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 location within a database table that stores one particular type of data i.e. a field






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






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






4. 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.






5. DOC MADE UP






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






7. All determinants are candidate keys.






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






9. A field in a table with unique values that although it is not the primary key - it could have been used as such.






10. Table has no anomalies.






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






12. A relational database management system from Microsoft that combines the relational MS Jet Database Engine with a graphical user interface and software-development tools.






13. 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.






14. A link between two or more tables.






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






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






17. A Key composed of more than one attribute.






18. 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.






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






20. Data about data.






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






22. 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.






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






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






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






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. 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.






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






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






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






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






32. 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.






33. 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.






34. A relation that contains no multivalued attributes.






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






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






37. Knowingly violates one or more rules of normalization.






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






39. a.k.a record






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






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






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






44. Attribute that determines the value of another attribute.






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






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






47. 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.






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






49. The process of examining and analyzing data with a view to extracting patterns from it. It is usually done on data warehouses






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