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.

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

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

"We can track changes to our data models and tie those changes back to specific tasks or efforts that we identify."

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

"Our primary use case of this solution is to design our database."

"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."

"We found a lot of duplication, a lot of non-conformity in the way our databases were designed. By identifying these situations, we're able to go back in and try to create a more standardized solution."

"The reverse engineering is the most important feature."

"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

"With Toad, all the users have the same database on the server rather than local individual databases which creates a lot of duplication."

"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."

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

"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, because you can move them around any way you want, which makes it easy to create a comprehensive and easy-to-understand diagram."

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

"Toad is 100% value for money product."

"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."

More Toad Data Modeler pros

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."

"The deployment and licensing facets of this product are beyond maddening, requiring even small organizations such as ours to install and maintain two server apps to handle real-time license enforcement and centralized (Tool Cloud) product launching."

"The solution is not so strong at creating modeling views and database views."

"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."

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

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

"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."

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

More IDERA ER/Studio cons

"Better documentation would be a benefit."

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

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

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

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

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

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

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

More Toad Data Modeler cons

Pricing and Cost Advice

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

"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."

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

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

"The product is pricey."

"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."

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."
