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. An attribute utilized to sort and/or identify data in some manner. Each table should have a primary key which uniquely identifies records.






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






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






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






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






6. A Key composed of more than one attribute.






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






8. A link between two or more tables.






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






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






11. 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.






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






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






14. 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.






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






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






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






18. a.k.a record






19. A relation that contains no multivalued attributes.






20. 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.






21. 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.






22. 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






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






24. 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.






25. 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.






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






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






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. Functional dependency involving only non-key attributes.






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






31. 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.






32. Many-to-many relationships occur when each record in TableA may have 0 - 1 or many linked records in TableB and vice-versa.






33. A query that copies data or changes data in some way. This includes append - delete - make-table and update queries.






34. 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.






35. 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.






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

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






41. Knowingly violates one or more rules of normalization.






42. Candidate key selected for use.






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






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






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






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






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






48. All determinants are candidate keys.






49. 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






50. No partial functional-dependencies.
