What is virtual data model in SAP CA-GTF - General Application Functions?

SAP Term: virtual data model

• Component: CA-GTF

• Component Name: General Application Functions

• Description: A structured representation of CDS views in SAP S/4HANA and SAP S/4HANA Cloud. The virtual data model forms the basis for data access in SAP S/4HANA in, for example, analytical consumption or APIs. The CDS views thatmake up the virtual data model follow consistent modelling and naming rules. They expose business data - stored in abstract tables - in a way that is based on business semantics and therefore easier to consume.

• Key Concepts: 
  A virtual data model (VDM) is a component of the SAP General Application Functions (CA-GTF) that allows users to access and manipulate data from multiple sources in a single view. It provides a unified view of the data, allowing users to quickly and easily access the information they need. The VDM also provides a layer of abstraction between the user and the underlying data sources, allowing for more efficient data access and manipulation.
  
  How to use it: 
  The VDM can be used to access and manipulate data from multiple sources in a single view. To do this, users must first define the data sources they want to access. This can be done by creating a virtual table that contains the necessary information from each source. Once the virtual table is created, users can then query the data using SQL commands. The VDM also provides a layer of abstraction between the user and the underlying data sources, allowing for more efficient data access and manipulation.
  
  Tips & Tricks: 
  When using the VDM, it is important to ensure that all of the necessary information is included in the virtual table. This will ensure that all of the necessary data is available for querying. Additionally, it is important to ensure that all of the necessary security measures are in place when accessing and manipulating data from multiple sources.
  
  Related Information: 
  The VDM is part of SAP's General Application Functions (CA-GTF). Other components of CA-GTF include Business Intelligence (BI), Enterprise Resource Planning (ERP), and Supply Chain Management (SCM). Additionally, SAP offers a range of other tools and services that can be used to access and manipulate data from multiple sources.
