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






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






11. A data type that is used for fields and calculations involving money






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






13. 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.

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






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






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






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






27. 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.






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






29. A relation that contains no multivalued attributes.






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






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






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






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






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






36. No partial functional-dependencies.






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






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






39. a.k.a record

42. The process of organizing data to minimize redundancy and produce smaller - well-structured relations/tables.






43. 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.






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






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






46. A function such as sum - count or average that you use to include summary data in a report.






47. A candidate key that coud have been the primary key but was not selected as such ; OR a field that is not the primary key but has been used for indexing nevertheless.






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






49. Functional dependency involving only non-key attributes.






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