Studies on efficiency of the data access by ABAP programming

Abstract

Currently, the implementation of the integrated information systems in companies represents a sine qua non condition for providing higher and more reliable accessibility to the information resources. One of the most used integrated platform is SAP Netweaver, a multilingual & multitasking system based on the three-tier client-server technology. The development environment is the Application Server ABAP and/or Java. This paper provides a series of studies performed to optimise the processing codes of the data found in the related tables in SAP Netweaver Application Server ABAP. To access the data from the persistence level tables, we use, in the ABAP codes, the Open SQL instructions, which represent a subset of the standard SQL instructions. © 2013 Springer-Verlag Berlin Heidelberg.
