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

"Within a week of installation I had reverse engineered several existing databases into physical data models with basic data dictionaries and published them on the company wiki."

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

"I set up this tool and found it to be very simple."

"Overall, the product is very powerful and versatile for the task it's designed to do."

"We have been able to quickly create models for our enterprise-wide databases, even when some of them are third-party databases."

"The most valuable feature is data modeling, primarily, because it's something that has been lacking in our systems development for 20 years."

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

"One example is the use of the product to make extracts and split databases, and we were selling parts of the company to other regions of other companies, and it made the process more efficient and faster and less costly."

More IDERA ER/Studio pros

"There were lots of different requirements, and collaboration and review is one of the biggest things, there is also Office 360 integration, and there's flexibility to use it as a database as well."

"The solution is easily modified to suit your needs."

"From September 2014 through January 2015, I received help from the tech support staff of iServer, who were very prompt and almost instantaneously responded, and if it was something difficult, they brought three to four people to talk with me and then solved the problem within minutes."

"I love how there are no milestone swimlanes."

"I have to think less with this solution. It's simple."

"This flexibility is the most helpful part in the standard version."

"The solution has wide use within Microsoft products, and the integration with Microsoft products, in particular Microsoft Office, is great."

"The initial setup is easy."

More iServer pros

Cons

"It is expensive! Licensing requires a subscription to their support site."

"The visual presentation is a little too colorful and seems that it is dumbed down."

"Diagram versioning is not very intuitive Data Dictionary Bindings is not very intuitive"

"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)."

"The repository causes continuous problems, as it's slow and sometimes crashes."

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

"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."

More IDERA ER/Studio cons

"The one issue is that if you want to import predefined work, you need to put the licensing model in."

"There are other solutions out there that have a better user interface."

"Overall, I would say that it's a poor man's EA repository. It seems like a good idea, but doesn't really work in practice."

"We could allocate permissions to use only specific components to the users rather than the entire instance."

"I do not find it friendly to use."

"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."

"The migration tool needs to be included in the main package, and not as a separate license."

"I haven't used this solution long enough to know what areas could be improved."

More iServer cons

Pricing and Cost Advice

"The price of this product is okay."

"The process of licensing could be much simpler, from our experience."

"Pricing is on point, but do your due diligence - not every developer needs the tool."

"At my previous company using ER/Studio, a database compare took four hours before using the product and 15 minutes after using the product."

"The product is pricey."

"I use the product's trial version."

"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."

"Pricing is expensive and on the higher-end."

More IDERA ER/Studio pricing and cost advice

"The price of iServer is reasonable compared to other solutions."

"Aim for the exact number of people who shall define/review approve and view the processes, as it will impact the cost."

"The solution is cheaper than its competitors."

"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."

"It's about 13K to set up and 9K for the license for three months. I think it's about 20K a year, but we haven't firmed up on pricing yet because the price depends on how long we commit to the solution."

"The product has a moderate pricing."
