JorgeSanz - PeerSpot reviewer
Streamline data modeling and automate network changes for increased efficiency
The initial setup depends on the tool if you are using the data model environment. Stopping the server could be complex and require strong expertise. If you have everything set up and configured, Erwin is straightforward. You can deploy it in a few hours. In our case, it took a couple of months to address internal conditions, assign machines, and set up everything for the services. I rate the initial setup a six out of ten, where one is difficult and ten is easy.

Quotes from Members

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

Pros

"erwin has versioning so you can keep versions, over time, of those models and you can compare any version to any version. If you're looking at a specific database and you want to see what changed over time, that's really useful. You can go back to a different version or connect that to your change-control processes so you can see what was released when."
"The product lets us import different types of models from various databases."
"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."
"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 product allows us to reuse entities and attributes."
"They have a lot of features and the most up-to-date technology integration, which I haven't seen in other products."
"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."
"It has centralized storage so that a data model can be shared by different teams."
"It has helped having data lineage in the business cluster, which is used as control artifacts."
"The solution is easily modified to suit your needs."
"I have to think less with this solution. It's simple."
"There were lots of different requirements, and collaboration and review is one of the biggest things. There is also Office 360 integration, and there's flexibility to use it as a database as well."
"iServer is a very flexible platform for defining your own enterprise architecture model."
"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."
"The product has a valuable customized model."
 

Cons

"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."
"In terms of improvements, support could have been better in terms of installation, especially of workgroups. We struggled quite a bit to get it up and running. Collaboration could have been better from an installation perspective, but it is trivial as compared to what we use it for. Other than that, I don't have much feedback. It works pretty well, and the fact that we've been using it for more than a decade shows that it is quite solid."
"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."
"In terms of new features, it would be great to have a cloud base. We should be able to put it on the cloud for better collaboration and data models sharing."
"This is a very complex product."
"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."
"Although Quest Software has made tremendous strides in recent years, they need to evolve more in the big data arena; erwin Data Modeler could use a little more work when it comes to big database designs."
"The solution's reporting side needs to be improved."
"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."
"It definitely needs help to improve the visual aspect of the solution."
"We could allocate permissions to use only specific components to the users rather than the entire instance."
"It runs relatively slowly."
"There could be features for process mining, process simulation, and analytics."
"iServer should invest in enhancing the capabilities of the embedded drawing tool, draw.io."
"Enhancing integration options with ERP or ITSM-related solutions for triggering automated requests for process definitions, changes, and tracking them in the iServer."
"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

"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."
"The tool is expensive."
"It is not a very expensive solution. Only the licensing and maintenance fee needs to be paid."
"The price should be lower in order to be on the same level as its competitors."
"The pricing of the solution is cheap. I rate the pricing a five out of ten."
"Price-wise, erwin Data Modeler is okay. You can purchase a single license and it is not very expensive."
"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."
"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."
"The product has a moderate pricing."
"The price of iServer is reasonable compared to other solutions."
"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."
"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 solution is cheaper than its competitors."
