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 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).






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






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






4. 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






5. 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






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






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






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






9. 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






10. Table has no anomalies.






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






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






13. 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.






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






15. 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.






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






17. 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.






18. 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.






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






20. Functional dependency involving only non-key attributes.






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






22. Attribute that determines the value of another attribute.






23. All determinants are candidate keys.






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






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






26. 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.






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






28. 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.






29. 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.






30. a.k.a record






31. The horizontal bar at the top of a column. You can click a column selector to select the entire column in the query design grid or the filter design grid






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






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






34. A Key composed of more than one attribute.






35. Dependency where determinant determines a list of values.






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






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






38. 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






39. 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.






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






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






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






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






44. A relation that contains no multivalued attributes.






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






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






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






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






50. The dominant database model
