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






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






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






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






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






6. No Transitive Dependencies.






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






8. 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.






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






10. Knowingly violates one or more rules of normalization.






11. Data about data.






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






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






14. 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.






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






16. 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.






17. 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






18. 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.






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






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






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






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






23. 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.






24. The set of fields in a table which stores unique values and so any one from the list can be selected to be the primary key.






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






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






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






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






29. Attribute that determines the value of another attribute.






30. 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.






31. DOC MADE UP






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






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






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






35. 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.






36. 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.






37. 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






38. A link between two or more tables.






39. A relation that contains no multivalued attributes.






40. Relations which allow you to retrieve related records from the same table.






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






42. 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.






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






44. The process of organizing data to minimize redundancy and produce smaller - well-structured relations/tables.






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






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






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






48. All determinants are candidate keys.






49. A Key composed of more than one attribute.






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