1. 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).






2. Dependency where determinant determines a list of values.






3. No Transitive Dependencies.






4. a.k.a record






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






6. 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.

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






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






11. 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.






12. 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






13. 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.






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






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

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






26. A Key composed of more than one attribute.

32. 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.






33. 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.






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






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






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






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






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






39. A value that may be assigned to an attribute when no other value applies or when the applicable value is unknown.

45. No partial functional-dependencies.






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