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






2. A location within a database table that stores one particular type of data i.e. a field






3. 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.






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






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






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






7. A Key composed of more than one attribute.






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






9. 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






10. 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.






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






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






13. 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.






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






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






16. Functional dependency involving only non-key attributes.






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






18. 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.






19. Knowingly violates one or more rules of normalization.






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






21. The dominant database model






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






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






24. Candidate key selected for use.






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






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






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






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






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






30. DOC MADE UP






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






32. 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.






33. 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.






34. 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






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






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






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






38. 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.






39. 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






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






41. 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.






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






43. 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.






44. 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.






45. Data about data.






46. Table has no anomalies.






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






48. An action query that adds the records in a query's result set to the end of an existing table.






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






50. No multiple multi-valued dependencies.
