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

"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."
"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."
"I think ER/Studio Data Architect is priced high, but it comes with user-friendly features."
"It was a very good tool at the time since it was complete."
"We use it either to help an organization understand what data it has got or to design a database."
"ER/Studio is excellent for large teams; it scales well to teams of over one hundred plus people."
"We are able to document the data lineage and data flows of our data from one system to another."
"It's much easier to develop the database structure and change it on the fly, rather than doing it manually in SQL Server itself, which saves time."
"Ability to save my custom queries and Macros"
"SQL Developer is much better than it was."
"With Toad, all the users have the same database on the server rather than local individual databases which creates a lot of duplication."
"It was immensely helpful in collecting SQL database data, especially as I am not a database admin/engineer."
"It's a must-buy, and both pricing and licensing is well in the range of every organization."
"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 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 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."
 

Cons

"Tech support hasn't been as good lately as it was in the past. It is down to average."
"I assess the benefits of IDERA ER_Studio's metadata management for my organization as not as good as Erwin's."
"ER/Studio lacks a pure cloud option for deployment."
"Sometimes our version is a little unstable. But I think this problem occurs because our version is old."
"The model diagram because very clumsy when you save it on the team server and the models are very big."
"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."
"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."
"We did have a big issue when we upgraded to the 2016 version. The Team Server portion never did quite install correctly, and/or the database was corrupted, and we never figured it out."
"There were issues due to the databases connectivity."
"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 is not feasible for small businesses. It is not used in a small company."
"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."
"Currently, with Windows 10, it sometimes would get stuck and stop responding."
"Toad crashes sometimes and it will lose all the saved database information."
"Many users don't know how to add licensing to Toad, or where it is shown, so they could make that easier."
 

Pricing and Cost Advice

"The setup cost may have been around $1500 to $2000."
"Pricing is expensive and on the higher-end."
"It is priced fairly. It's around the same as erwin and other competitors' costs."
"The process of licensing could be much simpler, from our experience."
"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."
"As an individual user, the renewal is a little costly."
"Pricing is on point, but do your due diligence - not every developer needs the tool."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"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."
