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 data type that is used for fields and calculations involving money






2. 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.






3. 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.






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






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






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






7. 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.






8. A characteristic of a field that determines what kind of data it can store and what type of operations can be performed on it.






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






10. 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.






11. Dependency where determinant determines a list of values.






12. 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.






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






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






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






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






17. Table has no anomalies.






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






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






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






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






23. No Transitive Dependencies.






24. 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.






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






26. 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.






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

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






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






34. DOC MADE UP






35. Attribute that determines the value of another attribute.






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






37. A Key composed of more than one attribute.






38. 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.






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






40. 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

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






47. No multiple multi-valued dependencies.






48. 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






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






50. 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).
