Describe the three components involved in deriving any new data type.
What will be an ideal response?
The following three components are involved in deriving any new data type:
• value space-The set of values that correspond to the data type. For example, the valuespace for a positiveInteger data type includes the numbers 1, 2, 3, etc., but not 0, negative integers, fractions, or text strings.
• lexical space-The set of textual representations of the value space. For example, a value supported by the floating data type, such as 42, can be represented in several ways, including 42, 42.0, or 4.2E01.
• facets-The properties that distinguish one data type from another. Facets can include such properties as text string length or a range of allowable values. For example, a facet that distinguishes the integer data type from the positiveInteger data type is the fact that positive integers are constrained to the realm of positive numbers.
