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. Attribute that determines the value of another attribute.






2. Functional dependency involving only non-key attributes.






3. 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.






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






5. Knowingly violates one or more rules of normalization.






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






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






8. 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






9. 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.






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






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






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






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






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






15. 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.






16. DOC MADE UP






17. 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.






18. 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.






19. 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.






20. A Key composed of more than one attribute.






21. A query that asks a question about the data stored in your tables and returns a results set in the form of a data sheet without changing the actual data in the table(s).






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






23. 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






24. 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.






25. Candidate key selected for use.






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






27. A relation that contains no multivalued attributes.






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






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






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






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






32. A normalization which falls between 3NF and 4NF and involves the elimination of non-trivial dependencies






33. 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.






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






35. 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






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






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






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






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






40. 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.






41. 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.






42. 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






43. 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.






44. A data type that is used for fields and calculations involving money






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






46. Table has no anomalies.






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






48. Many-to-many relationships occur when each record in TableA may have 0 - 1 or many linked records in TableB and vice-versa.






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






50. The dominant database model
