ABAP Data Dictionary (DDIC) Concepts
The ABAP Dictionary (DDIC) is a central metadata repository in SAP systems where developers define and manage data models used across ABAP applications. It stores definitions for database tables, data elements, domains, structured types, and table types that can be referenced throughout ABAP development. Developers use it to create reusable, consistent type definitions and to manage the structure of database objects without writing platform-specific SQL.
