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






2. 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.






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






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






5. a.k.a record






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






7. 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.






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






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






10. Dependency where determinant determines a list of values.






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






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






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






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






15. A Key composed of more than one attribute.






16. No multiple multi-valued dependencies.






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






18. Candidate key selected for use.






19. 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






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






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






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






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






25. 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.






26. Groups of database commands which are to be treated as a single atomic event.






27. A relation that contains no multivalued attributes.






28. All determinants are candidate keys.






29. 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).






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






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






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






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






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






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






36. Data about data.






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






38. 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.






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






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






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






42. The dominant database model






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






44. Functional dependency involving only non-key attributes.






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






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






47. 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.






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






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






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