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.

1) When updating a model after generating a schema, if only a few tables are imported, the tool assumes you want to delete the rest. If you have a large model, you repeatedly have to clarify that you don't want to delete each one. 2) If one could view the same model on physical, logical, and conceptual levels while retaining all information specific to each level (including layout), that would be excellent.

Quotes from Members

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

Pros

"Developing new dimensional models; for the data we're hosting, dimensional modeling is more useful."

"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."

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

"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."

"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."

"This has helped the new application development team in cross-verifying, and understanding, the current setup, proposing and architecting new solutions for the organisation."

"One of the valuable features is inheritance when joining tables. When setting up RI and domains and rules, ER/Studio does a lot of the grunt, boilerplate code that would otherwise have to be hand-coded."

"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."

More IDERA ER/Studio pros

"TOAD makes it easy to code and compile stored procedures, is easy to find and edit code, offers the ability to debug and test, and is a great tool that saves a lot of time because it has a lot of components all in one tool so you don’t need to open or use other apps or the command line."

"It is a very good option for creating and editing SQL scripts, especially large ones that I have run in support of government billing applications."

"I have used it for over six years."

"This product is fast to learn and a user-friendly tool."

"The feature I really like is the graphical part, especially the control of the relationships."

"It was immensely helpful in collecting SQL database data, especially as I am not a database admin/engineer."

"I don't know the financials, but I wouldn’t be able to do my job (build applications/databases) without it."

"The most valuable features are the database architecture, the good functionality, and the user interface."

More Toad Data Modeler pros

Cons

"What I would like to see improved is the reliability of the releases, releases that are a little less buggy."

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

"The solution could be sped up, as it is a little slow (e.g., when it's doing its database compare)."

"The screens are a bit outdated. They could use a new look and feel."

"This solution needs more precise documentation."

"Tech support is a sticking point with me. I am really disappointed in the tech support. We pay for the Platinum level. It takes hours to get a response."

"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."

"Installation of the product itself is straight forward although the licensing process is awkward and confusing at best."

More IDERA ER/Studio cons

"It's quite stable but takes a bit of a time to run SQL queries if the database is huge."

"When updating a model after generating a schema, if only a few tables are imported, the tool assumes you want to delete the rest, which is cumbersome."

"Many users don't know how to add licensing to Toad, or where it is shown, so they could make that easier."

"We sometimes have issues with multiple nested queries. They take a long time to run, and it would be nice to have them run faster."

"There were issues due to the databases connectivity."

"It's way overpriced, even if it wasn't the buggy product it has become."

"Sometimes, Toad crashes without a clue as to why, and it needs an immediate restart."

"Better documentation would be a benefit."

More Toad Data Modeler cons

Pricing and Cost Advice

"It is priced fairly. It's around the same as erwin and other competitors' costs."

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

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

"As an individual user, the renewal is a little costly."

"The solution’s pricing is high."

"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."

"The price of this product is okay."

"I am currently using the trial version, but this solution is definitely worth considering for the price point."

More IDERA ER/Studio pricing and cost advice

"Price-wise, the lesser it is, the better it is for me, especially in Egypt. I think that the licensing cost ranges from 1,000 to 9,000. Also, it includes maintenance and support for a year."

"Though I'm not involved in the licensing for Toad Data Modeler, I believe it's per user and not cheap."
