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 primary key that is comprised of more than one field.






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






3. Data about data.






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






5. 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.






6. Candidate key selected for use.






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






8. 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.






9. A relation that contains no multivalued attributes.






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






11. 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.






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






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






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






15. 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.






16. Functional dependency involving only non-key attributes.






17. A query ( SQL statement ) that creates a new table and then creates records in it by coping records from an existing table.






18. 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.






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






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






21. 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.






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






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






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






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






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






27. 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.






28. A query that asks a question about the data stored in your tables and returns a results set in the form of a data sheet without changing the actual data in the table(s).






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

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






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






39. The DML statement used to choose data from a database. The result is stored in a temporary table - called the result-set.






40. 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.






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






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






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






44. 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.






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






46. 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






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






48. No Transitive Dependencies.






49. 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.
