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






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






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






4. No partial functional-dependencies.






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






6. 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






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






8. The set of fields in a table which stores unique values and so any one from the list can be selected to be the primary key.






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






10. 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.






11. The dominant database model






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






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






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






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






16. 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.






17. 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.






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






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






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






21. A relation that contains no multivalued attributes.






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






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






24. Knowingly violates one or more rules of normalization.






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






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






27. Dependency where determinant determines a list of values.






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






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






30. 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.






31. 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.






32. 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.






33. 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.






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






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






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






37. 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.






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






39. Candidate key selected for use.






40. 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).






41. 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.






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






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






44. 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.






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






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






47. 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






48. 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.






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






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