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

"Using this product has improved the way we maintain our models because they have a place where we can keep all of them, and they can be viewed using the web interface."
"I am able to create (and publish) logical data models, apply naming standards using macro, generate the physical models and DDL."
"We use it either to help an organization understand what data it has got or to design a database."
"I would 100% recommend the product."
"We use the solution to create data models which describe our company's data architecture"
"Because of all the various things we use it for, it has a high value within the organization."
"Overall, the product is very powerful and versatile for the task it's designed to do."
"I set up this tool and found it to be very simple."
"The feature I really like is the graphical part, especially the control of the relationships."
"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."
"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 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."
"Toad is 100% value for money product."
"SQL Developer is much better than it was."
"The most valuable features are the database architecture, the good functionality, and the user interface."
"With Toad, all the users have the same database on the server rather than local individual databases which creates a lot of duplication."
 

Cons

"ER/Studio lacks a pure cloud option for deployment."
"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"
"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."
"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 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."
"Installation of the product itself is straight forward although the licensing process is awkward and confusing at best."
"The only thing I had an issue with was licensing, and the support was very good."
"It is expensive! Licensing requires a subscription to their support site."
"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."
"Reverse engineering the physical schema is complex and can be made easier."
"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."
"Currently, with Windows 10, it sometimes would get stuck and stop responding."
"It's quite stable but takes a bit of a time to run SQL queries if the database is huge."
"Sometimes, Toad crashes without a clue as to why, and it needs an immediate restart."
"It's way overpriced, even if it wasn't the buggy product it has become."
 

Pricing and Cost Advice

"The product is pricey."
"The setup cost may have been around $1500 to $2000."
"The process of licensing could be much simpler, from our experience."
"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."
"I feel the product's pricing is a good value."
"I use the product's trial version."
"Pricing is on point, but do your due diligence - not every developer needs the tool."
"As an individual user, the renewal is a little costly."
"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."
