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






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






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






4. A relation that contains no multivalued attributes.






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






6. No Transitive Dependencies.






7. 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.






8. No multiple multi-valued dependencies.






9. The dominant database model






10. 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






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






12. 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.






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






14. Data about data.






15. 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.






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






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






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






19. A Key composed of more than one attribute.






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






21. 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.






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






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 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.






25. Candidate key selected for use.






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






27. 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






28. 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.






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






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






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






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






33. 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.






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






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






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






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






38. a.k.a record






39. Two or more controls that can be treated as one unit while designing a form or report. You can select the group instead of selecting each individual control as you are arranging controls or assigning properties.






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






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






42. The set of fields in a table which stores unique values and so any one from the list can be selected to be the primary key.






43. Stored procedures that may be configured to automatically execute (fire) when certain events take place.






44. 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.






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






46. 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.






47. 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.






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






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






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