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

"Being able to point it to a database and then pull the metadata is a valuable feature. Another valuable feature is being able to rearrange the model so that we can display it to users. We are able to divide the information into subject areas, and we can divide the data landscape into smaller chunks, which makes it easier to understand. If you had 14 subject areas, 1,000 entities, and 6,000 columns, you can't quite understand it all at once. So, being able to have the same underlying model but only display portions of it at a time is extremely useful."

"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."

"We had some data integration projects, where we needed to integrate it for about 100 databases. Doing that manually is crazy; we can't do that. With erwin, it was much easier to identify which tables and columns could be used for the integration. That means a lot in terms of time and effort as well as my image to the customer, because they can see that we are providing value in a very short time."

"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."

"There is absolutely no problem with the stability."

"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 process of creating visual representations of data structures using erwin Data Modeler allows you to see everything you are doing, and you have visuals to see what you are going to do and what has been done so far."

"Another feature of erwin is that it can help you enforce your naming standards. It has little modules that you can set up and, as you're building the data model, it's ensuring that they conform to the naming standards that you've developed."

More erwin Data Modeler pros

"The solution is easily modified to suit your needs."

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

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

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

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

"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."

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

"The initial setup is easy."

More iServer pros

Cons

"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."

"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."

"The solution's model mark could be better because it crashes sometimes."

"I'd really like to see the PDF function become available. It would make my life much easier than what it is at the moment because whenever I need to collaborate with people that do not have erwin, I have to go through the wonkiness of going to Word and then save it from Word into PDF. There's a lot of differences between erwin 4.4 and 2020."

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

"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."

"It would be nice to have it on the Linux platform, not just Windows. If they can support Linux, there would be a huge market for it."

"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."

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."

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

"The product is more expensive than Spark."

"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."

"It runs relatively slowly."

"Requirements management needs to be improved."

More iServer cons

Pricing and Cost Advice

"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."

"An issue right now would be that erwin doesn't have a freely available browser (that I am aware of) for people who are not data modelers or data engineers that a consumer could use to look at the data models and play with it. This would not be to make any changes, but just to visually look at what exists. There are other products out there which do have end user browsers available and allow them to access data models via the data modeling tool."

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

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

"Likewise, the solution is a little pricey."

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

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

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

More erwin Data Modeler pricing and cost advice

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

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

"The solution is cheaper than its competitors."

"The product has a moderate pricing."

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

"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."
