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

"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."
"We have a database design group of about 15 people. The Repository enables multiple people to work on the same model at the same time. We have fully integrated models, so we have one model for the enterprise data warehouse, one model for MDM, with a lot of sub-models in these things. People work on different parts of the model at different times. So the repository enables us to share the models, and keep track of what everybody is working on."
"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."
"I like the fact that it has a scripting language that allows you to automate and write your own scripts."
"We are able to document the data lineage and data flows of our data from one system to another."
"Customer Service: It's good."
"My overall rating for the solution is ten out of ten."
"Our primary use case of this solution is to design our database."
"Toad allowed us to run the query on the cloud DB and return data from the query, making things much faster."
"Horizontal layout for each connected database connection makes it easy to work with multiple databases at the same time."
"Toad is 100% value for money product."
"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."
"With Toad, all the users have the same database on the server rather than local individual databases which creates a lot of duplication."
"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 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."
 

Cons

"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."
"What needs the most improvement are semantic lineage and usability."
"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."
"ER/Studio lacks a pure cloud option for deployment."
"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."
"It is expensive! Licensing requires a subscription to their support site."
"We would always like to see Repository performance improve, checking in and checking out."
"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"
"Many users don't know how to add licensing to Toad, or where it is shown, so they could make that easier."
"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."
"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."
"Toad crashes sometimes and it will lose all the saved database information."
"It's way overpriced, even if it wasn't the buggy product it has become."
"What could be improved in Toad Data Modeler is stability and the complex setup."
"The product should provide better debugging features."
 

Pricing and Cost Advice

"As an individual user, the renewal is a little costly."
"I'm a firm believer that all software is overpriced these days but, comparatively speaking, I think ER/Studio is worth the money."
"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."
"I am currently using the trial version, but this solution is definitely worth considering for the price point."
"Pricing is expensive and on the higher-end."
"The price of this product is okay."
"I use the product's trial version."
"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."
