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. 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.






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






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






4. No Transitive Dependencies.






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






6. Table has no anomalies.






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






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






9. A link between two or more tables.






10. The dominant database model






11. No partial functional-dependencies.






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






13. 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.






14. Dependency where determinant determines a list of values.






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






16. 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.






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






18. 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.






19. 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.






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






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






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






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






24. All determinants are candidate keys.






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






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






27. Candidate key selected for use.






28. 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).






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






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






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






32. 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






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






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






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






36. A value that may be assigned to an attribute when no other value applies or when the applicable value is unknown.






37. a.k.a record






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






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






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






41. 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.






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






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






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






45. 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.






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






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






48. 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






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. Functional dependency involving only non-key attributes.
