SAP HANA is a technology platform for the new generation of SAP. This is a RDBMS fulfilling the famous ACID requirements (automaticity, consistency, isolation, and durability) and a development platform and application server within the same environments. The database management server is the index server component and most components of the development platform reside in the XS server. SQL is the native language of the index server and applications of the XS server are mostly exposed via HTML5 user interface. SAP HANA is divided into three parts: 1. Instance, 2. System and 3. Host Instance is used to refer to the collection of processes and programs that are created when we installed the software. The instance consists mainly of the start processes, the core database processes and some of the SAP HANA auxiliary processes. This is identified by SID and instance no.
