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

"I love the way erwin Data Modeler creates data models and presents them for our users."

"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 the only meaningful way to do any data modeling."

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

"Forward engineering, DDL generation, reverse engineering, and reporting are the most valuable features of the solution."

"It saves a lot of development time, and I think we are saving from two weeks to one month annually."

"The accuracy and speed of the solution in transforming complex designs into well-aligned data sources make the cost of the tool worth it."

"The solution's ability to compare and synchronize data sources with data models is fantastic."

More erwin Data Modeler pros

"Good and effective reporting features, which help in decision making."

"This is a flexible tool compared to some other solutions."

"The solution has wide use within Microsoft products. The integration with Microsoft products, and, in particular, Microsoft Office, is great."

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

"The initial setup is easy."

"The product has a valuable customized model."

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

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

More iServer pros

Cons

"The reverse engineering in Oracle Databases needs improvement, as there are issues."

"The solution's reporting side needs to be improved."

"Sometimes when I want to open the attribute editor, it stops working and the whole application freezes."

"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."

"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."

"I would like to see more support for working with the big-data world. There are so many new databases evolving and it's very hard for them to keep up with all of the new technologies. It would be good if they were able to dynamically support big-data platforms, other than Hive and Teradata."

"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."

"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."

More erwin Data Modeler cons

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

"The one issue is that if you want to import predefined work, you need to put the licensing model in. So if you wanted to import work that was done before, you then need to buy a separate product for that."

"The modelling needs improvement, specifically forecasting capabilities and scenarios."

"The migration tool needs to be included in the main package, and not as a separate license."

"There could be features for process mining, process simulation, and analytics."

"We could allocate permissions to use only specific components to the users rather than the entire instance."

"The performance is slow, which is something that should be improved."

"Requirements management needs to be improved."

More iServer cons

Pricing and Cost Advice

"Likewise, the solution is a little pricey."

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

"The price should be lower in order to be on the same level as its competitors."

"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."

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

"I don't specifically know what we're paying now. About three years ago, in another organization, I have this memory of 6,000 AUD a seat or something like that, but I am not sure. In the mid-2000s, it was something like 1,200 AUD a seat. I get the impression that there was a price jump when it was spun off from CA as a separate company, which is understandable, but it could sometimes be a barrier in some organizations picking it up. I haven't talked to erwin people yet, but I'm going to suggest to them that they could perhaps think of having an entry-level product that is priced a bit lower, and then, you can buy the extra suite."

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

"It is not a very expensive solution. Only the licensing and maintenance fee needs to be paid."

More erwin Data Modeler pricing and cost advice

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

"The solution is cheaper than its competitors."

"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 product has a moderate pricing."

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

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