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






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






3. 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






4. 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.






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






6. The actual pieces of facts that are stored in the fields in a database table.






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






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






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






10. Knowingly violates one or more rules of normalization.






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






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






14. Attribute that determines the value of another attribute.






15. 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.






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






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






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






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






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






21. A feature that speeds up searching and sorting in a table based on key values and can enforce uniqueness on the rows of a table.






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






23. 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).






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






25. A query ( SQL statement ) that creates a new table and then creates records in it by coping records from an existing table.






26. No partial functional-dependencies.






27. a.k.a record






28. 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.






29. A relation that contains no multivalued attributes.






30. 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.






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






32. Contents of a Database: Tables of user data - Metadata - Indexes - Stored Procedures - _______ - Security Data - Backup/Recovery Data






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






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. Data about data.






36. 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.






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






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






39. 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.






40. 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






41. 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.






42. Candidate key selected for use.






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






44. Dependency where determinant determines a list of values.






45. 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






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






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






48. 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.






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






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