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






2. A relation that contains no multivalued attributes.






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






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






5. 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.






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






7. A type of computer file system that stores all data in a single file.






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






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






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






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






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






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






14. DOC MADE UP






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






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






17. Functional dependency involving only non-key attributes.






18. 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.






19. 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.






20. 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.






21. 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.






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






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






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






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






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






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






28. The program which is used to organize - access and manage the data in a database - Creates - processes - and administers databases.






29. 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.






30. Dependency where determinant determines a list of values.






31. A link between two or more tables.






32. No multiple multi-valued dependencies.






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






34. 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.






35. 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






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






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






38. Data about data.






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






40. No Transitive Dependencies.






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






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






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






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






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






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






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






48. A function such as sum - count or average that you use to include summary data in a report.






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






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