We performed a comparison between erwin Data Modeler by Quest and IDERA ER/Studio based on real PeerSpot user reviews.
Find out in this report how the two Enterprise Architecture Management solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."They have a lot of features and the most up-to-date technology integration, which I haven't seen in other products."
"The solution is excellent in providing a visual representation of a database and can generate DDL for implementing changes. We use DDL for logical purposes to review with business people, ensuring they have the required fields for processing. We also use it as a data dictionary for the physical data model to understand all the purposes of the terms. This helps us map the logical and physical terms with the business definition to understand our data."
"The solution's ability to compare and synchronize data sources with data models is fantastic. We use it for that on a regular basis to make sure that changes haven't been made to the database outside of the modeling process. I can take existing databases and reverse engineer them and understand their structure within 15 minutes. If I didn't have Data Modeler it would take hours. It increases our productivity and helps in understanding our legacy application."
"The modeling portion of the tool is the most valuable. There are some notes, naming standards, and other functions that we use as well. There's a whole boatload of functionality in this thing and we use maybe 10% of it. It seems to be pretty common that not all the functionality is fully utilized. But it's just got gobs and gobs of stuff that you can implement if you so choose to."
"Forward engineering, DDL generation, reverse engineering, and reporting are the most valuable features of the solution."
"The principal feature that I liked is that the solution has a very graphic interface."
"Any tool will do diagramming but I think the ability to put the stuff up in a graphical fashion, then think about it, and keep things consistent is what's valuable about it. It's too easy when you're using other methods to not have naming consistent standards and column consistent definitions, et cetera."
"We use the Forward and Reverse Engineering tools to help us speed things up and create things that would have to be done otherwise by hand. E.g., getting a database into a data model format or vice versa."
"This application does a lot of things, as do competitor products, but the main reason to go with this product was the ability to create many automations, where we can improve our work and our process."
"The data modeling and reverse engineering features are most important to us."
"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 are able to document the data lineage and data flows of our data from one system to another."
"The most important features are logical and physical models that we can compare and develop. Also, the Data Dictionary can be created out of your studio. Finally, database schemas help understand the logic that's behind the scene, behind the SQL tables. Especially when there are a lot of them, the schemas help everyone understand the business processes."
"It does the job."
"Developing new dimensional models; for the data we're hosting, dimensional modeling is more useful."
"We found a lot of duplication, a lot of non-conformity in the way our databases were designed. By identifying these situations, we're able to go back in and try to create a more standardized solution."
"The erwin Data Modeler is quite complex to use."
"I still use Visio for conceptual modeling, and that's mainly because it is easier to change things, and you can relax some of the rules. DM's eventual target is a database, which means you actually have to dot all the Is and cross all the Ts, but in a conceptual model, you don't often know what you're working with. So, that's probably a constraint with erwin. They have made it a lot easier, and they've done a lot, but there is probably still room for improvement in terms of the ease of presentation back to the business. I'm comparing it with something like Visio where you can change colors on a box, change the text color and that sort of stuff, and change the lines. Such things are a whole lot easier in Visio, but once you get a theme organized in erwin, you can apply that theme to all of the objects. So, it becomes easier, but you do have to set up that theme."
"I would like to have more data sources from other, different vendors. In recent years, the vendor has reduced the number of data sources, and I would like to have more data sources for every brand. For example, with Oracle, I would like to have compatibility for many versions, including old ones, not just the most recent."
"The report generation has room for improvement. I think it was version 8 where you had to use Crystal Reports, and it was so painful that the company I was with just stayed on version 7 until version 9 came out and they restored the data browser. That's better than it was, but it's still a little cumbersome. For example, you run it in erwin, then export it out to Excel, and then you have to do a lot of cosmetic modification. If you discover that you missed a column, then you would have to rerun the whole thing. Sometimes what you would do is just go ahead and fix it in the report, then you have to remember to go back and fix it in the model. Therefore, I think the report generation still could use some work."
"We are planning to move, in 2021, into their server version, where multiple data modelers can work at the same time and share their models. It has become a pain point to merge the models from individual desktops and get them into a single data model, when multiple data modelers are working on a particular project. It becomes a nightmare for the senior data modeler to bring them together, especially when it comes to recreating them when you want to merge them."
"The erwin ETL functionality has room for improvement when it comes to mapping databases with a classic entity-relationship model to a data warehouse model."
"The Bulk Editor needs improvement. If you had something that was a local model to your local machine, you could connect to the API, then it would write directly into the repository. However, when you have something that is on the centralized server, that functionality did not work. Then, you had to export out to a CSV and upload up to the repository. It would have been nice to be able to do the direct API without having that whole download and upload thing. Maybe I didn't figure it out, but I'm pretty sure that didn't work when it was a model that sat on a centralized repository."
"I would like the solution to be more user-friendly to deploy."
"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."
"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."
"What I would like to see improved is the reliability of the releases, releases that are a little less buggy."
"I would like to upload, a database with about 3,000 tables. It takes so much time and, finally, it freezes the whole solution so that I actually cannot work with that environment. For the data warehouse, it's fine because I have 20 or 30 tables. It works fine. But, when I reverse-engineer the database with 3,000 tables, it freezes and it's hard to upload and reverse-engineer such environments in ER/Studio."
"The number of options can be overwhelming at times. That is not necessarily a bad thing but for a newbie, it can be daunting."
"Sometimes our version is a little unstable. But I think this problem occurs because our version is old."
"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"
"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."
