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

"Erwin is by far the best tool I've ever used."
"It is an invaluable tool for us; it has been part of our data governance process in regards to database design for at least 15 years."
"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."
"The product lets us import different types of models from various databases."
"It has made a lot of difference in terms of naming standards, processes around our metadata, and the schema in which we create a database."
"It is the only meaningful way to do any data modeling."
"The accuracy and speed of the solution in transforming complex designs into well-aligned data sources makes the cost of the tool definitely worth it."
"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."
"Central repository holding single version of truth."
"Process modelling through object creation and management is beneficial as a very effective change management of processes at the object level, because if you need to modify a process and it will impact other processes as well, the object changed automatically changes in other processes as well."
"It has helped having data lineage in the business cluster, which is used as control artifacts."
"iServer is a very flexible platform for defining your own enterprise architecture model."
"The initial setup is easy."
"This is a flexible tool compared to some other solutions."
"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."
"I love how there are no milestone swimlanes."
 

Cons

"I would like the solution to be more user-friendly to deploy."
"There are some bugs here and there. The default code that comes with the customizable packages is a bit buggy on some platforms such as PostgreSQL."
"I would like to see the reporting capabilities be more dynamic and more inclusive of information. The API is very sparsely understood by people across the user community."
"It is not a very stable solution. I rate the stability five out of ten."
"The UI in erwin Data Modeler can be improved significantly because when any new person opens the tool, all the toolbars are kept open with many tools in view, making it appear chunky."
"One of the things I've been talking to the erwin team about through the years is that every data model should have the ability to be multi-language... When I was working at Honda, it became very difficult to work with the Japanese teams using just one model. You can have two models, one in English and one in Japanese, but that means you have to keep the updates back and forth, and that always increases the risk of something not being updated."
"Some Source official systems give us DDLs to work with and they have contents not required to be part of the DDL before we reverse engineer in the erwin DM."
"The interface must be improved."
"Setting up the Portal was very complex. We required a lot of support from the vendor."
"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 performance is slow, which is something that should be improved."
"Cannot see which activities are control activities."
"More visualization techniques and ways to report the data might be helpful."
"I do not find it friendly to use."
"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."
 

Pricing and Cost Advice

"The primary reasons that erwin was selected were that it was much more affordable for us [than Embarcadero] and it was easily maintainable."
"The pricing of the solution is cheap. I rate the pricing a five out of ten."
"Likewise, the solution is a little pricey."
"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 solution is expensive."
"erwin Data Modeler by Quest is an expensive solution."
"The tool is expensive."
"The price should be lower in order to be on the same level as 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."
"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."
"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."
"The price of iServer is reasonable compared to other solutions."
