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 solution’s code generation ensures accurate engineering of data sources, as there is no development time. Code doesn't even have to be reviewed. We have been using this solution for so long and all the code which has been generated is accurate with the requirements. Once we generate the DDLs out of the erwin tools, the development team does a quick review of the script line by line. They will just be running the script on the database and looking into other requirements, such as the index. So, there is less effort from development side to create tables or build a database."
"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."
"Forward engineering, DDL generation, reverse engineering, and reporting are the most valuable features of the solution."
"Currently in the market, there is no competitor to erwin Data Modeler; everything is very powerful, such as performing reverse engineering from an existing database and deploying that on Databricks or Snowflake."
"I compare erwin Data Modeler with other solutions such as ER/Studio and believe it stands out as an enterprise-grade data modeling tool capable of serving different industries, such as finance, healthcare, and telecom."
"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."
"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 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 is easily modified to suit your needs."
"iServer is a solution that helps catalog enterprise architect solutions and catalog information."
"It has helped having data lineage in the business cluster, which is used as control artifacts."
"The product has a valuable customized model."
"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."
"iServer is a very flexible platform for defining your own enterprise architecture model."
"This is a flexible tool compared to some other solutions."
"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."
 

Cons

"The erwin Data Modeler is quite complex to use."
"I am not so happy with its speed. Sometimes, it can have problems with connections."
"I would like to see the ability to support more NoSQL platforms more quickly. In addition, enhancing the graphics to render more quickly would be beneficial for any user."
"I would like to have more data sources from other, different vendors. In recent years, the vendor has reduced the number of data sources, and I would like to have more data sources for every brand. For example, with Oracle, I would like to have compatibility for many versions, including old ones, not just the most recent."
"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."
"The solution's model mark could be better because it crashes sometimes."
"The solution only works with one server and one database, so I don't think it's scalable enough."
"In terms of new features, it would be great to have a cloud base. We should be able to put it on the cloud for better collaboration and data models sharing."
"I haven't used this solution long enough to know what areas could be improved."
"There could be features for process mining, process simulation, and analytics."
"The performance is slow, which is something that should be improved."
"The modelling needs improvement, specifically forecasting capabilities and scenarios."
"Setting up the Portal was very complex. We required a lot of support from the vendor."
"Requirements management needs to be improved."
"The product is more expensive than Spark."
"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."
 

Pricing and Cost Advice

"There are no costs in addition to the standard licensing fees."
"There are two license options and the pricing is reasonable."
"The price of erwin Data Modeler is very expensive, in particular for this part of the world."
"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."
"This company had bought the license for three years, and it's not an individual license. While you can buy a license for each individual, that would be very expensive. There is something called concurrent licenses where you can purchase licenses in bulk and 15 to 20 people can access the license and model. Concurrent licenses are scalable to the number of users and are proportional to the cost."
"The primary reasons that erwin was selected were that it was much more affordable for us [than Embarcadero] and it was easily maintainable."
"The price should be lower in order to be on the same level as its competitors."
"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."
"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."
"Aim for the exact number of people who shall define/review approve and view the processes, as it will impact the cost."
"The price of iServer is reasonable compared to other solutions."
"The product has a moderate pricing."
"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."
