Data Dictionary

What is Data Dictionary?

1.

A data dictionary is (generally) a read-only set of tables and views that holds metadata - used in a database management system. The data dictionary may be considered a database in its own right.

Amongst other things, a Data Dictionary holds the following information:

* Usernames, Roles and Privileges

*Schema Objects

*IntegrityConstraints

*Stored procedures and Triggers

*General Database Structure

*Audit information

*Space allocations

One benefit of a well prepared data dictionary is a consistency between data items across different tables.

several tables may hold telephone numbers, using a data dictionary the format of this telephone number field will be consistent.
