CDView Data Model Sample For ABAP Application
CDView is a picture viewer and browser that lets you browse CD-ROMs and DVDs and even search for images. CDView is especially helpful for personal albums, catalogs, presentations, and archives. It also supports a variety of special CD-ROM and DVD features like full screen and slide show. You can even rename, edit, and delete pictures in the program.
The data model in CDS Views is defined by defining a view entity, and then accessing the underlying data source. A view entity is a subset of a CDS table and provides improved features. The sample for this view entity is very clean and follows the same syntax as other CDS-based views.
A CDS view entity replaces the classic DDIC-based view in ABAP. The CDS view entity has several technical improvements and is recommended over the CDS DDIC-based view. In ABAP 7.40, SP05, a CDS view entity is declared by using DEFINE VIEW. The DDIC view is named using a DDIC / ABAP dictionary view name, which specifies the view name.
A CDS view enables the application to work with the data in a more streamlined manner. It can support multiple databases and ABAP/ABAP applications. It also allows the developer to build models directly in the database. The ABAP version of a CDS view uses an ABAP model, while the HANA version supports native SAP HANA applications. Both versions of CDS view have their own release cycles and functionalities.
