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






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






3. All determinants are candidate keys.






4. Data about data.






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






6. A link between two or more tables.






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






8. Candidate key selected for use.






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






10. Functional dependency involving only non-key attributes.






11. Specialized engines designed specifically to store objects. Users can interact with objects only through designated methods.






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






13. No partial functional-dependencies.






14. Knowingly violates one or more rules of normalization.






15. a.k.a record






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






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. No Transitive Dependencies.






19. 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.






20. 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






21. Attribute that determines the value of another attribute.






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






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






24. 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.






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






26. 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.






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






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






29. A relation that contains no multivalued attributes.






30. 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.






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






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






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






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






35. 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.






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






37. The dominant database model






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






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






40. 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.






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






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






43. 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.






44. No multiple multi-valued dependencies.






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






46. 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.






47. 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.






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






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






50. A Key composed of more than one attribute.
