Explain the three views of a database
The unique internal view of the database is the physical arrangement of records which describes the structure of data records, the linkages between files, and the physical arrangement and sequence of records in the file.
The unique conceptual view (or schema) represents the database logically and abstractly. This view allows users' programs to call for data without knowing or needing to specify how the data are arranged or where the data reside in the physical database.
The many user views (or subschema) define the portion of a database that an individual user is authorized to access. To the user, the user view is the database.
