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 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.






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






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






4. 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.






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






6. Dependency where determinant determines a list of values.






7. Knowingly violates one or more rules of normalization.






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






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






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






11. One or more fields whose values uniquely identify each record in a table.






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






13. 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.






14. Functional dependency involving only non-key attributes.






15. Stored procedures that may be configured to automatically execute (fire) when certain events take place.






16. The dominant database model






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






18. 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.






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






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






21. Data about data.






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 process of organizing data to minimize redundancy and produce smaller - well-structured relations/tables.






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






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






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






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






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






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






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






31. No Transitive Dependencies.






32. 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.






33. 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.






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






35. DOC MADE UP






36. 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.






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






38. All determinants are candidate keys.






39. A Key composed of more than one attribute.






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






41. 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.






42. 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.






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






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






45. The horizontal bar at the top of a column. You can click a column selector to select the entire column in the query design grid or the filter design grid






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






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






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






49. Candidate key selected for use.






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