Answer to Question 1

Class or composition, combinations, expected values, missing data, pictures/templates, range, reasonableness, self-checking digits, size, and values are ten validation tests and techniques. The class or composition test checks to assure that data are of proper type. The combinations test checks to see if the value combinations of two or more data fields are appropriate or make sense. The expected values test checks to see if data are what is expected. The missing data test checks for existence of data items in all fields of a record. The pictures/templates test assures that data conform to a standard format. The range test assures that data are within a proper range of values. The reasonableness test assures that data are reasonable for a given situation. The self-checking digits test is a test where an extra digit is added to a numeric field in which its value is derived using a standard formula. Testing for too few or too many characters is referred to as a size test. A values test checks to make sure values come from a set of standard values.
