Data Platform & Data Management

The good performance of a HANA database stems from the systematic orientation to an in-memory database, as well as using modern compression and Columnstore algorithms. This means that the database has to read comparatively less data when calculating aggregations for large quantities of data and can also perform this task exceptionally quickly even in the central memory.

However, one of these benefits may very quickly be rendered moot if the design of the data model is below par. As such, major benefits in terms of runtime and agility may become null and void for both the HANA database, as well as the users.

In order to ensure performant reporting based on SAP BW, it is necessary to avoid redundant requests. An important element in this context is the optimized master data request. This can be implemented particularly easily and effectively for hierarchy objects (especially menu hierarchies).

When working with arcplan, there are different methods to generate a list without duplicates from a list of data with double entries. In many cases, a database consultation grouped accordingly may perform this task. Time and again, however, there are cases in which it is necessary to remove the duplicates with the assistance of arcplan functions.

When a BW system uses an SAP HANA database, it is possible to use what are called „Mixed Scenarios“. In these scenarios you can use SAP HANA tools to combine data modeled in both the BW system and in SAP HANA.
