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 is a solid product."
"They provide the best support compared to other providers I have used previously."
"This product is very stable, compared to a lot of other DBMSs that run in our shop."
"The technical support staff with whom I have dealt are truly top notch; they understand whatever issue or question we might have and are able to supply quick and valid answers much of the time, or they fully engage in developing solutions when that is required."
"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."
"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 does its job very well."
"It has cut down on our support, especially after hours, and it is a solid product that just works most of the time."
"Straightforward setup."
"This has helped the new application development team in cross-verifying, and understanding, the current setup, proposing and architecting new solutions for the organisation."
"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."
"I think it's the best due to pricing and good overall support."
"Developing new dimensional models; for the data we're hosting, dimensional modeling is more useful."
"It is a very robust, industrial strength data modeling product, intended ideally for very large development projects where a good ROI can be obtained."
"It's a great tool for modeling and I'm generally very happy with its features."
"You will save time, switching from whatever product you're using."
 

Cons

"There are a lot of features that come out with each upgrade, but our application that runs on it has been around for a long time; they sort of decommissioned this application."
"Something that we would like to see is for them to develop integration with open distribution systems."
"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."
"There are still some things - and I know they are working on some of them - but 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 had trouble with an upgrade once but, when I have trouble with the upgrade there's always someone there to support me and get me through it really quickly."
"The repository causes continuous problems, as it's slow and sometimes crashes."
"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."
"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."
"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."
"The deployment and licensing facets of this product are beyond maddening, requiring even small organizations such as ours to install and maintain two server apps to handle real-time license enforcement and centralized (Tool Cloud) product launching."
"What needs the most improvement are semantic lineage and usability."
"We receive these new functionalities, and sometimes we start to test them and we find errors that we need to correct by talking with tech support."
"ER/Studio lacks a pure cloud option for deployment."
 

Pricing and Cost Advice

"The product is pricey."
"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."
"Pricing is expensive and on the higher-end."
"I feel the product's pricing is a good value."
"The process of licensing could be much simpler, from our experience."
"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."
"As an individual user, the renewal is a little costly."
