Is your business report designed well enough for a perfect analysis


 We are all well versed in the types of CDS Views used in SAP HANA. However, they are still evolving and adapting to the latest technology provided by HANA. This article focuses on an analytical angle of the CDS Views.


Before understanding the concept of analytics, it is very important to understand the concept of VDM.

What is VDM?

VDM or Virtual Data Model is a combination of semantically enriched CDS Views that logically combine database tables to create a meaningful data set. It is basically built to create a consumption model from any system or an environment.

There are three types of VDM used:

  1. BASIC - The basic CDS views or entities that extract data from the database tables and forms base of any reports or other CDS Views are classified as BASIC CDS Views.
  2. COMPOSITE - Views that are made by joining two or more than two Basic CDS Views are known as composite CDS Views. These views also serve aggregation level data.
  3. CONSUMPTION – The views that are exposed to the outer environment are known as consumption views. These are the topmost views which are a base of applying queries and creating metadata extensions with annotations. These views are also exposed as ODATA Services.
