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. All determinants are candidate keys.






2. 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.






3. The dominant database model






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






5. DOC MADE UP






6. 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.






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






8. Attribute that determines the value of another attribute.






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






11. 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






12. An operator used to compare two values or expressions; For example - < (less than) - > (greater than) - = (equal to)






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






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






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






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






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






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






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






20. No partial functional-dependencies.






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






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






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






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






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






26. Knowingly violates one or more rules of normalization.






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






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






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






30. A relation that contains no multivalued attributes.






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






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






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






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






35. 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.






36. 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).






37. 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.






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






39. The part of an SQL statement that specifies which record to retrieve.






40. 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.






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






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






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






44. 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






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






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






47. 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






48. 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.






49. 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.






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