We performed a comparison between SAP Data Hub and SAP PowerDesigner based on real PeerSpot user reviews.
Find out what your peers are saying about Informatica, Alation, SAP and others in Metadata Management."SAP is one of the most seamless ERPs that have integrated SAP archiving within Excel. I have not seen this with any other database."
"Its connection to on-premise products is the most valuable. We mostly use the on-premise connection, which is seamless. This is what we prefer in this solution over other solutions. We are using it the most for the orchestration where the data is coming from different categories. Its other features are very much similar to what they are giving us in open source. Their push-down approach is the most advantageous, where they push most of the processing on to the same data source. This means that they have a serverless kind of thing, and they don't process the data inside a product such as Data Hub. They process the data from where the data is coming out. If it is coming from HANA, to capture the data or process it for analytics, orchestration, or management, they go to the HANA database and give it out. They don't process it on Data Hub. This push-down approach increases the processing speed a little bit because the data is processed where it is sitting. That's the best part and an advantage. I have used another product where they used to capture the data first and then they used to process it and give it. In Data Hub, it is in reverse. They process it first and give it, and then they put their own manipulations. They lead in terms of business functions. No other solution has business functions already implemented to perform business analysis. They have a lot of prebuilt business functions for machine learning and orchestration, which we can use directly to get an analysis out from the existing data. Most of the data is sitting as enterprise data there. That's a major advantage that they have."
"The most valuable feature is the S/4HANA 1909 On-Premise"
"The most valuable feature is that it is a very fast reverse engineering process. It does a very expansive comparison."
"I like the connectivity or the lineage between the models and usability."
"SAP PowerDesigner is fairly stable."
"The most valuable features of SAP PowerDesigner are the creation the flow charts and folders. It is a powerful tool."
"It's a great tool for documentation."
"This solution has good tools for big data, where you can manage large and complex 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."
"It offers a lot of features in one solution. You would have to get multiple other products to bundle together all of the capabilities that you get in just this product."
"The company has everything offshore."
"Nowadays there are some inconsistencies in data bases, however, they upgrade and release the versions to market."
"In 2018, connecting it to outside sources, such as IoT products or IoT-enabled big data Hadoop, was a little complex. It was not smooth at the beginning. It was unstable. It took a lot of time for the initial data load. Sometimes, the connection broke, and we had to restart the process, which was a major issue, but they might have improved it now. It is very smooth with SAP HANA on-premise system, SAP Cloud Platform, and SAP Analytics Cloud. It could be because these are their own products, and they know how to integrate them. With Hadoop, they might have used open-source technologies, and that's why it was breaking at that time. They are providing less embedded integration because they want us to use their other products. For example, they don't want to go and remove SAP Analytics Cloud and put everything in Data Hub. They want us to use SAP Analytics Cloud somewhere else and not inside the Data Hub. On the integration part, it lacks real-time analytics, and it is slow. They should embed the SAP Analytics Cloud inside Data Hub or support some kind of analysis. They do provide some analysis, but it is not extensive. They are moreover open source. So, we need a lot of developers or data scientists to go in and implement Python algorithms. It would be better if they can provide their own existing algorithms and give some connections and drop-down menus to go and just configure those. It will make things really quick by increasing the embedded integrations. It will also improve the process efficiency and processing power. Its performance needs improvement. It is a little slow. It is not the best in the market, and there are other products that are much better than this. In terms of technology and performance, it is a little slow as compared to Microsoft and other data orchestration products. I haven't used other products, but I have read about those products, their settings, and the milliseconds that they do. In Azure Purview, they say that they can copy, manage, or transform the data within milliseconds. They say that they can transform 100 gigabytes of data within three to five seconds, which is something SAP cannot do. It generally takes a lot of time to process that much amount of data. However, I have never tested out Azure."
"You have the possibility to complete a connection for abbreviations if you are creating columns or names of the tables. In the Citrix environment, this has been lagging to the point where the PowerDesigner was not usable."
"SAP PowerDesigner could improve by making the repository easier to understand. It is difficult to understand how the repository works because when I used logical models as part of the team, we wanted to use them together and update the older versions of the data model version but it was confusing. The repository needs to be explained."
"Technical support needs improvement."
"The focus is more on mainstream development environments, and I see a lack of focus on the open source world. I think SAP PowerDesigner probably interfaces better with SQL Server and Db2 but not with open source databases like PostgreSQL and MySQL."
"Not very intuitive or user-friendly."
"There should be a better usage of current hardware including multicore CPUs, higher resolutions, and multiple displays."
"I've tried to use Power Designer to bring in images, which didn't work very well at all."
"It would be helpful if there were glossary, catalog and governance tools. It would help make it a true end-to-end product."
