We performed a comparison between erwin Data Modeler by Quest and SAP PowerDesigner based on real PeerSpot user reviews.
Find out in this report how the two Enterprise Architecture Management solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."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."
"It's a safeguard for me because I'm always concerned that somebody is free handing it and will forget a key coming from the parent. The migrating keys are a great feature. Identifying relationships, non-identifying relationships, and being visually right there to understand the differences are great features. erwin is key to being able to visually understand whatever the customer is requesting. They'll give you words on a paper, but once they can actually view it as a picture, it really comes to life. The data comes to life to where they understand exactly what they're asking for."
"We can create mappings in erwin and possibly data dictionaries."
"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."
"It allows us to create logical data models. We can represent a database model in business terms, which is very useful for us."
"Drag-and-drop data modeling and reverse engineering out of databases are the most valuable features of erwin Data Modeler by Quest."
"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."
"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."
"It can automate many routine tasks and save human resources to focus on real problems."
"The initial setup was very easy."
"I've used the reverse engineering feature a lot. I can take a look at the structure of the database and what relationships it has."
"It allows us to have proper documentation in terms of the databases."
"Very good repository features."
"I like the property sheet capability and the user-defined attributes that you can set up."
"In PowerDesigner, I primarily use BPM and modeling standards. I find it beneficial for process analysis, although I use data modeling to a lesser extent."
"In terms of operational efficiency and cause savings or return on investment, I can say that with SAP PowerDesigner, our company saves a lot of time."
"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."
"erwin is not as robust as a data warehousing project I've been on in the past."
"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."
"I would like the solution to be more user-friendly to deploy."
"There is a lack of local support in the China region."
"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 see the ability to support more NoSQL platforms more quickly. In addition, enhancing the graphics to render more quickly would be beneficial for any user."
"The solution's reporting side needs to be improved."
"The data governance should be improved, like ER/Studio."
"There are many areas of this solution that needs to be changed."
"It would be helpful if there were glossary, catalog and governance tools. It would help make it a true end-to-end product."
"I've tried to use Power Designer to bring in images, which didn't work very well at all."
"In terms of improvement, the pricing is a bit high."
"The tool lags in the area of customer service."
"Technical support needs improvement."
"Checking-in models to the repository, especially when working remotely, is a slow process than can sometimes have problems with models being corrupted."

15 years ago was the one time I chose to use PowerDesigner over Erwin Data Modeler was for a project where we have hundreds of pl/sql ETL scripts that needed to be run in a specific order for specific tables. PowerDesigner had the ability to store the pl/sql within the data model and prioritize/order the script run sequence. This meant that we could count on PowerDesigner to automatically generate the ddl and pl/sql code in the correct run order, rather than manually maintaining a spreadsheet with the script order and running each script manually, a VERY labor intensive process. I don't know if PowerDesigner still has that capability.
With all of the ways we have to program and perform ETL, Erwin Data Modeler has been my tool of choice for any other project throughout the years. Protecting intellectual property and transparently sharing data model information with other modelers by saving the the models in a centralized location (i.e. Model Mart) is important for any company. Making the data model diagrams transparently accessible via Web Portal is another important step in ensuring both technical and business users understand the structure and relationships of the data contains within a data store. Lastly, making the data model metadata available via the Erwin Data Intelligence Suite enables both technical and business users to completely understand everything about the data and data store: Business Glossary, Reference Data, Governance, Data Quality, Data Mapping, and especially automating data lineage and impact analysis.
