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






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






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






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






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






6. Data about data.






7. 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.






8. Dependency where determinant determines a list of values.






9. All key attributes defined - attributes depend on key and no repeating groups.






10. An action query that adds the records in a query's result set to the end of an existing table.






11. 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






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






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






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






15. 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.






16. A relation that contains no multivalued attributes.






17. 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.






18. 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






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






20. Attribute that determines the value of another attribute.






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






22. 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.






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






24. 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.






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






26. Table has no anomalies.






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






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






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






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






31. A Key composed of more than one attribute.






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






33. 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.






34. An abstract model that documents and organizes the business data for communication between team members and is used as a plan for developing applications - specifically how data is stored and accessed.






35. No partial functional-dependencies.






36. A graphical representation of all entity relationships (Data Model)






37. Functional dependency involving only non-key attributes.






38. 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.






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






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






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






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






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






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






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






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






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






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






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






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