Component: BC-ABA
Component Name: ABAP Runtime Environment
Description: An infrastructure which implements the general CDS concept for the AS ABAP. It provides a platform-independent CDS DDL which allows you to define CDS views and CDS table functions in the ABAP Dictionary that implement a semantic data model. There is also a platform-independent CDS DCL which allows you to develop CSD roles for CDS access control. In addition, you can edit specific classical objects of the ABAP Dictionary in the ABAP Development Tools ADT by using a syntax similar to the CDS DDL of the ABAP CDS.
Key Concepts: ABAP Core Data Services (CDS) is a data modeling language used to define and consume semantically rich data models in SAP systems. It is part of the ABAP Runtime Environment (BC-ABA) and provides a unified data access layer for both ABAP and non-ABAP applications. CDS allows developers to define data models that are independent of the underlying database technology, making it easier to access and manipulate data from multiple sources. How to use it: CDS can be used to define data models in the form of views, which can be used to access and manipulate data from multiple sources. The views can be used in ABAP programs, as well as in other applications such as SAP HANA or SAP BusinessObjects. CDS also provides a set of tools for creating, managing, and analyzing data models. Tips & Tricks: When creating a CDS view, it is important to consider the performance implications of the view. For example, if the view contains multiple joins, it may be more efficient to create separate views for each join instead of one large view. Additionally, CDS views can be optimized by using annotations to specify which fields should be indexed or which fields should be excluded from the view.
