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






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






4. 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.






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






6. Knowingly violates one or more rules of normalization.






7. 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






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






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






11. 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.






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






13. One (or more fields) in a table that refer to the primary key in another table.






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






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






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






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






19. A graphical representation of any portion of a database scheme.






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






21. The dominant database model






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






23. No Transitive Dependencies.






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






25. DOC MADE UP






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






27. 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






28. The DBMS language component used to create - alter and destroy databases and database objects i.e. schemas - tables - views - sequences - catalogs - indexes - and aliases.






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






31. 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.






32. All determinants are candidate keys.






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






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






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






36. 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.






37. No multiple multi-valued dependencies.






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






39. 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.






40. 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.






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






42. 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.






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






44. 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.






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






46. Groups of database commands which are to be treated as a single atomic event.






47. 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.






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






49. Data about data.






50. 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
