To get to the bottom of the many aspects of CDS View SAP, let us first understand what CDS is about. CDS represents Core Data Services, an intuitive, user-friendly, and robust programming language that was developed and introduced by SAP. You do not have to go through the application server to define and consume models on the database with CDS View SAP. Instead, CDS View is an optimized platform that creates data models with OData services that can be moved outside the applications. This aspect is one of the unique features of CDS View SAP.
While traditional databases are based on application servers, data models on CDS SAP operate on database servers. When organizations need to monitor real-time database performance, the in-memory database of SAP HANA can be leveraged through CDS View SAP, a data modeling framework.
This requirement can be met by optimizing operations at the database level that leads to reduced application execution time and quick retrieval of databases. Further, users can access data models presented by application servers through SAP CDS through UI and CDSView SAP.
The Functions of SAP CDS Views
One of the most critical requirements in today’s business environment is to undertake real-time data reporting and analytics on transactional data. SAP HANA has fulfilled this requirement as large queries (analytics) on S/4 HANA can be optimally performed without needing a separate data warehouse or facing any lack or degradation in performance. Additionally, CDS View SAP can directly create VDMs (Virtual Data Models) in ERP that can be used as high-performing front-end tools.
It is now possible to define a view in a CDS View SAP document with SAP HANA XS (SAP HANA Extended Application Services). It can be stored as design-time files in the repository and read by applications developed specifically for this purpose. These files located in the data repository have definitions and can be moved to other SAP HANA systems like a delivery unit.
It is not necessary to determine the underlying structures/tables to use CDS View SAP for real-time data analytics on live transactional data. This is because of the several advanced features built into the SAP S/4 HANA Embedded Analytics. These views are combined with both modified new views or used directly to create new views.
Once a CDS document is activated, a catalog object for each object as given in the document is correspondingly generated. The type ofobject determines the exact location of the catalog. For instance, going by the definition of CDS View SAP, the catalog object corresponding to SAP HANA XS classic is generated in the location <SID> Catalog <MYSCHEMA> Views.
The main benefit of the CDS View SAP is that it is a code-to-data technology in ABAP with all computing and calculations done directly on the database layer instead of the application server. Moreover, since CDS View SAP operates independently of the database, it can be operated on any database platform supported by SAP.
