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 is excellent in providing a visual representation of a database and can generate DDL for implementing changes. We use DDL for logical purposes to review with business people, ensuring they have the required fields for processing. We also use it as a data dictionary for the physical data model to understand all the purposes of the terms. This helps us map the logical and physical terms with the business definition to understand our data."

"My favorite feature of erwin Data Modeler is that we can export and import tables directly from the databases, and it is easy to map from table to table and column to column."

"It's important to create standard templates — Erwin is good at that — and you can customize them. You can create a standard template so that your models have the same look and feel. And then, anyone using the tool is using the same font and the same general layout. erwin's very good at helping enforce that."

"The logical model gives developers, as well as the data modelers, an understanding of exactly how each object interacts with the others, whether a one-to-many, many-to-many, many-to-one, etc."

"It provides flexibility with the code. You can change the code as you want. Basically, you can change SQL based on what's best for your project."

"When you're getting down to the database level, where you're building a design and you're creating DDL out of it, or you're going in the other direction where you're reaching into system catalogs and bringing things back, that starts to really require specialization. Visio isn't going to reverse-engineer that for you. Those features in erwin are valuable."

"I love the way erwin Data Modeler creates data models and presents them for our users."

"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."

More erwin Data Modeler pros

"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."

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

"The initial setup is easy."

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

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

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

"The product has a valuable customized model."

More iServer pros

Cons

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

"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."

"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 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 erwin Data Modeler is quite complex to use."

"There is a lack of local support in the China region."

"The Bulk Editor needs improvement. If you had something that was a local model to your local machine, you could connect to the API, then it would write directly into the repository. However, when you have something that is on the centralized server, that functionality did not work. Then, you had to export out to a CSV and upload up to the repository. It would have been nice to be able to do the direct API without having that whole download and upload thing. Maybe I didn't figure it out, but I'm pretty sure that didn't work when it was a model that sat on a centralized repository."

"The erwin ETL functionality has room for improvement when it comes to mapping databases with a classic entity-relationship model to a data warehouse model."

More erwin Data Modeler cons

"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."

"There are other solutions out there that have a better user interface."

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

"The performance is slow, which is something that should be improved."

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

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

"There could be features for process mining, process simulation, and analytics."

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

More iServer cons

Pricing and Cost Advice

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

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

"There are two license options and the pricing is reasonable."

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

"The price of erwin Data Modeler is very expensive, in particular for this part of the world."

"There are no costs in addition to the standard licensing fees."

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

More erwin Data Modeler pricing and cost advice

"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 product has a moderate pricing."

"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."

"The solution is cheaper than its competitors."

"Aim for the exact number of people who shall define/review approve and view the processes, as it will impact the cost."
