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. 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.






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






3. The window that appears when you open an Access database or an Access project. It displays the commands for creating new database objects and opening and manipulating existing objects.






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






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






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






8. 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.






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






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






11. A Key composed of more than one attribute.






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






13. A data model in which the data is organized into a tree-like structure. The structure allows representing information using parent/child relationships: each parent can have many children - but each child has only one parent






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






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






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






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






19. No partial functional-dependencies.






20. 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.






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






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






23. 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.






24. 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).






25. Knowingly violates one or more rules of normalization.






26. 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.






27. Table has no anomalies.






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






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






30. 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.






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






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






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






34. A type of computer file system that stores all data in a single file.






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






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






37. a.k.a record






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






39. Candidate key selected for use.






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






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






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






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






44. 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.






45. The process of examining and analyzing data with a view to extracting patterns from it. It is usually done on data warehouses






46. 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.






47. 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






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






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






50. 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.
