SITIST 2015 Dev - Abap on Hana
- 1. ABAP on HANA Tolga POLAT
- 2. What is HANA? An in-memory database is a database management system that primarily relies on main memory for computer data storage A column-oriented DBMS is a database management system (DBMS) that stores data tables as sections of columns of data rather than as rows of data.
- 3. ABAP in Eclipse ADT ( The ABAP Development Tools ) for SAP NetWeaver are SAP's state-of-the-art IDE for ABAP development on the open Eclipse platform. They are designed to significantly increase developers productivity by providing the ABAP developer the unique opportunity to perform development tasks in the comfortable ABAP environment while at the same time benefiting from the proven usability, speed and flexibility of the well-known Eclipse platform. Key Features Highly flexible, customizable Eclipse UI for ABAP development tools High-performance, failover-safe online development in several ABAP systems simultaneously Display and edit functionality for multiple ABAP objects in parallel Advanced and efficient source code editing including refactoring support Fast search and navigation capabilities Cross-system version management Ideal support of task-oriented and test-driven development Built-in extensibility of the IDE through the established Eclipse plug-in technology Powerful SDK for building and integrating custom ABAP development and testing tools (planned)
- 4. ABAP Development Database was a black box to ABAP Developer for many years. ABAP Developer was focusing on front-end application and dealing with data in front-end. ABAP Developer have SE11 ( ABAP Dictionary ) to create or change database table but actual work handled by SAP Database Interface.
- 5. ABAP Development with HANA SAP HANA brings new capabilities, but also enforces a new paradigm ‘code-2-data’ (aka code pushdown) where data-intensive processing (e.g. costly calculation on large datasets) - which were until now handled in the ABAP application layer - can be pushed down to the database layer.
- 6. Code to DATA
- 7. What is Coming with HANA? Unicode Only Integration with ‘R’ Large Tables Dynamic Tables ABAP Code Must be Optimized Eclipse based IDE (ADT) Optimization for Star Queries Signification Performance Improvements ALV paging for large results
- 8. CDS Views ABAP Core Data Services Define more complex view Only editing with ADT
- 9. AMDP Class The ABAP Development Tools (ADT) are better suited for the editing of database procedures in AMDP methods than Class Builderin ABAP Workbench. This means that AMDP classes can only be edited with the ABAP Development Tools (ADT). Currently, AMDP only supports database procedures from the SAP HANA database. In principle, however, AMDP is designed so that stored procedures from other database systems can also be supported. ABAP Developer can write Native SQLScript in method
- 10. ALV IDA The SAP List Viewer with Integrated Data Access offers application developers the option to use the in-memory database, such as SAP HANA, without having to switch to a new programming environment. End users can continue to work on the familiar interface The standard functions (also ALV services) that have been used in the ALV for a long time for executing calculations are still available in ALV with IDA. The new general programming model (CodingPushDown) is also optimally supported when using in-memory databases
- 11. ALV IDA SAP List Viewer ALV control is instantiated, and the container is assigned, and if required, the screen too. Data is selected with one or more SQL statements ( selectexpressions) and select options (WHERE clause) are transferred in the application program. A simple internal table with no deep structures is transferred to the ALV. SAP List Viewer with Integrated Data Access The ALV control is instantiated, and the container is assigned (and if required, the screen too) in the same way (see also,Embedding in SAP GUI) Select options (see Setting Selection Options) are transferred in ALV API. A more powerful Data Retrieval interface, such as Complex Conditions, and Text Search Across the Whole Table are available. The DDIC view/table name is transferred using the createmethod.
- 12. Benefits Does not impact transaction processing Enables “reporting without fear” by increasing reporting speeds dramatically Eliminates SAP as Access Loader Keeps processing within SAP and not Excel Avoid using old and/or partial data Convert batch processes to real-time operations Enable new big data processes
