5.  SAP AG 2003, slide 5 ABAP Workbench vs. SAP Java IDE -+ Environment/Infrastructure -+ Support for SAP Technology +- Private Test Environment +- Offline Development +- Support for Standards +- Local Editing -+ Large Scale Application Support JAVAABAP Server-oriented Design and runtime objects stored in same database SAP System determines “scope ” Java Operates on Local File System Design and runtime objects separated Development environment organized in local “projects ”

6.  SAP AG 2003, slide 6 ABAP vs. Java: Some Highlights ABAP  One frame (SE80) for all design-time tools  Logistics seamlessly integrated into the Development Workbench Build environment, Deployment, Software Logistics, etc.  Supports SAP technologies Structured “logical,” not physical, presentation of all SAP design- time objects Java Local Development Environment  Editing support: Syntax Highlighting, Code Completion, etc.  Offline development  Private test environment (partially) Support for Standard Technologies  J2SE, J2EE, HTML, XML, etc.

7.  SAP AG 2003, slide 7 Goal: Combine the Advantages of Both Approaches Provide one frame for all tools and as integration point for all infrastructure components Provide convenient integrated infrastructure environment for large-scale application development Preserve the principle of local IDE Provide local editing support Enable offline development Support standard and SAP technologies Logically structure the presentation of design-time objects Enable graphical editing
