  • 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.

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






2. A link between two or more tables.






3. 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.






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






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






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






7. No partial functional-dependencies.






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






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






11. The part of an SQL statement that specifies which record to retrieve.






12. DOC MADE UP






13. Functional dependency involving only non-key attributes.






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






15. 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.






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






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






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






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






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






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






22. 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).






23. An MS Access tool that simplifies a task. For example - you can quickly create a complex expression with the Expression Builder.






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






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






26. 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.






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






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






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






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






31. 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






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






33. A Key composed of more than one attribute.






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






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






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






37. A central repository for databases across an entire enterprise.






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






39. 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.






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






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






42. 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.






43. All determinants are candidate keys.






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






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






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. The persons or things that a database table is about.






48. 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






49. This is a property of data which - when satisfied - requires every value of one field (attribute) of a table to exist as a value of another field in another related table.






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