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 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.






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






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






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






5. 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.






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






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






8. 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.






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






10. 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.






11. Dependency where determinant determines a list of values.






12. A database object that prints information formatted and organised according to your specifications.






13. DBMS (Database Management System) statements used to manage data (tables and other objects) within a database






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






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






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






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






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






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






21. 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.






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






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






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






25. 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.






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






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






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






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






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






31. Functional dependency involving only non-key attributes.






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






33. 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.






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






35. No partial functional-dependencies.






36. 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.






37. 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






38. 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.






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






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






41. 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.






42. 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.






43. No Transitive Dependencies.






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






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






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






47. The conditional expession that is to be used to select particular data records from a larger set of records.






48. 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.






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