"The most valuable feature is the S/4HANA 1909 On-Premise"
"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."
"It's a stable system. It never crashes."
"I like the connectivity or the lineage between the models and usability."
"The most valuable feature is the way you can extend it and customize it. With most modeling tools, you fit your modeling process to fit the tool. In PowerDesigner, you can make the tool fit the way you want to work."
"The physical database model is definitely the most valuable feature because it describes normalization exactly the way you understand the data, and it deploys it perfectly with open source systems."
"It has helped me to develop the as-is state, design its to-be state, and track the capital investment according to gap analysis."
"The most valuable feature is that it is a very fast reverse engineering process. It does a very expansive comparison."
"The most valuable features of SAP PowerDesigner are the creation the flow charts and folders. It is a powerful tool."
"The initial setup was very easy."
"Nowadays there are some inconsistencies in data bases, however, they upgrade and release the versions to market."
"The company has everything offshore."
"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."
"SAP PowerDesigner can improve the ease of use. It is not the best tool on the market because it is tough to navigate and use. A beginner would not be able to use it well, it requires some experience. If the solution was more user-friendly it would be able to be used by more audiences. I do not think many people are aware of this solution and they should use it."
"This product does not have a good BPMN Modeler."
"In terms of improvement, the pricing is a bit high."
"Technical support needs improvement."
"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."
"The data governance should be improved, like ER/Studio."
"There are many areas of this solution that needs to be changed."
"The solution is very, very expensive. It would be ideal if it was a more affordable product."
