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 accuracy and speed of the solution in transforming complex designs into well-aligned data sources make the cost of the tool worth it."

"The best features of erwin Data Modeler include the forward engineering tool, which gives you the schema according to the data model that you generate."

"It allows us to create logical data models. We can represent a database model in business terms, which is very useful for us."

"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."

"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."

"The product allows us to reuse entities and attributes."

"It supports a wide variety of databases, including the latest ones. We have chosen to go for a cloud-based database, and it supports that, which is very useful."

"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."

More erwin Data Modeler pros

"I love how there are no milestone swimlanes."

"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."

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

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

"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 initial setup is easy."

"We like the governance."

More iServer pros

Cons

"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."

"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 improved reporting and, potentially, dashboards built on top of that."

"Sometimes when I want to open the attribute editor, it stops working and the whole application freezes."

"The erwin Data Modeler is quite complex to use."

"I still use Visio for conceptual modeling, and that's mainly because it is easier to change things, and you can relax some of the rules. DM's eventual target is a database, which means you actually have to dot all the Is and cross all the Ts, but in a conceptual model, you don't often know what you're working with. So, that's probably a constraint with erwin. They have made it a lot easier, and they've done a lot, but there is probably still room for improvement in terms of the ease of presentation back to the business. I'm comparing it with something like Visio where you can change colors on a box, change the text color and that sort of stuff, and change the lines. Such things are a whole lot easier in Visio, but once you get a theme organized in erwin, you can apply that theme to all of the objects. So, it becomes easier, but you do have to set up that theme."

"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."

"We are planning to move, in 2021, into their server version, where multiple data modelers can work at the same time and share their models. It has become a pain point to merge the models from individual desktops and get them into a single data model, when multiple data modelers are working on a particular project. It becomes a nightmare for the senior data modeler to bring them together, especially when it comes to recreating them when you want to merge them."

More erwin Data Modeler cons

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

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

"Setting up the Portal was very complex. We required a lot of support from the vendor."

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

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

"We could allocate permissions to use only specific components to the users rather than the entire instance."

"Cannot see which activities are control activities."

"It's a very simple tool, which makes me concerned with the performance."

Pricing and Cost Advice

"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."

"This company had bought the license for three years, and it's not an individual license. While you can buy a license for each individual, that would be very expensive. There is something called concurrent licenses where you can purchase licenses in bulk and 15 to 20 people can access the license and model. Concurrent licenses are scalable to the number of users and are proportional to the cost."

"The pricing of the solution is cheap. I rate the pricing a five out of ten."

"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."

"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 tool is expensive."

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

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

More erwin Data Modeler pricing and cost advice

"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."

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

"The solution is cheaper than 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."
