Oracle Metadata
The Oracle Database contains tables which describe what database objects – i.e. tables, procedures, triggers etc. – exist within the database. This information about the information is known as metadata.
Oracle metadata is information contained within the Oracle Database about the objects contained within the Oracle database. You can use this information to find all tables accessible by a user, get a list of stored procedures, and get information about many other types of objects in an Oracle database.
The ORACLE application server and Oracle relational database keep metadata in two areas: data dictionary tables (accessed via built-in views) and a metadata registry.

Famous quotes containing the word oracle:
“There be three things which are too wonderful for me, yea, four which I know not: the way of an eagle in the air; the way of a serpent upon a rock; the way of a ship in the midst of the sea; and the way of a man with a maid.”
—Bible: Hebrew Proverbs, 30:18-19.
From the oracle of Agur, son of Jakeh.
