Meaning of Logical Database

[Arthur Wang]

What is a ‘Logical Database’?

A ‘Logical Database’ is a special data-retrieval program delivered by SAP, with its own dynamic Selection Screens. You need to code only the processing logic (GET, CHECK, etc., statements).

The logical database consists of a ‘read’ program in which the structure of the local database is reproduced with a selection screen.

Advantages:

– Check functions to validate that user input is complete and correct.
– Meaningful data selection.
– Central authorization checks for database accesses.
– Excellent read access performance while retaining the hierarchical data view determined by the application logic.
