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






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






3. 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.






4. 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.






5. 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.






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






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






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






9. The dominant database model






10. 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.






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






12. 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.






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






14. 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.






15. Dependency where determinant determines a list of values.






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






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 link between two or more tables.






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






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






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






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






23. Functional dependency involving only non-key attributes.






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






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






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






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 of one and only one record in the related table.






28. 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.






29. No partial functional-dependencies.






30. Attribute that determines the value of another attribute.






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






32. 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.






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






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






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






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






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






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






39. A data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children - but each child has only one parent






40. A record as seen in the data sheet view.






41. A control - also called an edit field - used on a form - report or data access page to display text or accept data entry.It can have a label attached to it.






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






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






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






45. Candidate key selected for use.






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






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






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






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






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