	Boolean datatype Summary and Analysis
		Boolean data are often distinguished from text, which consists of textual information stored in text files (files in which characters are represented by their ASCII codes).
		In computer science, the Boolean datatype, sometimes called the logical datatype, is a primitive datatype having one of two values: one and zero (which are equivalent to true and false, respectively).
		It is the special case of a binary numeric datatype...

	Boolean datatype - Wikipedia, the free encyclopedia (Site not responding. Last check: )
		In computer science the boolean datatype, sometimes called the logical datatype, is a primitive datatype having two values: one and zero (sometimes called true and false).
		It is the special case of a binary numeric datatype of only one digit, or bit, and can also be represented in any other radix by restricting the range of allowed values for certain operations.
		In the C programming language, there is no boolean type provided in the C89 (but there is one in C99), but instead true/false values are determined by comparing a value to zero.

	Boolean - Wikipedia, the free encyclopedia
		The adjective Boolean (sometimes boolean), coined in honor of George Boole, is used in many contexts:
		A boolean value is a truth value, either "true" or "false", often coded 1 and 0, respectively.
		In computer science, "boolean" is a datatype, usually a primitive datatype.

	Resource Description Framework (RDF): Concepts and Abstract Syntax
		Datatypes are used by RDF in the representation of values such as integers, floating point numbers and dates.
		The datatype abstraction used in RDF is compatible with the abstraction used in XML Schema Part 2: Datatypes [XML-SCHEMA2].
		For example, the QName datatype requires a namespace declaration to be in scope during the mapping, and is not recommended for use in RDF.

	RDF Datatyping
		As specified in [XSD], a canonical lexical representation is a set of elements from the lexical space of a datatype such that there is a one-to-one mapping between elements in the canonical lexical representation and elements in the value space.
		[Definition:] A canonical datatype mapping is a subset of a datatype mapping that establishes a one-to-one correspondence between elements in the canonical lexical representation and elements in the value space.
		To associate a datatype property with a certain datatype, the extension of the datatype property is defined to be the datatype mapping that belongs to the datatype.

	Boolean_datatype (Site not responding. Last check: )
		In computer science, the '''boolean datatype''', sometimes called the ''logical datatype'' is a primitive datatype having two values, ''one'' and ''zero'' (in English: '''true''' and '''false''').
		In the C programming language, there is no boolean type provided (true for C89, but not for C99), but true/false values are determined by comparing a value to zero.
		In the Visual Basic programming language, boolean values from comparisons can be stored in variables with the boolean data type, which is stored as a two-byte integer but can only have the values '''True''' and '''False'''.

	AskTom "Boolean Datatype" (Site not responding. Last check: )
		Clarity: if the value I'm trying to store really is a boolean, then when I'm glancing at my model, it's clear that that's what the column is. Sure, if it's a char(1) that's a good indication, but not a sure-fire one.
		BOOLEAN is a fundamental and natural datatype, and most databases I have known would use it liberally if it existed.
		I'm assuming a Boolean datatype would have to be tri-valued to fully support integration with PL/SQL and to be consistent with ANSI SQL.

	XML Schema Part 2: Datatypes Second Edition
		The ·lexical space· of a ·list· datatype is a set of literals whose internal structure is a space-separated sequence of literals of the ·atomic· datatype of the items in the ·list·.
		The canonical-lexical-representation for a ·union· datatype is defined as the lexical form in which the values have the canonical lexical representation of the appropriate ·memberTypes·.
		For example, a datatype could be defined to correspond to the [SQL] datatype Year-Month interval that required a four digit year field and a two digit month field but required all other fields to be unspecified.

	Oreview - PL/SQL Guru - March 1997
		Every time you use a Boolean, you encapsulate or hide a (potentially) complicated Boolean expression involving many different variables and tests behind a name that directly expresses the intention and meaning of the text.
		Although this statement is actually true for any identifier you define in PL/SQL, it has maximum impact with Booleans because they return a logical value and bring you closer to writing code that can be read as if it were a human rather than computer language.
		Just when you are thinking that life with Booleans is great, I have some bad news: The Oracle RDBMS does not support a Boolean datatype.

	Boolean value
		Boolean value, also known as boolean datatype, is a primitive datatype having two values: one and zero (sometimes called true and false).
		It is the special case of a binary numeric datatype of only one digit, or bit, and can also be represented in any other radix by restricting the range of allowed values for certain operations.
		This datatype is used in boolean and other operations such as and (AND, and, ), or (OR, , +), exclusive or/not equivalent (xor, NEQV, ^), equal (EQV, =, ==) and not (NOT, ~, !) which correspond to some of the operations of Boolean* algebra and arithmetic.

		Relying on implicit datatype conversions is a poor programming practice because they can be slower and the conversion rules might change in later software releases.
