Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. No partial functional-dependencies.






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






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






4. Knowingly violates one or more rules of normalization.






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






6. 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.






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






8. 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.






9. No multiple multi-valued dependencies.






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






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






12. A Key composed of more than one attribute.






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






14. 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






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






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






17. 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






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






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 conditional expession that is to be used to select particular data records from a larger set of records.






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






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






23. 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.






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






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






26. All determinants are candidate keys.






27. 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.






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






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






31. The dominant database model






32. 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.






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






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






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






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






37. 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.






38. 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.






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






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

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






43. DOC MADE UP






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