Hi,

The ABAP Dictionary centrally describes and manages all the data definitions used in the system. The ABAP Dictionary is completely integrated in the ABAP Development Workbench. All the other components of the Workbench can actively access the definitions stored in the ABAP Dictionary.

The ABAP Dictionary supports the definition of user-defined types (data elements, structures and table types). You can also define the structure of database objects (tables, indexes and views) in the ABAP Dictionary. These objects can then be automatically created in the database with this definition. The ABAP Dictionary also provides tools for editing screen fields, for example for assigning a field an input help (F4 help).

Warm Regards,

Hi Minati,

Data definitions (metadata) are created and managed in the ABAP Dictionary. The ABAP Dictionary permits a central description of all the data used in the system without redundancies. New or modified information is automatically provided for all the system components. This ensures data integrity, data consistency and data security.

You can create the corresponding objects (tables or views) in the underlying relational database using these data definitions.

The data Dictionary therefore describes the logical structure of the objects used in application development and shows how they are mapped to the underlying relational database in tables or views.

The Dictionary also provides standard functions for editing fields on the screen, for example for assigning a screen field an input help.

Hi,

Central information repository for application and system data. The ABAP Dictionary contains data definitions (metadata) that allow you to describe all of the data structures in the system (like tables, views, and data types) in one place. This eliminates redundancy.

HI,

See for example we take a program and database tables for your library maintainence..

you have customers, books in library and customers hiring books daily..

now you need to create tables for this Bookmaster, customer master and transparent table for book+customer hiring.

You need data dictionary where you can creat tables, datatypes everything that is needed ..This data dictionary objects are global..Can be accessed by anyone in that server..

The main use is reusability..

If you decalre a data element in data dictionary sey customer numdber,,The other persons will be using them for their purpose..reusability..

So SAP Provided standard Tables, data elements in Data Dictionary for Business purpose..and there is lot of documentation .. try to find in SAP Forum the links..
