What is the ABAP Data Dictionary?
ABAP Data Dictionary, also known as DDIC, is a central repository in the SAP system where all the metadata related to the database objects are stored. The DDIC is used to manage and maintain the definitions of the database objects such as tables, views, structures, data elements, domains, and search helps.
- The ABAP Data Dictionary provides a graphical user interface (SE11) for developers to create, change, and maintain the database objects and also provides a set of APIs for programmatic access to the metadata stored in the DDIC.

- The DDIC also plays an important role in ensuring data consistency and integrity by enforcing referential integrity constraints and by providing support for data types and data domains.
- Additionally, the ABAP Data Dictionary provides tools for generating database-independent ABAP code, which helps to simplify database migrations and improve the portability of SAP applications.
