Difference between Transparent Table and Pooled Table in SAP ABAP

Transparent Table:

• Defined at a database table level.
• Each Transparent Table corresponds to a table in the underlying database.
• Data stored in Transparent Tables are client-specific.
• Transparent Tables have a 1:1 mapping with the database table.

Pooled Table:

• Shared by multiple clients within the same system (client-independent).
• Group of data records from different clients stored together.
• Pooled Tables do not have a direct link to a database table.
• Memory-efficient as they reduce the number of database tables.
