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

"We are able to document the data lineage and data flows of our data from one system to another."
"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."
"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."
"Customer Service: It's good."
"Ease of use It looks good enough Ability to create HTML reports Ability to compare the model against the database"
"We use it either to help an organization understand what data it has got or to design a database."
"The data modeling and reverse engineering features are most important to us."
"It's easy to model and has a user-friendly interface. I like the team portal because, once we upload, the entire team can see the model."
"This product is fast to learn and a user-friendly tool."
"With Toad, all the users have the same database on the server rather than local individual databases which creates a lot of duplication."
"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."
"I have used it for over six years."
"The feature I really like is the graphical part, especially the control of the relationships."
"Ability to save my custom queries and Macros"
"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."
"The most valuable features are the database architecture, the good functionality, and the user interface."
 

Cons

"There have been some issues with performance, and there are some issues with inconsistencies."
"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."
"Whenever there is a new version, there are a lot of release notes on the technical side of it, but I would like to be told why are we doing the upgrade... What I would like to really see is how this benefits us from the business point of view. What are the real benefits that the user gets? I want some kind of way white paper. The release notes describe the technical enhancements but, from the layman's point of view, if someone asks me what are the business benefits of this upgrade, I don't have any documentation to explain it to the business."
"We would always like to see Repository performance improve, checking in and checking out."
"I assess the benefits of IDERA ER_Studio's metadata management for my organization as not as good as Erwin's."
"The solution could be sped up, as it is a little slow (e.g., when it's doing its database compare)."
"Overall, I don't like any of the features and I think that it's a poor system."
"The print facility is a little lacking."
"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."
"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."
"Reverse engineering the physical schema is complex and can be made easier."
"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."
"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

"It is priced fairly. It's around the same as erwin and other competitors' costs."
"The solution’s pricing is high."
"At my previous company using ER/Studio, a database compare took four hours before using the product and 15 minutes after using the product."
"The price of this product is okay."
"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."
"Pricing is expensive and on the higher-end."
"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."
"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."
