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

"We have seen ROI with this solution over the years that we have used it.""The user interface is good. It's both clear and comprehensible. It's easy to work with."

More IBM Rational System Architect Pros »

"The interface is really simple to use and it allows me to pick and choose which tables I want to reverse engineer.""Straightforward setup.""The data modeling module is important to me because I am a database developer and designer... It's very fast, reliable, up-to-date, so easy to use, smooth.""IDERA keeps up with the versions of Oracle and SQL Server that I'm using. I mostly use SQL Server and when there are new features, a new type of index, for example, IDERA also includes them in upgrades of the data modeling tool.""It's much easier to develop the database structure and change it on the fly, rather than doing it manually in SQL Server itself. That saves time.""The most important features are logical and physical models that we can compare and develop. Also, the Data Dictionary can be created out of your studio. Finally, database schemas help understand the logic that's behind the scene, behind the SQL tables. Especially when there are a lot of them, the schemas help everyone understand the business processes.""We use the solution to create data models which describe our company's data architecture"

More IDERA ER/Studio Pros »

"This solution can be more user-friendly and easier to use, with better dashboards.""There needs to be more information at the outset about how to use the solution and how to deploy it. The deployment process needs improvement."

More IBM Rational System Architect Cons »

"The visual presentation is a little too colorful and seems that it is dumbed down.""This solution needs more precise documentation.""The only thing I had an issue with was licensing, and the support was very good.""when there are some links to the external databases, if this database is not structured it is not uploaded. It gives me errors and I cannot see the view that was created on this structure and I cannot change those views, even manually. It skips the views. I have to ignore those views. I cannot re-upload them because it gives me an error.""I would like to upload, a database with about 3,000 tables. It takes so much time and, finally, it freezes the whole solution so that I actually cannot work with that environment. For the data warehouse, it's fine because I have 20 or 30 tables. It works fine. But, when I reverse-engineer the database with 3,000 tables, it freezes and it's hard to upload and reverse-engineer such environments in ER/Studio.""The solution could be sped up, as it is a little slow (e.g., when it's doing its database compare).""The screens are a bit outdated. They could use a new look and feel."

Pricing and Cost Advice
Information Not Available
"I am currently using the trial version, but this solution is definitely worth considering for the price point.""It is priced fairly. It's around the same as erwin and other competitors' costs.""Pricing is expensive and on the higher-end.""At my previous company using ER/Studio, a database compare took four hours before using the product and 15 minutes after using the product."
