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






2. DOC MADE UP






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






4. 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.






5. Two or more controls that can be treated as one unit while designing a form or report. You can select the group instead of selecting each individual control as you are arranging controls or assigning properties.






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






7. All determinants are candidate keys.






8. A question about the data stored in your tables - or a request to perform an action on the data. A query can bring together data from multiple tables to serve as the source of data for a form. report or data access page.






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






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






11. 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.






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






13. 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






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






15. When a relation is not just in Boyce-Codd Normal Form - but also contains at most one multivalued dependency.






16. 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






17. Data about data.






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






19. A value that is automatically entered in a field or control when you add a new record.






20. 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






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






22. 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.






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






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






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






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






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






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






29. 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.






30. Relations which allow you to retrieve related records from the same table.






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






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. No partial functional-dependencies.






34. A link between two or more tables.






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






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






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






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






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






40. 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.






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






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






43. 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.






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






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






46. 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






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






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






49. Dependency where determinant determines a list of values.






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