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 principal feature that I liked is that the solution has a very graphic interface."

"The product itself is fantastic and it's about the only way to get an enterprise view of the data that you're designing."

"This product is the strongest data modeler on the market."

"They have a lot of features and the most up-to-date technology integration, which I haven't seen in other products."

"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."

"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 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 provides flexibility with the code. You can change the code as you want. Basically, you can change SQL based on what's best for your project."

More erwin Data Modeler pros

"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."

"Central repository holding single version of truth."

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

"The initial setup is easy."

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

"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."

More iServer pros

Cons

"I would like to see improved reporting and, potentially, dashboards built on top of that. Right now, it's a little manual. More automated reporting and dashboard views would help because currently you have to push things out to a spreadsheet, or to HTML, and there aren't many other options that I know of. I would like to be able to produce graphs and additional things right in the tool, instead of having to export the data somewhere else."

"I would like to see more support for working with the big-data world. It would be good if they were able to dynamically support big-data platforms, other than Hive and Teradata."

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

"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."

"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."

"The price should be reduced."

"Complete Compare is set up only to compare properties that are of interest to us, but some of the differences cannot be brought over from one version of the model to another. This is despite the fact that we are clicking to bring objects from one place to another. Therefore, it's hard to tell at times if Complete Compare is working as intended without having to manually go into the details and check everything. If it could be redesigned to a degree where it is easier to use when we bring things over from one site to another and be sure that it's been done correctly, that would be nice to have. We would probably use the tool more often if the Complete Compare were easier to use."

"The navigation is a little bit of a challenge. Moving around the model is painful because it doesn't follow the Windows model today."

More erwin Data Modeler cons

"Cannot see which activities are control activities."

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

"It runs relatively slowly."

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

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

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

"I haven't used this solution long enough to know what areas could be improved."

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

More iServer cons

Pricing and Cost Advice

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

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

"Likewise, the solution is a little pricey."

"The pricing of the solution is cheap. I rate the pricing a five out of ten."

"There is either a one-year or three-year license. It is not a pay-as-you-go license like a SaaS solution. It’s more of a traditional licensing. They are a little bit on the pricier side."

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

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

"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

"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 solution is cheaper than its competitors."

"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 product has a moderate pricing."
