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






2. Dependency where determinant determines a list of values.






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






4. Candidate key selected for use.






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






6. All determinants are candidate keys.






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






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






9. 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).






10. A characteristic of a field that determines what kind of data it can store and what type of operations can be performed on it.






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






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






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






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






15. 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.






16. Functional dependency involving only non-key attributes.






17. 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.






18. 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.






19. 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.






20. 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.






21. 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






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






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






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






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






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






27. a.k.a record






28. A query ( SQL statement ) that creates a new table and then creates records in it by coping records from an existing table.






29. 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






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 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.






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






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






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






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






36. 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






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






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






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






40. Specialized engines designed specifically to store objects. Users can interact with objects only through designated methods.






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






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






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






44. A key that consists of 2 or more attributes that uniquely identify an entity occurrence.






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






46. 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.






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






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






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






50. 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.
