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

"I think ER/Studio Data Architect is priced high, but it comes with user-friendly features."

"My overall rating for the solution is ten out of ten."

"It's a great tool for modeling and I'm generally very happy with its features."

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

"Before this tool, just managing the changes and publishing the models to the users became very cumbersome, and this tool has simplified our day-to-day tasks a lot."

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

More IDERA ER/Studio pros

"I found all features valuable and necessary in Toad Data Modeler, particularly how good the solution is for modeling, database schema generation, and database re-engineering. I also found Toad Data Modeler straightforward to use."

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

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

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

"SQL Developer is much better than it was."

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

"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."

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."

"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."

"I would like to upload a database with about 3,000 tables. It takes so much time and, finally, it freezes the whole solution so that I actually cannot work with that environment."

"When building the relationships there should be a little more flexibility."

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

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

"when there are some links to the external databases, if this database is not structured it is not uploaded. It gives me errors and I cannot see the view that was created on this structure and I cannot change those views, even manually. It skips the views. I have to ignore those views. I cannot re-upload them because it gives me an error."

"The print facility is a little lacking."

More IDERA ER/Studio cons

"Reverse engineering the physical schema is complex and can be made easier."

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

"There were issues due to the databases connectivity."

"Better documentation would be a benefit."

"It is not feasible for small businesses. It is not used in a small company."

"Toad crashes sometimes and it will lose all the saved database information."

"What could be improved in Toad Data Modeler is stability and the complex setup."

"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."

More Toad Data Modeler cons

Pricing and Cost Advice

"I use the product's trial version."

"The solution’s pricing is high."

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

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

"The product is pricey."

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

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

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

More IDERA ER/Studio pricing and cost advice

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

"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."
