Basic architecture of the SAP HANA engine

SAP HANA has different engines to process different views. It has the following engines:

It is the SQL optimizer, which sees the models and queries and decides which engine to call.

Any analytic view or attribute view with a calculate attribute will be processed as a calculation view. This should to be taken into consideration during modeling, because it can have a measurable impact on the performance of the data model. Different engines cooperate among themselves as well.

The following figure shows the SAP HANA engines processing different views:

Other than the preceding illustrated engines, we do have a planning engine as well in SAP HANA. The planning engine, allows financial planning applications to execute basic planning operations in the database layer. For example, one such basic operation is to create a new version of a dataset as a copy of an existing one while applying filters and transformations.
