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






2. Data about data.






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 record as seen in the data sheet view.






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






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






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






8. 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.






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






10. A relation that contains no multivalued attributes.






11. Candidate key selected for use.






12. Knowingly violates one or more rules of normalization.






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






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






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






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






17. 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.






18. No Transitive Dependencies.






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






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






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






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






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






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






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






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






27. No partial functional-dependencies.






28. No multiple multi-valued dependencies.






29. 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.






30. 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.






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






32. Functional dependency involving only non-key attributes.






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






34. A database computer language designed for the retrieval and management of data in relational database management systems (RDBMS) - database schema creation and modification - and database object access control management.






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






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






37. 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.






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






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






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






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






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






43. 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.






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






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






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






47. a.k.a record






48. 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.






49. 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.






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