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 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.






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






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






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






5. a.k.a record






6. 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.






7. No multiple multi-valued dependencies.






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






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






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






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






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






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






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. A relation that contains no multivalued attributes.






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






17. The dominant database model






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






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






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






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






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






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






24. 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.






25. A window that shows the design or structure of the database objects: tables - queries - forms - reports - macros and data access pages.






26. Knowingly violates one or more rules of normalization.






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






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






29. Table has no anomalies.






30. 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.






31. 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.






32. Functional dependency involving only non-key attributes.






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






34. A candidate key that coud have been the primary key but was not selected as such ; OR a field that is not the primary key but has been used for indexing nevertheless.






35. Data about data.






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






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






38. All determinants are candidate keys.






39. 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






40. 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.






41. Candidate key selected for use.






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






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






44. The process of organizing data to minimize redundancy and produce smaller - well-structured relations/tables.






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






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






47. 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.






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






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






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