10. An association between two tables in which several records in one table can relate to 0 - 1 or many records in the other table.






11. A control - also called an edit field - used on a form - report or data access page to display text or accept data entry.It can have a label attached to it.






12. A field in a table with unique values that although it is not the primary key - it could have been used as such.

20. All determinants are candidate keys.






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

31. Table has no anomalies.






32. A way of looking at a database object - usually looking at the design or at the contents/results






33. A referential integrity constraint is a statement that limits the values of the foreign key to those already existing as primary key values in the corresponding table.






34. DBMS (Database Management System) statements used to manage data (tables and other objects) within a database

36. A data type that is used for fields and calculations involving money

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






48. This is a property of data which - when satisfied - requires every value of one field (attribute) of a table to exist as a value of another field in another related table.
