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






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






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






4. 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.






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






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






7. All determinants are candidate keys.






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






9. 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.






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






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






12. 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.






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






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






15. a.k.a record






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






17. 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






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






19. That structure which contains description of objects created by a user - such as base tables - views and constraints - as a part of a database.






20. Knowingly violates one or more rules of normalization.






21. 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.






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






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






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






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






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






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






28. 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






29. 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






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






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






32. 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.






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






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






35. DOC MADE UP






36. Dependency where determinant determines a list of values.






37. No multiple multi-valued dependencies.






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






39. Table has no anomalies.






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






41. 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.






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






43. No Transitive Dependencies.






44. 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.






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






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






47. A Key composed of more than one attribute.






48. Candidate key selected for use.






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






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