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






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






4. The DML statement used to choose data from a database. The result is stored in a temporary table - called the result-set.

7. A window that shows the design or structure of the database objects: tables - queries - forms - reports - macros and data access pages.






8. A question about the data stored in your tables - or a request to perform an action on the data. A query can bring together data from multiple tables to serve as the source of data for a form. report or data access page.






9. No multiple multi-valued dependencies.






10. A primary key that is comprised of more than one field.






11. A central repository for databases across an entire enterprise.






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

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






15. Knowing the value of one attribute you can determine the value of another attribute.

17. Data about data.






18. The dominant database model






19. A type of computer file system that stores all data in a single file.

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






24. 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.






25. A value that may be assigned to an attribute when no other value applies or when the applicable value is unknown.






26. 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.

28. A location within a database table that stores one particular type of data i.e. a field

37. Relations which allow you to retrieve related records from the same table.






38. An association between two tables in which the primary key value of each record in the primary table corresponds to the value in the matching field or fields of0 - 1 - or many records in the related table.






39. A database object that prints information formatted and organised according to your specifications.






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






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






42. A self-describing collection of integrated tables. The tables are called integrated because they store data about the relationships between the rows of data.






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






44. A link between two or more tables.






45. A data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children - but each child has only one parent






46. A query that copies data or changes data in some way. This includes append - delete - make-table and update queries.






47. Table has no anomalies.






48. A table which is not only in 2NF but whose non-primary key fields are dependent only on the primary key and therefore have no dependence on (relationship to) any other non-primary key field in the table.






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






50. Two or more controls that can be treated as one unit while designing a form or report. You can select the group instead of selecting each individual control as you are arranging controls or assigning properties.
