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 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 main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"We have seen ROI with this solution over the years that we have used it."
"The solution is pretty stable."
"In summary, this product gives you all of the features that a modeler would require to produce both logical and physical data models."
"It's a stable system. It never crashes."
"By using SAP PowerDesigner, we are able to create a product that is always up to date, so the model always represents the implementation."
"It is a very stable solution, which is one of the advantages of using PowerDesigner, especially in big databases."
"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."
"The most valuable features of SAP PowerDesigner are the creation the flow charts and folders. It is a powerful tool."
"The feature I found valuable in SAP PowerDesigner is extraction. I also like that my company hasn't faced any issues because of the clear documentation about SAP PowerDesigner."
"The main valuable features are the logical and physical data modeling capabilities, and our main purpose is to keep the data model in a repository and then be able to generate DDL files for Oracle."
 

Cons

"We are not happy with this product and are not planning to continue with it."
"Some aspects of the user interface lack a common navigational or functional framework."
"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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"This solution can be more user-friendly and easier to use, with better dashboards."
"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."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"They didn't spend any time on the issue because according to them, 16.5 is not supported."
"However, the pricing for small consultancies needs to be improved. The competing vendors often have special offers that make the tool more affordable, which is vital for data management consultancies that have to buy the tools that their clients use."
"Checking-in models to the repository, especially when working remotely, is a slow process than can sometimes have problems with models being corrupted."
"Although the presentation for viewing the models is good, I think it could be better."
"I would like SAP to prove free licenses to professionals that are using the solution. The free version is limited."
"Synchronization is vital since I experience multiple problems, such as mismatched models and manual DDL handling."
"One issue is the cost, as it is a high-priced tool coming from SAP."
"I have found the solution not easy to use. When publishing you have to download the HTML, make adjustments against the updated HTML, convert it to HTML, then finally paste the HTML. There is not an on-the-fly function available to bypass the step-by-step converting process that other solutions have."
 

Pricing and Cost Advice

Information not available
"I bought the software outright and do not pay a licensing fee."

"SAP PowerDesigner is cheaper than eriwin."
"The price of the solution is too expensive. When we asked for certain licenses in different countries it was unattainable."
"When you purchase the license for SAP PowerDesigner, you have to buy one year of support. The tool is worth the money."
"PowerDesigner is not the cheapest solution on the market, so make sure that you are using it to its full potential."
