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






2. 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.






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






4. 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.






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






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






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






8. 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.






9. 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.






10. 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.






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






12. 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






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






14. Functional dependency involving only non-key attributes.






15. 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.






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






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






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






19. Data about data.






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






21. 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.






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






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






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






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






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






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






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






29. 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






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






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






32. a.k.a record






33. A control that indicates whether an option is selected or not. A tick mark appears in the box when the option is selected.






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






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






36. Knowingly violates one or more rules of normalization.






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






38. 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.






39. 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






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






41. All determinants are candidate keys.






42. 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.






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






44. 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.






45. 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.






46. Attribute that determines the value of another attribute.






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






48. A Key composed of more than one attribute.
