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

"This tool is beneficial to any organization as it is foundational; there is no better way than this, and it is a must-have for every organization, whether large or small."

"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."

"I have used most of the modeling tools available, but I found that erwin Data Modeler is the most suitable data modeling tool in our current industry."

"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."

"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."

"It is a scalable solution...The technical support team is fine."

"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."

"The ability to collaborate between different members across the organization is the most valuable feature. It gives us the ability to work on the same model, regardless of where we are physically."

More erwin Data Modeler pros

"I have to think less with this solution. It's simple."

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

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

"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."

"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."

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

"We like the governance."

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

More iServer pros

Cons

"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."

"This is a very complex product."

"I would like the solution to be more user-friendly to deploy."

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

"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."

"As erwin Data Modeler files get larger, the response time really slows down, and when I have multiple files open I sometimes get a glitch where a lot of the text fields get solid black and the first eight characters of column names might be blacked out with a rectangle."

"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."

"Although Quest Software has made tremendous strides in recent years, they need to evolve more in the big data arena; erwin Data Modeler could use a little more work when it comes to big database designs."

More erwin Data Modeler cons

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

"It runs relatively slowly."

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

"There can be some performance issues using the solution that should be improved. When you make modifications modify to files there are embedded data within that can take a while to process."

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

"More visualization techniques and ways to report the data might be helpful."

More iServer cons

Pricing and Cost Advice

"The solution is expensive."

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

"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."

"The price should be lower in order to be on the same level as its competitors."

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

"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."

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

More erwin Data Modeler pricing and cost advice

"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."

"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."
