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

"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."

"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."

"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."

"I feel the product's pricing is a good value."

"With both onshore and offshore development teams working 18x5 days, it is an easy way to control check-in's while also maintaining schema views."

"You will save time, switching from whatever product you're using."

"It is a very robust, industrial strength data modeling product, intended ideally for very large development projects where a good ROI can be obtained."

"The reverse engineering is the most important feature."

More IDERA ER/Studio pros

"Auto-complete is the best feature of the solution."

"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."

"It's a must-buy, and both pricing and licensing is well in the range of every organization."

"Toad allowed us to run the query on the cloud DB and return data from the query, making things much faster."

"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 have used it for over six years."

"SQL Developer is much better than it was."

Cons

"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."

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

"The screens are a bit outdated.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

"Documentation tends to range from pointless to incomprehensible."

"What needs the most improvement are semantic lineage and usability."

"Overall, I don't like any of the features and I think that it's a poor system."

"There have been some issues with performance, and there are some issues with inconsistencies."

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

More IDERA ER/Studio cons

"Although a lot of people get deceived by the name “Data Analysis”, it has capacity of any enterprise tool, but not to the point of creating multiple pipes in one integrated work-flow, batching the work-flows and running them parallel for data loads."

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

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

"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."

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

"The product should provide better debugging features."

"The one thing about it is that there are almost too many features and options; some we don’t even use."

"Currently, with Windows 10, it sometimes would get stuck and stop responding."

More Toad Data Modeler cons

Pricing and Cost Advice

"The solution’s pricing is high."

"The price of this product is okay."

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

"The setup cost may have been around $1500 to $2000."

"I feel the product's pricing is a good value."

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

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

"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."

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."
