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. All determinants are candidate keys.






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






3. Table has no anomalies.






4. A Key composed of more than one attribute.






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






6. Knowingly violates one or more rules of normalization.






7. 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.






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






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






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






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






12. 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.






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






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






15. 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.






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






17. A graphical representation of entities and their relationship to each other - typically used in computing in regard to the organization of data within databases or information systems






18. 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.






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






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






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






22. A section of a record containing data relating to one single characteristic of an entity; also called an attribute






23. DOC MADE UP






24. A collection of fields that together describe one entity.






25. 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.






26. A database computer language designed for the retrieval and management of data in relational database management systems (RDBMS) - database schema creation and modification - and database object access control management.






27. A record as seen in the data sheet view.






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






29. Attribute that determines the value of another attribute.






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






31. 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.






32. An organised pool of related data files which can be easily accessed and managed and that may be used by a number of different application programs






33. A relation that contains no multivalued attributes.






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






36. The dominant database model






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






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






39. 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.






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






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






42. The part of an SQL statement that specifies which record to retrieve.






43. A feature that speeds up searching and sorting in a table based on key values and can enforce uniqueness on the rows of a table.

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






49. 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.






50. a.k.a record
