2. 4 Required Qualifications for Developers How should ABAP developers deal with the impact of SAP HANA on application development? It’s certainly not enough to simply understand the impacts described. To be able to optimize existing applications and develop new applications or application types based on ABAP and SAP HANA, developers need to gain expertise. And you should make sure to acquire this knowledge at an early stage. From our point of view, you should gain detailed knowledge of Open SQL (if you are not already highly skilled in this language), but should also familiarize yourself with technologies of the SQL standard and the SAP HANA database that go beyond Open SQL.
Range partitioning supports partition pruning. These partitioning types can be combined in a two-step approach. For instance, you could use hash partitioning in the first step and then, in a second step, use range partitioning within this hash partitioning. 3 Architecture of the In-Memory Database This section introduces important aspects of the SAP HANA database architecture. 8 shows the main components of the architecture. 8 Architecture of the SAP HANA Database Server and engine components The following section provides a detailed description of all of these architecture components, which can be subdivided into two component types: EE Server Server components are processes and services that are run on the operating system.
EE Integrated scenarios In an integrated scenario, existing applications are migrated to SAP HANA and the traditional database is replaced with SAP HANA. SAP HANA becomes the primary database. 9 shows two typical side-by-side scenarios: accelerators and SAP HANA applications. Accelerator scenarios In an accelerator scenario, the data from the traditional database is replicated to an SAP HANA database. Certain reading database accesses within existing applications are redirected to SAP HANA. This can be done using different procedures.
