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."
"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."
"The solution is pretty stable."
"SAP PowerDesigner is an excellent tool that does what I need it to do. What I like most about it is that it's stable, fast, and easy to understand."
"It's a stable system. It never crashes."
"The feature I found valuable in SAP PowerDesigner is extraction. I also like that my company hasn't faced any issues because of the clear documentation about SAP PowerDesigner."
"Very good repository features."
"The solution is a very pragmatic tool. It's quite easy to use."
"The most valuable feature is that it is a very fast reverse engineering process. It does a very expansive comparison."
"Provides the flexibility to create logical and conceptual data models."
"I mostly work on the conceptual and logical side of things, and I enjoy how easy it is to use."
"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."
"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."
"This solution can be more user-friendly and easier to use, with better dashboards."
"The solution needs to better integrate with other products, like Microsoft."
"In the future, I would like to see data manipulation capability where you can actually write SQL queries and manipulate data from directly within the tool."
"Technical support could be better and more human."
"Not very intuitive or user-friendly."
"It would be helpful if there were glossary, catalog and governance tools. It would help make it a true end-to-end product."
"The data governance should be improved, like ER/Studio."
"SAP PowerDesigner can improve the ease of use. It is not the best tool on the market because it is tough to navigate and use. A beginner would not be able to use it well, it requires some experience. If the solution was more user-friendly it would be able to be used by more audiences. I do not think many people are aware of this solution and they should use it."
"The focus is more on mainstream development environments, and I see a lack of focus on the open source world. I think SAP PowerDesigner probably interfaces better with SQL Server and Db2 but not with open source databases like PostgreSQL and MySQL."
"You have the possibility to complete a connection for abbreviations if you are creating columns or names of the tables. In the Citrix environment, this has been lagging to the point where the PowerDesigner was not usable."
