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 link between two or more tables.






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






3. A query that removes records which match the criteria you specify from one or more tables






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






5. No Transitive Dependencies.






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






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






9. DOC MADE UP






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






11. Attribute that determines the value of another attribute.






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






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






14. A Key composed of more than one attribute.






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






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






17. 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.






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






19. Data about data.






20. 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.






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






22. 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.






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






24. 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.






25. No multiple multi-valued dependencies.






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






27. 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






28. Dependency where determinant determines a list of values.






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






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






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






32. An operator used to compare two values or expressions; For example - < (less than) - > (greater than) - = (equal to)






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






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






35. No partial functional-dependencies.






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






37. Knowingly violates one or more rules of normalization.






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






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






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






41. 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






42. An MS Access tool that simplifies a task. For example - you can quickly create a complex expression with the Expression Builder.






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






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






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






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






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






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






49. The horizontal bar at the top of a column. You can click a column selector to select the entire column in the query design grid or the filter design grid






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