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






2. 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.






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






4. All determinants are candidate keys.






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






6. Arrange the records in a view set in order according to a particular field






7. 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.






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






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






10. The dominant database model






11. 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.






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






13. No multiple multi-valued dependencies.






14. 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.






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






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






17. A database computer language designed for the retrieval and management of data in relational database management systems (RDBMS) - database schema creation and modification - and database object access control management.






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






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






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






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






22. 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.






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






24. 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.






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






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






27. 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.






28. 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.






29. 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






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






31. Refers to the number of associations that can exist between two record types.






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






33. Dependency where determinant determines a list of values.






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






35. 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.






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






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






38. Attribute that determines the value of another attribute.






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






40. 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.






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






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






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






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






45. A value that may be assigned to an attribute when no other value applies or when the applicable value is unknown.






46. Candidate key selected for use.






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






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






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






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.
