5. The process of organizing data to minimize redundancy and produce smaller - well-structured relations/tables.






6. Candidate key selected for use.






7. An organised pool of related data files which can be easily accessed and managed and that may be used by a number of different application programs






8. A query ( SQL statement ) that creates a new table and then creates records in it by coping records from an existing table.






9. Refers to the number of associations that can exist between two record types.

13. That structure which contains description of objects created by a user - such as base tables - views and constraints - as a part of a database.






14. Specialized engines designed specifically to store objects. Users can interact with objects only through designated methods.






15. A relational database management system from Microsoft that combines the relational MS Jet Database Engine with a graphical user interface and software-development tools.
