14. 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






15. A relation that contains no multivalued attributes.






16. All determinants are candidate keys.






17. 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.






18. 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.

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






23. 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.






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






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






26. 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.






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






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






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






30. 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






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






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






33. 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






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






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






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






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






38. This is a property of data which - when satisfied - requires every value of one field (attribute) of a table to exist as a value of another field in another related table.






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






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






41. A graphical representation of any portion of a database scheme.






42. 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.






43. 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.






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

49. DOC MADE UP






50. 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.
