We performed a comparison between erwin Data Modeler by Quest and IDERA ER/Studio based on real PeerSpot user reviews.
Find out in this report how the two Enterprise Architecture Management solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."There is absolutely no problem with the stability."
"The fitting model is very intuitive."
"The solution's ability to compare and synchronize data sources with data models is fantastic. We use it for that on a regular basis to make sure that changes haven't been made to the database outside of the modeling process. I can take existing databases and reverse engineer them and understand their structure within 15 minutes. If I didn't have Data Modeler it would take hours. It increases our productivity and helps in understanding our legacy application."
"It supports a wide variety of databases, including the latest ones. We have chosen to go for a cloud-based database, and it supports that, which is very useful."
"erwin has versioning so you can keep versions, over time, of those models and you can compare any version to any version. If you're looking at a specific database and you want to see what changed over time, that's really useful. You can go back to a different version or connect that to your change-control processes so you can see what was released when."
"The ability to collaborate between different members across the organization is the most valuable feature. It gives us the ability to work on the same model, regardless of where we are physically."
"When you're getting down to the database level, where you're building a design and you're creating DDL out of it, or you're going in the other direction where you're reaching into system catalogs and bringing things back, that starts to really require specialization. Visio isn't going to reverse-engineer that for you. Those features in erwin are valuable."
"The data lineage feature is very valuable."
"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."
"It does the job."
"When validating the model, the ability to provide sub-models to developers, and generate a physical model from the logical, makes it easier to review a logical model with stakeholders."
"We have been able to quickly create models for our enterprise-wide databases, even when some of them are third-party databases."
"The reverse engineering is the most important feature."
"One of the valuable features is inheritance when joining tables. When setting up RI and domains and rules, ER/Studio does a lot of the grunt, boilerplate code that would otherwise have to be hand-coded."
"This application does a lot of things, as do competitor products, but the main reason to go with this product was the ability to create many automations, where we can improve our work and our process."
"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."
"The navigation is a little bit of a challenge. It's painful. For example, if you've got a view open and you want to try to move from side to side, the standard today is being able to drag and drop left and right. You can't really do that in the model. Moving around the model is painful because it doesn't follow the Windows model today."
"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."
"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."
"The only real complaint I have is the time it takes to do a database comparison on a large model. If they could speed that up, that would be the only thing I can think of that needs improvement."
"I would like the solution to be more user-friendly to deploy."
"The erwin ETL functionality has room for improvement when it comes to mapping databases with a classic entity-relationship model to a data warehouse model."
"I still use Visio for conceptual modeling, and that's mainly because it is easier to change things, and you can relax some of the rules. DM's eventual target is a database, which means you actually have to dot all the Is and cross all the Ts, but in a conceptual model, you don't often know what you're working with. So, that's probably a constraint with erwin. They have made it a lot easier, and they've done a lot, but there is probably still room for improvement in terms of the ease of presentation back to the business. I'm comparing it with something like Visio where you can change colors on a box, change the text color and that sort of stuff, and change the lines. Such things are a whole lot easier in Visio, but once you get a theme organized in erwin, you can apply that theme to all of the objects. So, it becomes easier, but you do have to set up that theme."
"We can only get licenses through partners."
"Sometimes our version is a little unstable. But I think this problem occurs because our version is old."
"When building the relationships there should be a little more flexibility."
"The only thing I had an issue with was licensing, and the support was very good."
"This solution needs more precise documentation."
"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."
"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."
"What needs the most improvement are semantic lineage and usability."
