Their main features are as follows:
- CDS views support basic software architecture requirements because they can be stacked and designed in layers.
- CDS views offer a tool-supported declarative design of database operations without the need to learn Structured Query Language (SQL).
- CDS view syntax offers a rich set of Data Manipulation Language (DML) commands.
- CDS views can be annotated to indicate reusability. They offer different kinds of technically and semantically stable contracts.
- CDS views that are publicly available follow stable naming conventions for views and attributes.
- CDS views are used to model access to SAP business objects. Each business object represents one or many database tables, which form a strong business relationship (i.e., header item).
- CDS views offer an extension concept, so that you can easily extend business objects with your own fields.
- CDS views may directly interact with native SAP HANA functions.
- CDS views allow the direct execution of authorization checks when retrieving data from the database.
- CDS views support text-index-based search.
- CDS views natively support OData.
- CDS views can be directly accessed by ABAP programs and are visible in the ABAP DDIC.
