What is a data dictionary?
What will be an ideal response?
A data dictionary is a repository of the metadata (data about the data) of the database. The data dictionary, also sometimes called the metadata repository, contains information such as the names of the tables, names and types of columns in them, the primary keys, referential integrity constraints, and so on. The metadata showing the structure of the functioning database system is automatically stored by the DBMS in the data dictionary.
