1. An association between two tables in which several records in one table can relate to 0 - 1 or many records in the other table.






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






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






4. Contents of a Database: Tables of user data - Metadata - Indexes - Stored Procedures - _______ - Security Data - Backup/Recovery Data






5. 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.






6. 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.






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






8. 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






9. This is an exact numeric data type that holds from 10^38 - 1 through 10^38 - 1.






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






11. A table which is not only in 2NF but whose non-primary key fields are dependent only on the primary key and therefore have no dependence on (relationship to) any other non-primary key field in the table.






12. Candidate key selected for use.






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






14. Attribute that determines the value of another attribute.






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






16. The process of examining and analyzing data with a view to extracting patterns from it. It is usually done on data warehouses






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






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






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






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






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






22. The DBMS language component used to create - alter and destroy databases and database objects i.e. schemas - tables - views - sequences - catalogs - indexes - and aliases.






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






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






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






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






27. 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.






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






29. 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






30. 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.






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






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






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






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






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






36. 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.






37. A link between two or more tables.






38. No multiple multi-valued dependencies.






39. 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.






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






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






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






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






44. Dependency where determinant determines a list of values.

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






49. 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.
