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






2. 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.






3. 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.






4. No partial functional-dependencies.






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






6. Dependency where determinant determines a list of values.






7. 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.






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






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






10. 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.






11. Data about data.






12. Contents of a Database: Tables of user data - Metadata - Indexes - Stored Procedures - _______ - Security Data - Backup/Recovery Data






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






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






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






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






17. 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.






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






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






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






21. No Transitive Dependencies.






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






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






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






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






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






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






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






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






30. 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.






31. Functional dependency involving only non-key attributes.






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






33. 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.






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






35. a.k.a record






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






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






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






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






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






41. Candidate key selected for use.






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






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






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






45. 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






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






47. Knowingly violates one or more rules of normalization.






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






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