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






2. A Key composed of more than one attribute.






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






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






5. 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






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






7. Knowingly violates one or more rules of normalization.






8. A relation that contains no multivalued attributes.






9. 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






10. 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.






11. A window that shows the design or structure of the database objects: tables - queries - forms - reports - macros and data access pages.






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






13. A way of looking at a database object - usually looking at the design or at the contents/results






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






15. 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.






16. No multiple multi-valued dependencies.






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






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






19. Attribute that determines the value of another attribute.






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






21. 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.






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






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






24. The program which is used to organize - access and manage the data in a database - Creates - processes - and administers databases.






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






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






27. A DBMS created by Microsoft - it is a collection of data and objects - such as tables - queries - or forms - related to a particular topic or purpose.






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






29. No Transitive Dependencies.






30. 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.






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






32. 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.






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






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






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






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






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






38. DOC MADE UP






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






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






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






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






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






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






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






46. 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






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






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






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






50. The DML statement used to choose data from a database. The result is stored in a temporary table - called the result-set.
