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






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






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






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






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






6. 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.






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






8. 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.






9. The dominant database model






10. 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.






11. A Key composed of more than one attribute.






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






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






14. Table has no anomalies.






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






16. 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.






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






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






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






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






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






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






23. 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.






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






25. 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






26. Dependency where determinant determines a list of values.






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






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






29. No Transitive Dependencies.






30. All determinants are candidate keys.






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






32. A relation that contains no multivalued attributes.






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






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






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






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






37. Functional dependency involving only non-key attributes.






38. No multiple multi-valued dependencies.






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






40. 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.






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






42. A self-describing collection of integrated tables. The tables are called integrated because they store data about the relationships between the rows of data.






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






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






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






46. 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.






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






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






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






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