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. Table has no anomalies.






2. 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.






3. 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.






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






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






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






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






8. No partial functional-dependencies.






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






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






11. 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.






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






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






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






15. 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).






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






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






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






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






20. 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






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






22. 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.






23. All determinants are candidate keys.






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






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






26. Knowingly violates one or more rules of normalization.






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






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






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






30. Data about data.






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






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






33. 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






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






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






36. a.k.a record






37. 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






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






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






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






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






43. Candidate key selected for use.






44. 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.






45. 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.






46. A Key composed of more than one attribute.






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






48. No Transitive Dependencies.






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






50. 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.
