Streamline data modeling and automate network changes for increased efficiency

The initial setup depends on the tool if you are using the data model environment. Stopping the server could be complex and require strong expertise. If you have everything set up and configured, Erwin is straightforward. You can deploy it in a few hours. In our case, it took a couple of months to address internal conditions, assign machines, and set up everything for the services. I rate the initial setup a six out of ten, where one is difficult and ten is easy.

Useful for creating build-outs and architecture views, but requires a publisher add-on for some detailed reports

I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The product allows us to reuse entities and attributes."

"The most valuable feature is the physical or visual representation of the database, showing the tables, the columns, the foreign keys, and the ability to generate DDL, so you can physically implement databases."

"It supports a wide variety of databases, including the latest ones. We have chosen to go for a cloud-based database, and it supports that, which is very useful."

"When you're getting down to the database level, where you're building a design and you're creating DDL out of it, or you're going in the other direction where you're reaching into system catalogs and bringing things back, that starts to really require specialization. Visio isn't going to reverse-engineer that for you. Those features in erwin are valuable."

"The visual data models for helping to overcome data source complexity and enabling understanding and collaboration around maintenance and usage are excellent. A picture speaks 1,000 words. Seeing a picture that shows you how the data relates to each other helps you better understand what the data is and how to use it. Pairing that information with a dictionary, which has the definitions of the tables and columns or the entities and attributes, ensures that the users understand what the data is so that they can use it best and most successfully."

"Quest can create conceptual and physical data models to facilitate effective communication between business and IT. It can also integrate expertise from various engineering and database systems within your organization to enhance data management and administration."

"The most valuable features are the ability to reverse engineer and do model comparison. With the reverse engineering, I can understand the databases from third-party products. With the model comparison, I can track the differences between two versions of the same database."

"It is a scalable solution...The technical support team is fine."

More erwin Data Modeler pros

"It is useful for creating build-outs and architecture views and for publishing reports and stuff like that for different programs."

"It has good end-to-end metamodel interrelationships."

Cons

"In terms of improvements, support could have been better in terms of installation, especially of workgroups. We struggled quite a bit to get it up and running. Collaboration could have been better from an installation perspective, but it is trivial as compared to what we use it for. Other than that, I don't have much feedback. It works pretty well, and the fact that we've been using it for more than a decade shows that it is quite solid."

"erwin is not as robust as a data warehousing project I've been on in the past."

"Some Source official systems give us DDLs to work with and they have contents not required to be part of the DDL before we reverse engineer in the erwin DM. Therefore, we manually make changes to those scripts and edit them, then reverse-engineer within the tool. So, it does take some time to edit these DDL scripts generated by the source operational systems. What I would suggest: It would be helpful if there were a place within the erwin tool to import the file and automatically eliminate all the unnecessary lines of code, and just have the clean code built-in to generate the table/data model."

"I'd really like to see the PDF function become available. It would make my life much easier than what it is at the moment because whenever I need to collaborate with people that do not have erwin, I have to go through the wonkiness of going to Word and then save it from Word into PDF. There's a lot of differences between erwin 4.4 and 2020."

"It would be nice to have it on the Linux platform, not just Windows. If they can support Linux, there would be a huge market for it."

"I love the product. I love the ability to get into the code, make it automated, and make it do what I want. I would like to see them put some kind of governance over the ability to make changes to the mart tables with the API, so that instead of just using the modeler's rights to a table -- it has a separate set of rights for API access. That would give us the ability to put governance around API applications. Right now a person with erwin and Excel/VBA has the ability to make changes to models with the API if they also have rights to make changes to the model from erwin. It's a risk."

"I would like the solution to be more user-friendly to deploy."

"As someone who has used it for a long time, I have seen stability vary from version to version."

More erwin Data Modeler cons

"I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool."

"They need to add reports that show the enterprise architecture perspectives, and the dashboards should be comfortable for the senior enterprise architects so that they can view the complete landscape."

Pricing and Cost Advice

"Though the solution is not cheap, it's worth the money."

"erwin is expensive compared to other solutions. We are paying almost $6,000 per seat a month."

"erwin Data Modeler by Quest is an expensive solution."

"There are two license options and the pricing is reasonable."

"An issue right now would be that erwin doesn't have a freely available browser (that I am aware of) for people who are not data modelers or data engineers that a consumer could use to look at the data models and play with it. This would not be to make any changes, but just to visually look at what exists. There are other products out there which do have end user browsers available and allow them to access data models via the data modeling tool."

"The solution is expensive."

"The price of erwin Data Modeler is very expensive, in particular for this part of the world."

"erwin has this option where you pay a one-time fee and you have the license for six years, which makes sense because I don't upgrade my database engine every other year. I have an application that depends on it. This is something weird about PowerDesigner. There are no additional costs beyond the standard licensing fee."

More erwin Data Modeler pricing and cost advice

"I don't remember the price. It is a different cost for just buying it, and then you have a maintenance cost, which you need to renew every year."
