2. 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.






3. Dependency where determinant determines a list of values.






4. 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






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






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






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






8. No partial functional-dependencies.






9. A query that displays a summary calculation - such as an average or a sum - for values in a table or tables. A totals query is not a seperate kind of query; rather it extends the flexibility of select queries.

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






25. 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).

27. Attribute that determines the value of another attribute.






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






29. 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.






30. Functional dependency involving only non-key attributes.






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






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






33. 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.
