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. Dependency where determinant determines a list of values.






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






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






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






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






7. 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.






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






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






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






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






12. 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






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






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






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. Functional dependency involving only non-key attributes.






17. All determinants are candidate keys.






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






19. 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).






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






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






22. No Transitive Dependencies.






23. 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.






24. Attribute that determines the value of another attribute.






25. 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.






26. a.k.a record






27. 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.






28. 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.






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






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






31. 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






32. 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.






33. Candidate key selected for use.






34. Data about data.






35. 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.






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






37. 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.






38. 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






39. 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.






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






41. Table has no anomalies.






42. 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.






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






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






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






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






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






48. A Key composed of more than one attribute.






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






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