1. Specialized engines designed specifically to store objects. Users can interact with objects only through designated methods.






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






3. DOC MADE UP






4. A link between two or more tables.






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






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






7. A relation that contains no multivalued attributes.






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






9. DBMS (Database Management System) statements used to manage data (tables and other objects) within a database






10. 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






11. All determinants are candidate keys.






12. The dominant database model






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






14. No multiple multi-valued dependencies.






15. To modify a database - or the files associated with the database.






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






17. 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.






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






19. 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.






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






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






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






23. 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.






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






25. 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.






26. a.k.a record






27. 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.






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






29. 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.






30. 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






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






32. 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






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






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






35. 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.






36. Data about data.






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






38. Attribute that determines the value of another attribute.






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






40. Table has no anomalies.






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






42. 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.






43. An action query that adds the records in a query's result set to the end of an existing table.






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






45. 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.






46. Dependency where determinant determines a list of values.






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






48. A query that removes records which match the criteria you specify from one or more tables






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






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