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

"Valuable features include the ability to visually represent what the database tables are going to look like and their relationships. Also, the ability to document the definitions of the tables and the columns that are in a table so that we can communicate what the data is and how it should be used."
"We use it either to help an organization understand what data it has got or to design a database."
"Overall, the product is very powerful and versatile for the task it's designed to do."
"I like the fact that it has a scripting language that allows you to automate and write your own scripts."
"It does the job."
"I think it's the best due to pricing and good overall support."
"Intuitive user interface provides for quick learning curve."
"It was a very good tool at the time since it was complete."
"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."
"Toad allowed us to run the query on the cloud DB and return data from the query, making things much faster."
"I don't know the financials, but I wouldn’t be able to do my job (build applications/databases) without it."
"The feature I really like is the graphical part, especially the control of the relationships."
"Ability to save my custom queries and Macros"
"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."
"Horizontal layout for each connected database connection makes it easy to work with multiple databases at the same time."
"It was immensely helpful in collecting SQL database data, especially as I am not a database admin/engineer."
 

Cons

"I would like to see better documentation/help for the Data Architect tool. Creation of tutorials would be nice, as there are some features which are not as clearly defined as they should be."
"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."
"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."
"Documentation tends to range from pointless to incomprehensible."
"The model diagram because very clumsy when you save it on the team server and the models are very big."
"There have been some issues with performance, and there are some issues with inconsistencies."
"It would be helpful if they could create a generic JSON database type, as a target database, rather than a specific one like Mongo."
"Sometimes our version is a little unstable. But I think this problem occurs because our version is old."
"There were issues due to the databases connectivity."
"Toad crashes sometimes and it will lose all the saved database information."
"Better documentation would be a benefit."
"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."
"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."
"It's way overpriced, even if it wasn't the buggy product it has become."
"The one thing about it is that there are almost too many features and options; some we don’t even use."
 

Pricing and Cost Advice

"The product is pricey."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"The solution’s pricing is high."
"Pricing is expensive and on the higher-end."
"I feel the product's pricing is a good value."
"Pricing is on point, but do your due diligence - not every developer needs the tool."
"The price of this product is okay."
"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."
"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."
