We performed a comparison between IBM Rational System Architect and IDERA ER/Studio based on real PeerSpot user reviews.
Find out what your peers are saying about LeanIX, Sparx Systems, erwin by Quest and others in Enterprise Architecture Management."There are a lot of features I find valuable, but I think that the metamodel customization is one of the best features that the solution offers."
"The solution is pretty stable."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"We have seen ROI with this solution over the years that we have used it."
"Straightforward setup."
"We use the solution to create data models which describe our company's data architecture"
"We are able to document the data lineage and data flows of our data from one system to another."
"Valuable features include the ability to visually represent what the database tables are going to look like and their relationships. Also, the ability to document the definitions of the tables and the columns that are in a table so that we can communicate what the data is and how it should be used."
"It's easy to model and has a user-friendly interface. I like the team portal because, once we upload, the entire team can see the model."
"It does the job."
"The interface is really simple to use and it allows me to pick and choose which tables I want to reverse engineer."
"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 reverse engineering of the database is already there, but in the next release I would like to see some pilot supplied with the solution in order to address any database."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"It isn't easy to compare the thousands of tables in the model against the database. The tool should improve the synchronization within the large organization"
"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."
"It would be helpful if they could create a generic JSON database type, as a target database, rather than a specific one like Mongo."
"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."
"One limitation I have found in ER/Studio is that when you want to make some changes to the table definitions, you have to go item by item. You cannot do it globally. Another issue concerns defining the foreign keys between the different tables. It is a little more tedious in the ER/Studio than in ERrwin. With ERwin it is direct."
"I would like to see better documentation/help for the Data Architect tool. Creation of tutorials would be nice, as there are some features which are not as clearly defined as they should be."
"Whenever there is a new version, there are a lot of release notes on the technical side of it, but I would like to be told why are we doing the upgrade... What I would like to really see is how this benefits us from the business point of view. What are the real benefits that the user gets? I want some kind of way white paper. The release notes describe the technical enhancements but, from the layman's point of view, if someone asks me what are the business benefits of this upgrade, I don't have any documentation to explain it to the business."
"What I would like to see improved is the reliability of the releases, releases that are a little less buggy."
