Data modeling has enabled end-to-end designs and has improved collaboration between teams
Areas of erwin Data Modeler that I think could be improved or enhanced include a few things. I have not worked in erwin for the past four to five years, but based on my 20 years of career experience, I worked with erwin one or two years on an earlier project and currently am working with it again. Based on my overall 20 years of career experience, I have worked with erwin modeling for four to five years. I am not a master of the tool, but I cannot identify significant flaws. The price should be reduced. That could be one area of improvement. Additionally, the licensing system could be enhanced. In our current project, there are five licenses within the business. If anyone is moving to erwin, the other person cannot enter the erwin solution. There should be a message indicating that five persons are involved in erwin, and you cannot use it at that time. However, that is a minor issue.

Quotes from Members

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

Pros

"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 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 generation of DDL saved us having to write the steps by hand. You still had to go in and make some minor modifications to make it deployable to the database system. However, for the data lineage, it is very valuable for tracing our use of data, especially personal confidential data through different systems."
"The principal feature that I liked is that the solution has a very graphic interface."
"The product allows us to reuse entities and attributes."
"The most valuable features are the ability to reverse engineer and do model comparison. With the reverse engineering, I can understand the databases from third-party products. With the model comparison, I can track the differences between two versions of the same database."
"We use the Forward and Reverse Engineering tools to help us speed things up and create things that would have to be done otherwise by hand. E.g., getting a database into a data model format or vice versa."
"Currently in the market, there is no competitor to erwin Data Modeler; everything is very powerful, such as performing reverse engineering from an existing database and deploying that on Databricks or Snowflake."
"iServer is a very flexible platform for defining your own enterprise architecture model."
"iServer is a solution that helps catalog enterprise architect solutions and catalog information."
"This is a flexible tool compared to some other solutions."
"We like the governance."
"The most valuable features of iServer are the integration with Microsoft Office and the interface is similar to Microsoft applications making them easy to use."
"The solution has wide use within Microsoft products. The integration with Microsoft products, and, in particular, Microsoft Office, is great."
"It has helped having data lineage in the business cluster, which is used as control artifacts."
"I have to think less with this solution. It's simple."
 

Cons

"I would like the solution to be more user-friendly to deploy."
"Sometimes when I want to open the attribute editor, it stops working and the whole application freezes."
"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."
"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."
"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."
"The modeling product itself is far and above anything else that I've seen on the market. There are certain inconsistencies when it comes to keeping up with other platforms' databases in the reverse-engineering process. It should also support more database platforms."
"One of the best aspects of the tool is its reverse engineering capability."
"The price should be reduced."
"I haven't used this solution long enough to know what areas could be improved."
"We could allocate permissions to use only specific components to the users rather than the entire instance."
"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 performance is slow, which is something that should be improved."
"The migration tool needs to be included in the main package, and not as a separate license."
"Requirements management needs to be improved."
"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."
 

Pricing and Cost Advice

"Price-wise, erwin Data Modeler is okay. You can purchase a single license and it is not very expensive."
"The price should be lower in order to be on the same level as its competitors."
"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 tool is expensive."
"The pricing of the solution is cheap. I rate the pricing a five out of ten."
"The primary reasons that erwin was selected were that it was much more affordable for us [than Embarcadero] and it was easily maintainable."
"I don't specifically know what we're paying now. About three years ago, in another organization, I have this memory of 6,000 AUD a seat or something like that, but I am not sure. In the mid-2000s, it was something like 1,200 AUD a seat. I get the impression that there was a price jump when it was spun off from CA as a separate company, which is understandable, but it could sometimes be a barrier in some organizations picking it up. I haven't talked to erwin people yet, but I'm going to suggest to them that they could perhaps think of having an entry-level product that is priced a bit lower, and then, you can buy the extra suite."
"erwin Data Modeler by Quest is an expensive 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."
"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 solution is cheaper than its competitors."
"The price of iServer is reasonable compared to other solutions."
