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 central repository for databases across an entire enterprise.






2. No multiple multi-valued dependencies.






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






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






5. Specialized engines designed specifically to store objects. Users can interact with objects only through designated methods.






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






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






8. A field - set up in a query - that displays the result of an evaluated expression rather than displaying stored data.The value of the calculated field is re-calculated each time a value in the expression changes.






9. 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.






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






11. 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.






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






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






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






15. Attribute that determines the value of another attribute.






16. Data from a table - form - query which is displayed in a row-and-column format.






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






18. 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.






19. A relation that contains no multivalued attributes.






20. Dependency where determinant determines a list of values.






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






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






23. A link between two or more tables.






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






25. 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






26. All determinants are candidate keys.






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






28. 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.






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






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






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






32. 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.






33. 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.






34. 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.






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






36. 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.






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






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






39. 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.






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






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






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






43. The dominant database model






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






45. 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






46. 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).






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






48. Data about data.






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






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