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.

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

"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."
"The initial setup is fairly straightforward for a mainframe 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."
"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."
"I set up this tool and found it to be very simple."
"Developing new dimensional models; for the data we're hosting, dimensional modeling is more useful."
"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."
"We are able to document the data lineage and data flows of our data from one system to another."
"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."
"The tool is simple to use."
"It does the job."
"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."
 

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."
"ER/Studio lacks a pure cloud option for deployment."
"We would always like to see Repository performance improve, checking in and checking out."
"The solution is not so strong at creating modeling views and database views."
"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."
"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."
"This solution needs more precise documentation."
"The solution could be sped up, as it is a little slow (e.g., when it's doing its database compare)."
"There was no specific mention of areas needing improvement."
 

Pricing and Cost Advice

Information not available
"The product is pricey."
"The price of this product is okay."
"I use the product's trial version."
"At my previous company using ER/Studio, a database compare took four hours before using the product and 15 minutes after using the product."
"On a scale of one to ten, where one is bad and ten is good, I would rate the licensing cost as a seven or eight. It's not too expensive for us."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"Pricing is expensive and on the higher-end."
"I feel the product's pricing is a good value."
