This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. An association between two tables in which several records in one table can relate to 0 - 1 or many records in the other table.






2. 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.






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






4. 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.






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






6. Candidate key selected for use.






7. Contents of a Database: Tables of user data - Metadata - Indexes - Stored Procedures - _______ - Security Data - Backup/Recovery Data






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






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






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






11. The process of examining and analyzing data with a view to extracting patterns from it. It is usually done on data warehouses






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






13. No partial functional-dependencies.






14. One (or more fields) in a table that refer to the primary key in another table.

16. A programming language designed for managing & obtaining data in relational database management systems (RDBMS)






17. A key that consists of 2 or more attributes that uniquely identify an entity occurrence.






18. All determinants are candidate keys.






19. 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

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






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






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






29. 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 of one and only one record in the related table.






30. Arrange the records in a view set in order according to a particular field






31. Stored procedures that may be configured to automatically execute (fire) when certain events take place.

33. The program which is used to organize - access and manage the data in a database - Creates - processes - and administers databases.






34. A combination of attributes that can be used to uniquely identify a database record. Candidate keys are a special subset of super keys that do not have any extraneous information in them






35. 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.






36. A field data type that automatically stores a unique number for each record as it is added to a table.






37. Attribute that determines the value of another attribute.






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

43. Guidelines set in place to ensure the trustworthiness of data over its entire life cycle.






44. 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.






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






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






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






48. 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.






49. A database object that stores data in records and fields. The data is usually about a particular category of things.






50. A normalization which falls between 3NF and 4NF and involves the elimination of non-trivial dependencies
