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."

"What has been useful, I have been able to reverse engineer our existing data models to document explicitly referential integrity relationships, primary/foreign keys in the model, and create ERDs that are subject area-based which our clients can use when working with our databases. The reality is that our databases are not explicitly documented in the DDL with primary/foreign key relationships. You can't look at the DDL and explicitly understand the primary/foreign key relationships that exist between our tables, so the referential integrity is not easily understood. erwin has allowed me to explicitly document that and create ERDs. This has made it easier for our clients to consume our databases for their own purposes."

"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."

"We use the macros with naming standards patterns, domains, datatypes, and some common attributes. As far as other automations, a feature of the Bulk Editor is mass updates. When it sees something is nonstandard or inaccurate, it will export the better data out. Then, I can easily see which entities and attributes are not inline or standard. I can easily make changes to what was uploaded to the Bulk Editor. When taking on a new project, it can save you about a half a day on a big project across an entire team."

"The product allows us to reuse entities and attributes."

"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."

"We find that its ability to generate database code from a model for a wide array of data sources cuts development time. The ability to create one model in your design phase and then have it generate DDL code for Oracle or Teradata, or whichever environment you need is really nice. It's not only nice but it also saves man-hours of time. You would have to take your design and just type in manually. It has to take days off out of the work."

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

More erwin Data Modeler pros

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

"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."

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

"The initial setup is easy."

"Good and effective reporting features, which help in decision making."

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

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

"The product has a valuable customized model."

More iServer pros

Cons

"Erwin Data Modeler is a good product, but I recently experienced a problem where I was not able to open an erwin Data Modeler file because its version had automatically changed."

"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."

"As someone who has used it for a long time, I have seen stability vary from version to version."

"It does not have a cloud application."

"The interface must be improved."

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

"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."

"erwin is not as robust as a data warehousing project I've been on in the past."

More erwin Data Modeler cons

"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."

"The product is more expensive than Spark."

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

"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."

"The migration tool needs to be included in the main package, and not as a separate license."

"Requirements management needs to be improved."

More iServer cons

Pricing and Cost Advice

"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."

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

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

"The tool is expensive."

"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."

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

"Pricing is very high compared to any other product."

More erwin Data Modeler pricing and cost advice

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

"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."

"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."
