With the help of DDIC, we can create and maintain user-defined types, such as data elements, structures, table types, etc.

As a view of the SQL, the ABAP dictionary handles the DDL (Data Definition Language) part of SQL that contains the commands, such as CREATE Table, DROP Table, ALTER Table, Create index, etc.
