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

"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."

"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."

"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."

"It has centralized storage so that a data model can be shared by different teams."

"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."

"The modeling portion of the tool is the most valuable. There are some notes, naming standards, and other functions that we use as well. There's a whole boatload of functionality in this thing and we use maybe 10% of it. It seems to be pretty common that not all the functionality is fully utilized. But it's just got gobs and gobs of stuff that you can implement if you so choose to."

"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."

"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."

More erwin Data Modeler pros

"The most valuable feature is its reporting capability. It offers various packages for different types of reports, such as business and project management reporting packs."

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

"This flexibility is the most helpful part in the standard version."

"We like the governance."

"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."

"The solution has wide use within Microsoft products. The integration with Microsoft products, and, in particular, Microsoft Office, is great."

"iServer has valuable features for workflow and document management."

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

More iServer pros

Cons

"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."

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

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

"As someone who has used it for a long time, I have seen stability vary from version to version."

"There is a lack of local support in the China region."

"erwin generally fails to successfully reverse engineer our Oracle Databases into erwin data models. The way that they are engineered on our side, the syntax is correct from an Oracle perspective, but it seems to be very difficult for erwin to interpret. What I end up doing is using Oracle Data Modeler to reverse engineer into the Oracle data model, then forward engineer the DDL into an Oracle syntax, and importing that DDL into erwin in order to successfully bring in most of the information from our physical data models. That is a bit of a challenge."

"I would like the solution to be more user-friendly to deploy."

"I would like to see improved reporting and, potentially, dashboards built on top of that. Right now, it's a little manual. More automated reporting and dashboard views would help because currently you have to push things out to a spreadsheet, or to HTML, and there aren't many other options that I know of. I would like to be able to produce graphs and additional things right in the tool, instead of having to export the data somewhere else."

More erwin Data Modeler cons

"The migration tool needs to be included in the main package, and not as a separate license."

"Cannot see which activities are control activities."

"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."

"iServer should invest in enhancing the capabilities of the embedded drawing tool, draw.io."

"More visualization techniques and ways to report the data might be helpful."

"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."

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

"The product is more expensive than Spark."

More iServer cons

Pricing and Cost Advice

"Likewise, the solution is a little pricey."

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

"The price should be lower in order to be on the same level as its competitors."

"erwin is expensive compared to other solutions. We are paying almost $6,000 per seat a month."

"The solution is expensive."

"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 primary reasons that erwin was selected were that it was much more affordable for us [than Embarcadero] and it was easily maintainable."

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

More erwin Data Modeler pricing and cost advice

"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."

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

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

"The product has a moderate pricing."
