Structured data modeling has accelerated AI-driven customer insights and cloud migrations
One feature that I wish erwin Data Modeler could improve is how user experience becomes much more intuitive, particularly when navigating large models or reviewing changes over time. Easier model exploration, clear visibility into differences between versioning, and practical documentation for use cases could help users work more effectively. I would also welcome the capability to have integrations with other platforms where the blueprint can be exchanged seamlessly without having to do an export and an import process. This would also help in bringing in the AI capability, which can assist in better positioning erwin Data Modeler not just as a tool for designing and documenting data models, but also as part of the broader data architecture and development lifecycle. Regarding erwin Data Modeler's AI capabilities, there is an opportunity to enhance user experience from a governance standpoint, supporting tracking model changes, maintaining audit trails, and managing role-based access while enforcing consistent modeling standards across teams would be a value-added feature, particularly in a large-scale environment. It would also be beneficial to have better visibility into sensitive data attributes and their relationships to govern the requirements, including privacy and access controls. As organizations increasingly adopt AI development, integrating these governance and security considerations into the model and implementing workflows could also help teams work more effectively while maintaining appropriate oversights. Regarding erwin Data Modeler's AI capabilities, there is still room for improvement regarding accuracy and reliability of output as large language models need clear instructions. There is room for growth because business requirements keep changing, relationships keep changing, and the capability to identify inconsistencies, missing relationships, or incorrect definitions are areas where it can improve. This is not to say that the current features are not good enough; they are excellent, but there is definitely room to catch up on AI changes. This is particularly important when modeling using blueprints inputted via AI assistant programs, and when an error occurs in the original model, it could carry over into a generated implementation. That is one of the experiences I faced when working on a project for the Adobe Experience Platform. I experience some integration failures often with erwin Data Modeler, but there is documentation that we can look up that helps resolve these bugs. The new integration changes on our end sometimes pose a challenge, but the process is generally seamless, and the support available makes it much easier for us to troubleshoot any challenges we might face. Managing data across different environments, such as traditional databases, NoSQL, big data, and cloud platforms with erwin Data Modeler presents the biggest challenge of translating from a traditional database to a non-SQL database. These challenges are primarily based on the structure of the data model. Overall, there are external tools that help us in translating that, and I would love to add this as a feature to simplify the process and reduce the complexity of using external extensions for making those changes or guiding through the process.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is the only meaningful way to do any data modeling."
"Using erwin Data Modeler has positively impacted my organization by improving data consistency and standardization, reducing development effort, enhancing data governance, fostering better collaboration, and minimizing risk and rework."
"Any tool will do diagramming but I think the ability to put the stuff up in a graphical fashion, then think about it, and keep things consistent is what's valuable about it. It's too easy when you're using other methods to not have naming consistent standards and column consistent definitions, et cetera."
"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."
"They have a lot of features and the most up-to-date technology integration, which I haven't seen in other products."
"In my previous company, there we had a really large return on investment from using erwin."
"The solution is good for organizing the data and the scripting part is very powerful. It's easy to create technical scripts for models."
"One of the best aspects of the tool is its reverse engineering capability."
"Tech support is very responsive. They solved issues within a prompt response time."
"Good and effective reporting features, which help in decision making."
"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."
"This flexibility is the most helpful part in the standard version."
"I love how there are no milestone swimlanes."
"iServer is a solution that helps catalog enterprise architect solutions and catalog information."
"We like the governance."
"From September 2014 through January 2015, I received help from the tech support staff of iServer, who were very prompt and almost instantaneously responded, and if it was something difficult, they brought three to four people to talk with me and then solved the problem within minutes."
 

Cons

"We find erwin DM less valuable creating initial drafts and reverse-engineering databases and there are still a lot of extensions to the scripting language that are not included with the erwin product."
"The price should be reduced."
"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."
"Sometimes when I want to open the attribute editor, it stops working and the whole application freezes."
"The solution's model mark could be better because it crashes sometimes."
"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."
"The solution only works with one server and one database, so I don't think it's scalable enough."
"I would rate the visualization feature in erwin Data Modeler a six out of ten because the visualization is somewhat poor and some of the features are not user-friendly."
"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."
"iServer should invest in enhancing the capabilities of the embedded drawing tool, draw.io."
"The modelling needs improvement, specifically forecasting capabilities and scenarios."
"Customer service can be improved as the vendor is based in UK. Having regional support could improve time and communications."
"There could be features for process mining, process simulation, and analytics."
"It's a very simple tool, which makes me concerned with the performance."
"More visualization techniques and ways to report the data might be helpful."
"It definitely needs help to improve the visual aspect of the solution."
 

Pricing and Cost Advice

"Pricing is very high compared to any other product."
"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."
"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."
"There are no costs in addition to the standard licensing fees."
"erwin Data Modeler by Quest is an expensive solution."
"Though the solution is not cheap, it's worth the money."
"The solution 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."
"The price of iServer is reasonable compared to other solutions."
"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."
"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 product has a moderate pricing."
"The solution is cheaper than its competitors."
