IT Admin at a logistics company with 10,001+ employees

Scalability and the online maintainability of definitions are definite advantages for us

We've had it for so long, so it's status quo. But we've added all sorts of functionality to our applications and there are no issues with databases. Anything developers request, we're able to accomplish. Also, we deal a lot with government regulation - and not to talk about what the company does - but anything that they require of us, because we transmit data back and forth with them, we're able to do that with no problems. And there have been a lot of changes over the past five years that our government dictated regarding what we actually end up doing. So, we're able to be extremely flexible with that.

Data Architect at a financial services firm with 10,001+ employees

Improved data modeling has reduced system footprint and strengthened finance workflows

I assess the benefits of IDERA ER_Studio's metadata management for my organization as not as good as Erwin's. Erwin's metadata management is better in how it handles data. There is a lot more user involvement in managing the metadata, primarily because in IDERA ER_Studio, the logical and physical models are separately defined in the same file, so you have to map them every single time. In Erwin, it has a unified structure, so if you make a change in the logical model, it automatically shows up in the physical model. You have to go through a couple of steps in the IDERA model to make sure everything has moved over. While that is not that inconvenient when you are actually doing development, as far as metadata management, that is prone to things getting dropped and missed. The collaboration tools in IDERA ER_Studio are adequate, but I think with Erwin, there is more of an opportunity for things to crash. Changes can be merged in IDERA more fluidly; however, the locking and sharing are a little bit more defined in Erwin. I think the learning curve for Erwin might be easier than IDERA ER_Studio, especially with connecting to different models and systems.

Quotes from Members

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

Pros

"Nowadays, CA is doing a lot of improving as far as online maintainability of definitions, which is a huge improvement over the past. I'm able to do a lot of changes without any outage."

"The initial setup is fairly straightforward for a mainframe product."

"It definitely cuts down on our support costs. I do not get woken up in the middle of the night very often for a problem with Datacom."

"It is a solid product."

"Scalability is definitely one thing. The size of the database can grow without any issues. We've got one database table that's got over a billion rows in it; quite a bit of data, and it handles access like a champ."

"I like the fact that it has a scripting language that allows you to automate and write your own scripts."

"The interface is really simple to use and it allows me to pick and choose which tables I want to reverse engineer."

"The most valuable features are... those that enable me to represent the database to the development community and the business users."

"Data lineage tracking: It allows us to identify upstream and downstream systems using data."

"ER/Studio is excellent for large teams; it scales well to teams of over one hundred plus people."

"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'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."

Cons

"For the "no-outage maintainability" of things, they are making improvements as we speak, but there is definitely still room for more of that."

"The only minor issue that we have had with Datacom is in the installation guide: Some of the sizings for the databases have not really worked out for us, so we had to go in and resize them."

"We would always like to see Repository performance improve, checking in and checking out."

"This solution needs more precise documentation."

"There was no specific mention of areas needing improvement."

"I assess the benefits of IDERA ER_Studio's metadata management for my organization as not as good as Erwin's."

"The only thing I had an issue with was licensing, and the support was very good."

"When building the relationships there should be a little more flexibility."

"ER/Studio lacks a pure cloud option for deployment."

"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."
