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

"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."

"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."

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

"It is a solid product."

"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."

"We have a database design group of about 15 people. The Repository enables multiple people to work on the same model at the same time. We have fully integrated models, so we have one model for the enterprise data warehouse, one model for MDM, with a lot of sub-models in these things. People work on different parts of the model at different times. So the repository enables us to share the models, and keep track of what everybody is working on."

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

"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."

"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."

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

"The most valuable feature of the solution is generating DDL (data definition language)."

"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."

More IDERA ER/Studio pros

Cons

"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."

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

"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."

"Sometimes our version is a little unstable. But I think this problem occurs because our version is old."

"The model diagram because very clumsy when you save it on the team server and the models are very big."

"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."

"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."

"This solution needs more precise documentation."

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

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