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

"We can create mappings in erwin and possibly data dictionaries."

"Drag-and-drop data modeling and reverse engineering out of databases are the most valuable features of erwin Data Modeler by Quest."

"The visual data models for helping to overcome data source complexity and enabling understanding and collaboration around maintenance and usage are excellent. A picture speaks 1,000 words. Seeing a picture that shows you how the data relates to each other helps you better understand what the data is and how to use it. Pairing that information with a dictionary, which has the definitions of the tables and columns or the entities and attributes, ensures that the users understand what the data is so that they can use it best and most successfully."

"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."

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

"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."

"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."

"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."

More erwin Data Modeler pros

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

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

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

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

"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."

"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 solution that helps catalog enterprise architect solutions and catalog information."

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

Cons

"erwin generally fails to successfully reverse engineer our Oracle Databases into erwin data models. The way that they are engineered on our side, the syntax is correct from an Oracle perspective, but it seems to be very difficult for erwin to interpret. What I end up doing is using Oracle Data Modeler to reverse engineer into the Oracle data model, then forward engineer the DDL into an Oracle syntax, and importing that DDL into erwin in order to successfully bring in most of the information from our physical data models. That is a bit of a challenge."

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

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

"It has a very steep learning curve, limited support for NoSQL or streaming systems, and potentially a high licensing cost."

"I would like the solution to be less rigid in terms of its theory."

"The erwin Data Modeler is quite complex to use."

"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 solution's model mark could be better because it crashes sometimes."

More erwin Data Modeler cons

"Requirements management needs to be improved."

"Cannot see which activities are control activities."

"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."

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

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

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

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

More iServer cons

Pricing and Cost Advice

"The solution is expensive."

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

"Likewise, the solution is a little pricey."

"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."

"Though the solution is not cheap, it's worth the money."

"The tool is expensive."

"The primary reasons that erwin was selected were that it was much more affordable for us [than Embarcadero] and it was easily maintainable."

"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

"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."

"The product has a moderate pricing."

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

"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."
