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. No partial functional-dependencies.






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






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






4. 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.






5. Attribute that determines the value of another attribute.






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






7. Knowingly violates one or more rules of normalization.






8. 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.






9. A control that indicates whether an option is selected or not. A tick mark appears in the box when the option is selected.






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






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






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






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






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






15. When a table is not only in 1NF but each non key field is functionally dependent on the full primary key






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






17. 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.






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






19. 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.






20. 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.






21. No multiple multi-valued dependencies.






22. 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.






23. A query that asks a question about the data stored in your tables and returns a results set in the form of a data sheet without changing the actual data in the table(s).






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






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






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






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






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






29. 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.






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






31. 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.






32. a.k.a record






33. 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






34. 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.






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






36. 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






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






38. A characteristic of the items in a database i.e. a field






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






40. No Transitive Dependencies.






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






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






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






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






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






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






47. All determinants are candidate keys.






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






49. 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.






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