1. 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






2. No Transitive Dependencies.






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






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






5. A relation that contains no multivalued attributes.






6. Attribute that determines the value of another attribute.






7. 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).






8. Refers to the number of associations that can exist between two record types.






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






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






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






13. 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.

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






16. A query that copies data or changes data in some way. This includes append - delete - make-table and update queries.






17. A Key composed of more than one attribute.






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






19. A combination of attributes that can be used to uniquely identify a database record. Candidate keys are a special subset of super keys that do not have any extraneous information in them






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






21. a.k.a record






22. A programming language designed for managing & obtaining data in relational database management systems (RDBMS)






23. Functional dependency involving only non-key attributes.






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






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






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






27. An operator used to compare two values or expressions; For example - < (less than) - > (greater than) - = (equal to)






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






29. A field in a table with unique values that although it is not the primary key - it could have been used as such.






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






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






32. 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.






33. Data from a table - form - query which is displayed in a row-and-column format.






34. An attribute utilized to sort and/or identify data in some manner. Each table should have a primary key which uniquely identifies records.






35. 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.






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






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






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






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






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






41. 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






42. 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.






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






44. 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 of0 - 1 - or many records in the related table.






45. No multiple multi-valued dependencies.






46. The persons or things that a database table is about.






47. A database object on which you place controls for entering - displaying and editing records in a table.






48. All determinants are candidate keys.






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






50. A control - also called an edit field - used on a form - report or data access page to display text or accept data entry.It can have a label attached to it.
