A.2.3 Data Dictionary Notes
Definition
Data Dictionary
A centralized repository that stores metadata about the data in a database.
To be more specific, a data dictionary acts as a reference guide for database administrators, developers, and users.
It does this by providing essential information about the structure, constraints, and relationships within the database.
Note
The data dictionary does not store the actual data but describes the data stored in the database.
Key Components of a Data Dictionary
Table Names: The names of all tables in the database.
Field Names: The names of all fields (columns) within each table.
