Answer Posted / paramjeet
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: i)check functions which check that user input is
complete, correct,and plausible. ii)Meaningful data
selection. iii)central authorization checks for database
accesses. iv)good read access performance while retaining
the hierarchical data view determined by the application logic.
dis advantages: i)If you donot specify a logical database in
the program attributes,the GET events never occur. ii)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).
