Dictionary objects, Program ojects, etc are repository objects. All the objects which you can see thru SE84 are repository objects. Al repository objects are stored in the database tables. All these tables are cross client.

For perofrmance reason latest version of all last used repository objects are kept in the Applciation server buffer.

Hi,

The ABAP dictionary lies in the APPLICATION LAYER and is connected to the RDB - Relational Database.

But, the dictionary objects are the physical data which is present in the underlying DATABASE (Database Layer).

ABAP dictionary is designed to minimize the database access, improving the performance and support the complete working of the SAP.
