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.

1. 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.






2. 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






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






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






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






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






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






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






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






10. 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






11. 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.






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






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






14. 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.






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






16. No partial functional-dependencies.






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






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. DBMS (Database Management System) statements used to manage data (tables and other objects) within a database






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






21. Attribute that determines the value of another attribute.






22. Knowingly violates one or more rules of normalization.






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






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






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






26. 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






27. 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.






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






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






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






31. 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.






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






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. No multiple multi-valued dependencies.






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






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






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






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






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






40. Functional dependency involving only non-key attributes.






41. 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.






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






43. a.k.a record






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






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






46. All determinants are candidate keys.






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






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






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






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