped in supporting the development of an Enterprise Data Model."
 

Cons

"It has a very steep learning curve, limited support for NoSQL or streaming systems, and potentially a high licensing cost."
"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."
"I would like the solution to be less rigid in terms of its theory."
"Complete Compare is set up only to compare properties that are of interest to us, but some of the differences cannot be brought over from one version of the model to another. This is despite the fact that we are clicking to bring objects from one place to another. Therefore, it's hard to tell at times if Complete Compare is working as intended without having to manually go into the details and check everything. If it could be redesigned to a degree where it is easier to use when we bring things over from one site to another and be sure that it's been done correctly, that would be nice to have. We would probably use the tool more often if the Complete Compare were easier to use."
"The experience with pricing, setup cost, and licensing is that the licensing process is painful and quite onerous."
"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."
"I'd really like to see the PDF function become available. It would make my life much easier than what it is at the moment because whenever I need to collaborate with people that do not have erwin, I have to go through the wonkiness of going to Word and then save it from Word into PDF. There's a lot of differences between erwin 4.4 and 2020."
"Some Source official systems give us DDLs to work with and they have contents not required to be part of the DDL before we reverse engineer in the erwin DM. Therefore, we manually make changes to those scripts and edit them, then reverse-engineer within the tool. So, it does take some time to edit these DDL scripts generated by the source operational systems. What I would suggest: It would be helpful if there were a place within the erwin tool to import the file and automatically eliminate all the unnecessary lines of code, and just have the clean code built-in to generate the table/data model."
"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

"The price of erwin Data Modeler is very expensive, in particular for this part of the world."
"The solution is expensive."
"There are two license options and the pricing is reasonable."
"I wish it wasn't so expensive. I would love to personally buy a copy of my own and have it at home, because the next job that I'm looking at is probably project management and I might not have access to the tool. I would like to keep my ability to use the tool. Therefore, they should probably have a pricing for people like me who want to just use the solution as an independent consultant, trying to get started. $3,000 is a big hit."
"Though the solution is not cheap, it's worth the money."
"I don't specifically know what we're paying now. About three years ago, in another organization, I have this memory of 6,000 AUD a seat or something like that, but I am not sure. In the mid-2000s, it was something like 1,200 AUD a seat. I get the impression that there was a price jump when it was spun off from CA as a separate company, which is understandable, but it could sometimes be a barrier in some organizations picking it up. I haven't talked to erwin people yet, but I'm going to suggest to them that they could perhaps think of having an entry-level product that is priced a bit lower, and then, you can buy the extra suite."
"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."
"The primary reasons that erwin was selected were that it was much more affordable for us [than Embarcadero] and it was easily maintainable."
