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

"I compare erwin Data Modeler with other solutions such as ER/Studio and believe it stands out as an enterprise-grade data modeling tool capable of serving different industries, such as finance, healthcare, and telecom."
"We use the Forward and Reverse Engineering tools to help us speed things up and create things that would have to be done otherwise by hand. E.g., getting a database into a data model format or vice versa."
"We find that its ability to generate database code from a model for a wide array of data sources cuts development time. The ability to create one model in your design phase and then have it generate DDL code for Oracle or Teradata, or whichever environment you need is really nice. It's not only nice but it also saves man-hours of time. You would have to take your design and just type in manually. It has to take days off out of the work."
"When you're getting down to the database level, where you're building a design and you're creating DDL out of it, or you're going in the other direction where you're reaching into system catalogs and bringing things back, that starts to really require specialization. Visio isn't going to reverse-engineer that for you. Those features in erwin are valuable."
"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."
"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."
"The solution’s code generation ensures accurate engineering of data sources, as there is no development time. Code doesn't even have to be reviewed. We have been using this solution for so long and all the code which has been generated is accurate with the requirements. Once we generate the DDLs out of the erwin tools, the development team does a quick review of the script line by line. They will just be running the script on the database and looking into other requirements, such as the index. So, there is less effort from development side to create tables or build a database."
"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."
"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."
"iServer has valuable features for workflow and document management."
"The product has a valuable customized model."
"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."
"This flexibility is the most helpful part in the standard version."
"Good and effective reporting features, which help in decision making."
"Tech support is very responsive. They solved issues within a prompt response time."
"iServer is a very flexible platform for defining your own enterprise architecture model."
 

Cons

"This is a very complex product."
"It does not have a cloud application."
"I am not so happy with its speed. Sometimes, it can have problems with connections."
"The erwin ETL functionality has room for improvement when it comes to mapping databases with a classic entity-relationship model to a data warehouse model."
"It is not a very stable solution. I rate the stability five out of ten."
"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."
"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."
"It has a very steep learning curve, limited support for NoSQL or streaming systems, and potentially a high licensing cost."
"I haven't used this solution long enough to know what areas could be improved."
"iServer should invest in enhancing the capabilities of the embedded drawing tool, draw.io."
"The product is more expensive than Spark."
"More visualization techniques and ways to report the data might be helpful."
"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."
"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."
"It runs relatively slowly."
 

Pricing and Cost Advice

"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."
"Though the solution is not cheap, it's worth the money."
"The price of erwin Data Modeler is very expensive, in particular for this part of the world."
"There are two license options and the pricing is reasonable."
"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."
"erwin is expensive compared to other solutions. We are paying almost $6,000 per seat a month."
"The primary reasons that erwin was selected were that it was much more affordable for us [than Embarcadero] and it was easily maintainable."
"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."
"The solution is cheaper than its competitors."
"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."
