Lots of valuable features, especially the metamodel customization
In terms of what could be improved, we did not take the whole package with all the modules, and I think that the integration with other platforms like Office could be better. 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.

Used for data modeling and has a scripting language to write your own scripts
The solution has streamlined our data modeling processes quite a bit. It's a central focus in our data modeling and data cataloging efforts. The tool's reverse engineering capability to bring in existing database structures and create models from them has benefitted our data architecture needs. With the tool's data dictionary capability, we're able to maintain consistency in our models, name use, and actual data domains. The solution's reverse engineering helps with understanding legacy databases. In fact, I've been asked to reverse-engineer several more legacy databases so that we can have them modeled and cataloged. The solution is deployed on the cloud server, but it’s only within our network. The solution has a lot of capabilities. I like the fact that it has a scripting language that allows you to automate and write your own scripts. I think that's been a big bonus for us. I highly recommend the solution because of its capability for logical models, where you can put your business definitions and logic. While less expensive, some other tools can't do that. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"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."
"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."
"Data lineage tracking: It allows us to identify upstream and downstream systems using data."
"The most valuable feature of the solution is generating DDL (data definition language)."
"I like the fact that it has a scripting language that allows you to automate and write your own scripts."
"Straightforward setup."
"Using this product has improved the way we maintain our models because they have a place where we can keep all of them, and they can be viewed using the web interface."
"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."
"The data modeling and reverse engineering features are most important to us."
"It does the job."
 

Cons

"This solution can be more user-friendly and easier to use, with better dashboards."
"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."
"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."
"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'd like the ability to debug the errors ourselves instead of having to call them. There are certain types of errors that, I wouldn't say they come up regularly, but when you have an error it is very often the same type of error. Knowing that it's a Type III or Type I, it would be nice to have some kind of debugging facility for us to use to find out where the problem that threw that error occurs. That would be a really cool feature."
"The screens are a bit outdated. They could use a new look and feel."
"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."
"What I would like to see improved is the reliability of the releases, releases that are a little less buggy."
"ER/Studio lacks a pure cloud option for deployment."
"What needs the most improvement are semantic lineage and usability."
"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."
