OO ABAP + Performance

120 Views

Hi all…

I have recently started working in an organization as an ABAP programmer. Earlier, as part of my curriculum, I have designed a couple of systems using UML and coded the same in JAVA. Having worked on OO systems, I have a few questions to ask about ABAP and Web AS.

1) Does a company implementing SAP 6.0/ECC 6 have to decide in advance whether it will be coding its business logic/applications in JAVA or ABAP? Or Wes AS can process both languages once installed.

2) If a program is written in OO ABAP as well as in JAVA for a given business scenario (using the same OO (UML) structure) and executed on a Web AS, which one will perform better? Why?

3) Why is it that organizations, in spite of the visible benefits of OO programming, are unwilling to let go of procedural ABAP and adapt OO ABAP? Anyways, they don’t have to convert their existing code but just to begin any new development using OO concepts. Is it because programs written in ABAP are usually not that complex to be modeled in OO concepts or there are not many people who know both ABAP and OO concepts.
