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

"I have worked with erwin Data Modeler for quite some time and familiarity is its most valuable feature."
"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."
"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 most valuable features are being able to visualize the data in the diagrams and transform those diagrams into physical database deployments. These features help, specifically, to integrate the data. When the source data is accumulated and modeled, the target model is in erwin and it helps resolve the data integration patterns that are required to map the data to accommodate a model."
"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 is a scalable solution...The technical support team is fine."
"It reduces monthly savings by hundreds of thousands of dollars. Think about a company like Costco and all of the points of sale systems in Costco, all of the systems, the applications, but if all the applications in Costco all had their own data model, trying to integrate those, upgrade them and manage their different versions of the same model throughout the store, is an absolute nightmare. It's phenomenally expensive. This helps reduce that cost significantly. I'm talking on the orders of hundreds of thousands of dollars."
"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."
"iServer has valuable features for workflow and document management."
"iServer is a solution that helps catalog enterprise architect solutions and catalog information."
"We like the governance."
"The initial setup is easy."
"Good and effective reporting features, which help in decision making."
"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."
"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

"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."
"I find the UI very clunky and very difficult to use. If I add columns to a table the whole workflow could be so much easier. I get frustrated using it. I've tried other tools. I've tried to get off of erwin a few times. I always come back to it because every tool has its own set of problems, and it seems like if I have to pick my poison, I stay with erwin. But so many things that are clunky with it."
"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 am not so happy with its speed. Sometimes, it can have problems with connections."
"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."
"As someone who has used it for a long time, I have seen stability vary from version to version."
"The erwin Data Modeler is quite complex to use."
"The navigation is a little bit of a challenge. It's painful. For example, if you've got a view open and you want to try to move from side to side, the standard today is being able to drag and drop left and right. You can't really do that in the model. Moving around the model is painful because it doesn't follow the Windows model today."
"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."
"There are other solutions out there that have a better user interface."
"Enhancing integration options with ERP or ITSM-related solutions for triggering automated requests for process definitions, changes, and tracking them in the iServer."
"We could allocate permissions to use only specific components to the users rather than the entire instance."
"The modelling needs improvement, specifically forecasting capabilities and scenarios."
"There could be features for process mining, process simulation, and analytics."
"The migration tool needs to be included in the main package, and not as a separate license."
"I haven't used this solution long enough to know what areas could be improved."
 

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."
"The pricing of the solution is cheap. I rate the pricing a five out of ten."
"There is either a one-year or three-year license. It is not a pay-as-you-go license like a SaaS solution. It’s more of a traditional licensing. They are a little bit on the pricier side."
"There are no costs in addition to the standard licensing fees."
"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."
"Likewise, the solution is a little pricey."
"The tool is expensive."
"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."
"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 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."
"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."
