Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

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






2. 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.






3. 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.






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






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






6. 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.






7. 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






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






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






10. When a table is not only in 1NF but each non key field is functionally dependent on the full primary key






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






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






13. 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.






14. An attribute utilized to sort and/or identify data in some manner. Each table should have a primary key which uniquely identifies records.






15. The actual pieces of facts that are stored in the fields in a database table.






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






17. The conditional expession that is to be used to select particular data records from a larger set of records.






18. Candidate key selected for use.






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






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






21. To modify a database - or the files associated with the database.






22. Attribute that determines the value of another attribute.






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






24. 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.






25. 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.






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






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






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






29. A characteristic of the items in a database i.e. a field






30. 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.






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






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






33. Knowingly violates one or more rules of normalization.






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






35. A Key composed of more than one attribute.






36. A function such as sum - count or average that you use to include summary data in a report.






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






38. When a relation is not just in Boyce-Codd Normal Form - but also contains at most one multivalued dependency.






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






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






41. All determinants are candidate keys.






42. No multiple multi-valued dependencies.






43. Dependency where determinant determines a list of values.






44. DOC MADE UP






45. A link between two or more tables.






46. A value that is automatically entered in a field or control when you add a new record.






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






48. 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.






49. A DBMS created by Microsoft - it is a collection of data and objects - such as tables - queries - or forms - related to a particular topic or purpose.






50. A relation that contains no multivalued attributes.
