Answer»

To read data from a database tables we use logical database. A logical database provides read-only access to a group of related tables to an ABAP/4 program.

Advantages:

  • check FUNCTIONS which check that user input is complete, correct,and plausible.
  • MEANINGFUL data SELECTION.
  • central authorization checks for database accesses.
  • good read access performance while retaining the hierarchical data view determined by the application logic.

dis advantages:

  • If you donot specify a logical database in the program attributes,the GET events never occur.
  • There is no ENDGET COMMAND,so the code block associated with an event ends with the next event statement (such as ANOTHER GET or an END-OF-SELECTION).
