2. One or more fields whose values uniquely identify each record in a table.






3. Data from a table - form - query which is displayed in a row-and-column format.






4. A candidate key that coud have been the primary key but was not selected as such ; OR a field that is not the primary key but has been used for indexing nevertheless.






5. Groups of database commands which are to be treated as a single atomic event.






6. Functional dependency involving only non-key attributes.






7. a.k.a record






8. A field - set up in a query - that displays the result of an evaluated expression rather than displaying stored data.The value of the calculated field is re-calculated each time a value in the expression changes.






9. The set of fields in a table which stores unique values and so any one from the list can be selected to be the primary key.






10. A window that displays the SQL statement for the current query or is used to create a SQL specific query. When you create a query in design view - Access constructs the SQL equivalent in the SQL view.






11. The components of a data abase i.e. tables - queries - forms - reports - pages - macros and modules.






12. In an access databse - a window in which you work with tables in design view or datasheet view.






13. The DBMS language component used to create - alter and destroy databases and database objects i.e. schemas - tables - views - sequences - catalogs - indexes - and aliases.






14. The persons or things that a database table is about.






15. An operator used to compare two values or expressions; For example - < (less than) - > (greater than) - = (equal to)

17. This is an exact numeric data type that holds from 10^38 - 1 through 10^38 - 1.






18. All determinants are candidate keys.






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






20. A database object on which you place controls for entering - displaying and editing records in a table.






21. A graphical representation of any portion of a database scheme.

24. A control that indicates whether an option is selected or not. A tick mark appears in the box when the option is selected.






25. Many-to-many relationships occur when each record in TableA may have 0 - 1 or many linked records in TableB and vice-versa.






26. All key attributes defined - attributes depend on key and no repeating groups.






27. The window that appears when you open an Access database or an Access project. It displays the commands for creating new database objects and opening and manipulating existing objects.

46. A query that displays a summary calculation - such as an average or a sum - for values in a table or tables. A totals query is not a seperate kind of query; rather it extends the flexibility of select queries.
