3. 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).

5. Table has no anomalies.






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

8. DOC MADE UP

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






20. 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.






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






22. A section of a record containing data relating to one single characteristic of an entity; also called an attribute






23. No Transitive Dependencies.






24. 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.






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






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






27. A graphical representation of entities and their relationship to each other - typically used in computing in regard to the organization of data within databases or information systems






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






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

37. All determinants are candidate keys.






38. A location within a database table that stores one particular type of data i.e. a field






39. No partial functional-dependencies.






40. Attribute that determines the value of another attribute.






41. 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.






42. A graphical representation of all entity relationships (Data Model)






43. Knowingly violates one or more rules of normalization.






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






45. 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.






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






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






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






49. 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.






50. Dependency where determinant determines a list of values.
