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. Arrange the records in a view set in order according to a particular field






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






3. Functional dependency involving only non-key attributes.






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






5. The dominant database model






6. 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






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






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






9. 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.






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






11. Stored procedures that may be configured to automatically execute (fire) when certain events take place.






12. 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.






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






14. 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.






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






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






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






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






19. No partial functional-dependencies.






20. 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






21. To modify a database - or the files associated with the database.






22. An operator used to compare two values or expressions; For example - < (less than) - > (greater than) - = (equal to)






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






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






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






26. Data about data.






27. 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.






28. 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.






29. 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






30. Table has no anomalies.






31. 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.






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






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






34. 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.






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






36. 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.






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






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






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






40. 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.






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






42. 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.






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






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






45. A link between two or more tables.






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






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






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






49. One or more fields whose values uniquely identify each record in a table.






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