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

"It reduces monthly savings by hundreds of thousands of dollars. Think about a company like Costco and all of the points of sale systems in Costco, all of the systems, the applications, but if all the applications in Costco all had their own data model, trying to integrate those, upgrade them and manage their different versions of the same model throughout the store, is an absolute nightmare. It's phenomenally expensive. This helps reduce that cost significantly. I'm talking on the orders of hundreds of thousands of dollars."

"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."

"This tool is beneficial to any organization as it is foundational; there is no better way than this, and it is a must-have for every organization, whether large or small."

"One of the best aspects of the tool is its reverse engineering capability."

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

"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."

"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 ability to collaborate between different members across the organization is the most valuable feature. It gives us the ability to work on the same model, regardless of where we are physically."

More erwin Data Modeler pros

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

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

"The product has a valuable customized model."

"I have to think less with this solution. It's simple."

"Tech support is very responsive. They solved issues within a prompt response time."

"It has helped having data lineage in the business cluster, which is used as control artifacts."

"Integrating the Microsoft documents to the product and visualization matrix where we can see the end-to-end relationship of the network is of great importance to our company."

"There were lots of different requirements, and collaboration and review is one of the biggest things. There is also Office 360 integration, and there's flexibility to use it as a database as well."

More iServer pros

Cons

"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."

"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."

"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."

"One of the things I've been talking to the erwin team about through the years is that every data model should have the ability to be multi-language... When I was working at Honda, it became very difficult to work with the Japanese teams using just one model. You can have two models, one in English and one in Japanese, but that means you have to keep the updates back and forth, and that always increases the risk of something not being updated."

"The price should be reduced."

"One of the best aspects of the tool is its reverse engineering capability."

"There is a lack of local support in the China region."

"As erwin Data Modeler files get larger, the response time really slows down, and when I have multiple files open I sometimes get a glitch where a lot of the text fields get solid black and the first eight characters of column names might be blacked out with a rectangle."

More erwin Data Modeler cons

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

"It definitely needs help to improve the visual aspect of the solution."

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

"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."

"It runs relatively slowly."

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

"There can be some performance issues using the solution that should be improved. When you make modifications modify to files there are embedded data within that can take a while to process."

"The product is more expensive than Spark."

More iServer cons

Pricing and Cost Advice

"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."

"Likewise, the solution is a little pricey."

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

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

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

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

"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."

More erwin Data Modeler pricing and cost advice

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

"The product has a moderate pricing."

"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."

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

"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."
