Answer to Question 1

Metadata is data about the structure of the database itself. This includes data about the names of all the tables in the database, the names of all the columns in each of the tables, the data type of each column in each table, the properties of the tables and the columns, etc. Metadata accounts for the self-describing aspect of the definition of a database as a self-describing collection of integrated tables.
