Data modeling has transformed regulatory reporting and collaboration across cloud environments

In erwin Data Modeler, areas that have room for improvement include performance improvements. I see that large models sometimes cause it to be slow when opening. Impact analysis can lag as well. Version control is another aspect. If we have developed a current version, it is not integrated with Git where we can easily compare different versions. UI modernization is also something we cannot utilize as it is primarily for development. Additionally, cloud-specific optimizations are needed when it comes to Snowflake or Databricks. When it comes to AI aspects, auto-suggestions for normalization or identifying primary, foreign, or surrogate keys are areas that can be improved.

Quotes from Members

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

Pros

"The biggest lesson I have learned from erwin is the old cliche, that a picture is worth a thousand words, and when a person asks for a set of tables and they actually see that diagram visually, it really assists in any meeting that you will have."

"Overall, erwin DM's support for Snowflake is very good."

"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."

"The data lineage feature is very valuable."

"The most valuable features are being able to visualize the data in the diagrams and transform those diagrams into physical database deployments. These features help, specifically, to integrate the data. When the source data is accumulated and modeled, the target model is in erwin and it helps resolve the data integration patterns that are required to map the data to accommodate a model."

"It's a safeguard for me because I'm always concerned that somebody is free handing it and will forget a key coming from the parent. The migrating keys are a great feature. Identifying relationships, non-identifying relationships, and being visually right there to understand the differences are great features. erwin is key to being able to visually understand whatever the customer is requesting. They'll give you words on a paper, but once they can actually view it as a picture, it really comes to life. The data comes to life to where they understand exactly what they're asking for."

"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."

"In my previous company, there we had a really large return on investment from using erwin."

More erwin Data Modeler pros

"This flexibility is the most helpful part in the standard version."

"We like the governance."

"The solution is easily modified to suit your needs."

"The most valuable feature is its reporting capability. It offers various packages for different types of reports, such as business and project management reporting packs."

"iServer has valuable features for workflow and document management."

"iServer is a very flexible platform for defining your own enterprise architecture model."

"Process modelling through object creation and management is beneficial as a very effective change management of processes at the object level, because if you need to modify a process and it will impact other processes as well, the object changed automatically changes in other processes as well."

"iServer is a solution that helps catalog enterprise architect solutions and catalog information."

More iServer pros

Cons

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

"It is not a very stable solution. I rate the stability five out of ten."

"I would rate the visualization feature in erwin Data Modeler a six out of ten because the visualization is somewhat poor and some of the features are not user-friendly."

"What I did not like was that sometimes while I was creating relations, I was not getting errors. The errors only appeared when I tried to upload the model into a new database, which took a lot of time because I was creating a model, reproducing XML, and then trying to add the XML in the database."

"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."

"I find the UI very clunky and very difficult to use."

"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."

More erwin Data Modeler cons

"Cannot see which activities are control activities."

"It runs relatively slowly."

"Setting up the Portal was very complex. We required a lot of support from the vendor."

"Enhancing integration options with ERP or ITSM-related solutions for triggering automated requests for process definitions, changes, and tracking them in the iServer."

"Requirements management needs to be improved."

"Overall, I would say that it's a poor man's EA repository. It seems like a good idea, but doesn't really work in practice."

"It's a very simple tool, which makes me concerned with the performance."

"iServer should invest in enhancing the capabilities of the embedded drawing tool, draw.io."

More iServer cons

Pricing and Cost Advice

"Price-wise, erwin Data Modeler is okay. You can purchase a single license and it is not very expensive."

"I wish it wasn't so expensive. I would love to personally buy a copy of my own and have it at home, because the next job that I'm looking at is probably project management and I might not have access to the tool. I would like to keep my ability to use the tool. Therefore, they should probably have a pricing for people like me who want to just use the solution as an independent consultant, trying to get started. $3,000 is a big hit."

"There are no costs in addition to the standard licensing fees."

"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."

"We've continued to use the product for many years and compared it with others on the market. The pricing is reasonable considering what the solution offers and what we pay. There are cheaper tools, but they may not be as robust and easy to use, so it's worth the money."

"The solution is expensive."

"Pricing is very high compared to any other product."

"The tool is expensive."

More erwin Data Modeler pricing and cost advice

"Aim for the exact number of people who shall define/review approve and view the processes, as it will impact the cost."

"The solution is cheaper than its competitors."

"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."

"It's about 13K to set up and 9K for the license for three months. I think it's about 20K a year, but we haven't firmed up on pricing yet because the price depends on how long we commit to the solution."

"The price of iServer is reasonable compared to other solutions."

"The product has a moderate pricing."
