GM
IT/Business Architect at a financial services firm with 51-200 employees
Lots of valuable features, especially the metamodel customization
In terms of what could be improved, we did not take the whole package with all the modules, and I think that the integration with other platforms like Office could be better. The reverse engineering of the database is already there, but in the next release I would like to see some pilot supplied with the solution in order to address any database.

Data modeling tool improves data management and decision-making efficiency
The lineage analysis helps my organization understand data dependencies at an enterprise level. As a SAP PowerDesigner developer, I monitor data across the organization, creating data models that reflect not just one data warehouse but comprehensive organizational information. If you have a small company, lineage helps track employee data across different areas such as finance and HR. Data governance prevents duplicate records, so when tracking employee details, SAP PowerDesigner highlights where data exists in various areas, helping ensure we only use the appropriate sources. This functionality allows us to assess the impact of data deletions effectively. I utilize the reverse engineering capabilities in SAP PowerDesigner. Reverse engineering is helpful, especially since I have colleagues new to SAP PowerDesigner. They often do not know which columns are available where. In SAP PowerDesigner, we can reverse engineer existing data from its source and identify errors in production. For instance, by using Ali's example, if an error arises, I can trace it back to the table and environment it originated from using the reverse engineering feature. The best features of SAP PowerDesigner, from my perspective, are its ability to keep the connectivity between the source database and the new system, data redundancy and availability, and impact analysis. The first feature acts as a bridge between systems. The second allows us to see what data is already available and what new data can be brought in. The third, impact analysis, helps determine how many tables will be affected if a specific table is deleted. This critical point allows us to capture how much data will be lost if any table is removed. Currently, these features shape my daily work. SAP PowerDesigner primarily benefits business management units by offering three types of data modeling structures: conceptual, logical, and physical models. The conceptual model communicates high-level insights to top executives, while logical and physical models address complex queries faced by developers in analytics. SAP PowerDesigner enhances the clarity of our data management significantly, as around 80% of data can be searched quickly and maintained in our SAP systems. The tool enables mapping from end to end, making my work faster and more efficient than using other ER data modeling solutions. The interface allows easy creation of data models and searching for existing data, ensuring I can complete my tasks significantly quicker. The importance of SAP PowerDesigner's collaboration capabilities lies in fostering a unified data management approach. It acts as a unified tool, preventing the duplication of existing data in analytical processes, thus saving both effort and storage costs, which is essential for effective data management. We utilize collaboration capabilities in SAP PowerDesigner with various source systems such as PG admin, Postgres, Oracle, and Snowflake. Recently, we have added Snowflake for cloud data modeling and POC work, streamlining the collaboration process across different systems.

Quotes from Members

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

Pros

"There are a lot of features I find valuable, but I think that the metamodel customization is one of the best features that the solution offers."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"We have seen ROI with this solution over the years that we have used it."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"The System Architect Product has greatly assisted the corporate strategic planning process in two areas: the simulation of scenarios for Enterprise Transformation Projects and providing a global view of Enterprise Capabilities and Functional Gaps."
"The solution is pretty stable."
"SAP PowerDesigner enhances the clarity of our data management significantly, as around 80% of data can be searched quickly and maintained in our SAP systems."
"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."
"Has a specific template that's very helpful for importing metadata."
"One of the key reasons for choosing this solution above others is because of the repository features which we're able to consolidate and work on a single repository where we store all our models in one location."
"SAP PowerDesigner is an excellent tool that does what I need it to do. What I like most about it is that it's stable, fast, and easy to understand."
"Provides the flexibility to create logical and conceptual data models."
"I mostly work on the conceptual and logical side of things, and I enjoy how easy it is to use."
"The most valuable features of SAP PowerDesigner are the creation the flow charts and folders. It is a powerful tool."
 

Cons

"There needs to be more information at the outset about how to use the solution and how to deploy it. The deployment process needs improvement."
"The reverse engineering of the database is already there, but in the next release I would like to see some pilot supplied with the solution in order to address any database."
"It was sold separately and it is not very easy for somebody who wants to use the solution for modeling to think that you have to select specific modules in order to use the product."
"This solution can be more user-friendly and easier to use, with better dashboards."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"Some aspects of the user interface lack a common navigational or functional framework."
"We are not happy with this product and are not planning to continue with it."
"The solution needs to better integrate with other products, like Microsoft."
"Regarding improvements, I suggest enhancing the connection between objects in process and data models. It's crucial to define the structure of objects, especially when dealing with standard frameworks like VMM. There should be better visualization of arrows between BPM and data modeling objects, specifying their structure and impact. For future versions, a feature similar to Bizagi, allowing users to see forms or SQL representations of objects, would be valuable for demonstrating and presenting project details to stakeholders."
"UI could be improved by enabling simpler navigation."
"There are many areas of this solution that needs to be changed."
"Technical support could be better and more human."
"The solution is very, very expensive. It would be ideal if it was a more affordable product."
"Better support for integration with open-source technologies is needed. For example, I try to use open-source databases such as Postgres and MySQL instead of Microsoft, DB2, or Oracle, however, I think it's lacking in capability from the tool to the database."
"The meta-model (a.k.a. how objects are supposed to be connected to each other) seems to be proprietary."
"Reverse-engineering of late JDK and .NET. Use third party parsers and enhance Object-Oriented metamodel to cater for newer language features."
 

Pricing and Cost Advice

Information not available
"The price of the solution is too expensive. When we asked for certain licenses in different countries it was unattainable."
"I would like SAP to prove free licenses to professionals that are using the solution. The free version is limited."
"When you purchase the license for SAP PowerDesigner, you have to buy one year of support. The tool is worth the money."
"Regarding costs, SAP PowerDesigner is pricey, as I've heard from my team manager, which is why the company has been thinking of bringing another solution on board."
"I bought the software outright and do not pay a licensing fee."
"The price of the solution is low."
"PowerDesigner is not the cheapest solution on the market, so make sure that you are using it to its full potential."
"The ROI has been 43%."
