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

"You will save time, switching from whatever product you're using."
"I set up this tool and found it to be very simple."
"We can track changes to our data models and tie those changes back to specific tasks or efforts that we identify."
"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."
"IDERA ER_Studio does a lot more and performs model comparison much better than Erwin."
"Customer Service: It's good."
"Intuitive user interface provides for quick learning curve."
"With Toad, all the users have the same database on the server rather than local individual databases which creates a lot of duplication."
"Toad allowed us to run the query on the cloud DB and return data from the query, making things much faster."
"The most valuable features are the database architecture, the good functionality, and the user interface."
"I have used it for over six years."
"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."
"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."
"The feature I really like is the graphical part, especially the control of the relationships."
"This product is fast to learn and a user-friendly tool."
 

Cons

"The solution could be sped up, as it is a little slow (e.g., when it's doing its database compare)."
"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."
"This version does not properly generate SQL Server computed columns; future versions do this."
"The screens are a bit outdated. They could use a new look and feel."
"Documentation tends to range from pointless to incomprehensible."
"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. You cannot do it globally. Another issue concerns defining the foreign keys between the different tables. It is a little more tedious in the ER/Studio than in ERrwin. With ERwin it is direct."
"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."
"Tech support is a sticking point with me. I am really disappointed in the tech support. We pay for the Platinum level. It takes hours to get a response."
"Toad crashes sometimes and it will lose all the saved database information."
"Reverse engineering the physical schema is complex and can be made easier."
"Better documentation would be a benefit."
"Sometimes, Toad crashes without a clue as to why, and it needs an immediate restart."
"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."
"What could be improved in Toad Data Modeler is stability and the complex setup."
"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."
 

Pricing and Cost Advice

"It is priced fairly. It's around the same as erwin and other competitors' costs."
"I use the product's trial version."
"The setup cost may have been around $1500 to $2000."
"Pricing is on point, but do your due diligence - not every developer needs the tool."
"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."
"I feel the product's pricing is a good value."
"Pricing is expensive and on the higher-end."
"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."
