Using Logical Database Names
When you connect to a database, Progress automatically assigns that database a default logical name for the current Progress session. Progress uses the logical database name to resolve database differences, and stores it in the compiled r-code of any procedures that you compile that refer to the database. Logical database names allow you to change physical databases without recompiling an application.
Use logical database names to maintain consistency in naming conventions when porting your applications to other platforms.
