Acronyms & Terminology

CORBA: Common Object Request Broker Architecture.

The Common Object Request Broker Architecture (CORBA) is a standard defined by the Object Management Group (OMG) that enables software components written in multiple computer languages and running on multiple computers to work together.

CORBA uses an interface definition language (IDL) to specify the interfaces that objects will present to the outside world. CORBA then specifies a mapping from IDL to a specific implementation language like C++ or Java. Standard mappings exist for Ada, C, C++, Lisp, Ruby, Smalltalk, Java, COBOL, PL/I and Python. There are also non-standard mappings for Perl, Visual Basic, Erlang, and Tcl implemented by object request brokers (ORBs) written for those languages.


General InterORB Protocol (GIOP)

Main article: General Inter-ORB Protocol

The GIOP is an abstract protocol by which Object request brokers (ORBs) communicate. Standards associated with the protocol are maintained by the Object Management Group (OMG). The GIOP architecture provides several concrete protocols, including:

1. Internet InterORB Protocol (IIOP) — The Internet Inter-Orb Protocol is an implementation of the GIOP for use over an internet, and provides a mapping between GIOP messages and the TCP/IP layer.
2. SSL InterORB Protocol (SSLIOP) — SSLIOP is IIOP over SSL, providing encryption and authentication.
3. HyperText InterORB Protocol (HTIOP) — HTIOP is IIOP over HTTP, providing transparent proxy bypassing.

How does a datasource communicates "DELTA" with BW?

Image
SAP R/3 or ECC DataSource Delta mechanism for SAP BW/BI What is Delta? It is a feature of the extractor which refers to the changes(new/modified entries)occured in the source system. How to identify? In ROOSOURCE table, key in the data source name and check the field "DELTA". If the field is left blank,it implies that the datasource is not delta capable. The field 0RECORDMODE in BW determines how a record is updated in the delta process. Now the question is how this delta will be brought to BW? Using one of the following ways: ABR: After before and Reverse image AIE: After image ADD: Additive image ABR: After before and Reverse image Example: Logistics What is it? Once a new entry was posted or an exiting posting was changed at R/3 side, an after image shows the status after the change, a before image shows the status before the change with a negative sign and the reverse image also shows the negative sign next to the record while indic...
