KaiQuale

Senior engineer at a government with 201-500 employees

Creates intuitive diagrams with comprehensive control over relationships

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

"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."

"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."

"Straightforward setup."

"Modeling with Data Architect: We can quickly reverse-engineer a database from an existing database or create a model from scratch."

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

"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."

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

"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

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

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

"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."

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

Cons

"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."

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

"It would be helpful if they could create a generic JSON database type, as a target database, rather than a specific one like Mongo."

"It isn't easy to compare the thousands of tables in the model against the database. The tool should improve the synchronization within the large organization"

"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."

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

"They allow functionalities to be released before the full tests for catching and correcting errors are completed."

More IDERA ER/Studio cons

"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."

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

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

"The product should provide better debugging features."

Pricing and Cost Advice

"The solution’s pricing is high."

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

"I use the product's trial version."

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

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

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

"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."

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

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."
