Newest Development Features: where ABAP meets SAP HANA
“Newest development features for SAP ABAP on HANA basically includes database independent programming with open SQL, Unified data modelling & simplified control of stored procedures with ABAP-managed database procedures.”
- (1888PressRelease) April 01, 2018 - ABAP establishes the framework for countless SAP applications, with an expansive scope of highlights and usefulness for making effective business solution. SAP HANA furnishes the chance to improve with new and modern innovations. With support package stack (SPS) 05 for SAP NetWeaver 7.4, SAP has carried ABAP and SAP HANA together with highlights that empower developer to use the best of the two universes, in new custom improvement ventures, as well as in their current applications. Conveyed as a universally accessible administration discharge in December 2013, SPS 05 offers numerous new artifacts that ABAP developer can use to push down code to SAP HANA and convey advancement to their applications at different levels of abstraction.
Database-Independent Programming with Open SQL
In ABAP-based conditions, Open SQL has given the best possible level of abstraction for database processing for a long time, empowering ABAP projects to perform tasks on any SAP-supported database. The fundamental favorable circumstances of Open SQL are its database-platform-independence; its coordination into the ABAP language and runtime condition by methods for inner tables; and solid help of SAP NetWeaver Application Server (SAP NetWeaver AS) ABAP with table buffering, SQL statement storing, and cursor caching. Numerous tools are available, such as the ABAP source editor and the SQL trace tool (transaction ST05), to facilitate Open SQL programming during application design mode and to monitor and trace SQL execution during execution mode. Open SQL gives an ideal intends to ABAP developer to extract from the qualities of the fundamental database — In fact, designers are regularly aware that which database stage is really utilized underneath.
Numerous traditional ABAP programmers utilize a programming style that focuses on the application server. In particular, they regularly utilize extensive settled SELECT loops that are frequently very characteristic for handling vast informational indexes, yet basically duplicate every single important datum to the application server, where the information is overseen in ABAP inside tables. At the point when the Processing is done and changes are made, the inner tables are written back to the database. There are numerous current custom reports in client scenes that utilization a comparative execution scheme, both in dialog and batch processing.
Unified Data Modeling and Definition with Core Data Services
CDS gives a scope of preferences to ABAP developer, including:
1. Semantically rich data models. CDS expands on the well-known entity relationship model and is declarative in nature, near applied reasoning.
2. Compatibility across any database stage. CDS is produced into overseen Open SQL views and is locally incorporated into the SAP HANA layer.
3. Effectiveness. CDS offers an assortment of profoundly effective built-in capacities —, for example, SQL operators, aggregations, and expressions — for creating views.
4. Support for annotation. The CDS syntax supports domain specific annotation that can be effortlessly assessed by different segments, for example, the UI, examination, and OData services.
5. Support for conceptual associations. CDS helps you to characterize affiliations that fill in as connections between various perspectives.
6. Extensibility. Clients can expand SAP-characterized CDS views with fields that can be consequently added to the CDS views.
Simplified Control with ABAP-Managed Database Procedures
Database methods are important tool for ABAP developer. They enable designers to compose their projects all the more clearly by consolidating logic in a central location, empowering it to be reused over different applications, and they additionally give the capacity to perform integrity checks and grant privileges. With SAP HANA, database strategies push down intensive logic to the database. At first, these strategies were made and overseen in the SAP HANA studio and devoured by the ABAP layer. SAP NetWeaver 7.4 SPS 05 presents another approach, known as ABAP-oversaw database systems (AMDPs).
