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






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






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






4. Data about data.






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






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






7. A primary key that is comprised of more than one field.






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






9. 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






10. Functional dependency involving only non-key attributes.






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






12. 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.






13. 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.






14. No partial functional-dependencies.






15. 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






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






17. No multiple multi-valued dependencies.






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






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






20. 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.






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






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






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






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






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






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






27. a.k.a record






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






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






30. Attribute that determines the value of another attribute.






31. A collection of fields that together describe one entity.






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






33. 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.






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






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






36. 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.






37. 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.






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






39. Table has no anomalies.






40. The dominant database model






41. 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.






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






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






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






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






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






47. A database object that prints information formatted and organised according to your specifications.






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






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






50. 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.
