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






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






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






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






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






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






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






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






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






10. The dominant database model






11. One (or more fields) in a table that refer to the primary key in another table.






12. 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.






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






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






15. 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 of one and only one record in the related table.






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






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






18. 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.






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






20. A Key composed of more than one attribute.






21. 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.






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






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






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






25. 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






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






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






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






29. Dependency where determinant determines a list of values.






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






31. 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.






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






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






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






35. An association/link established between common fields in two different tables. A relationship can be one-to-one - many-to-many or more usually one-to-many.






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






37. 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.






38. 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).






39. Functional dependency involving only non-key attributes.






40. The part of an SQL statement that specifies which record to retrieve.






41. 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.






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






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






44. A link between two or more tables.






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






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






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






48. 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.






49. All determinants are candidate keys.






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