Logical Data[[image:http://www.veganlibrarian.com/LIBR287/George_Boole.jpg width="240" height="251" align="right" caption="Mathamatician"]]

 * Also called "Boolean" or "Yes or No" data.
 * This only has two choices that you can choose from.
 * E.g. Yes/No Good/Bad Present/Absent
 * Boolean Algebra
 * This is a branch of maths that solves logic problems with math and is widely used in the designing of computers.
 * The Boolean main 'operators' are:
 * A __and__ B: Statement is true if both A and B are true
 * A __or__ B: Statement is true if A or B are true
 * A __not__ B : Statement is true if A and NOT B are true
 * Boolean Search
 * Boolean searches put key words together using logic statement to link them together and it makes your search more efficient.
 * For example:
 * Strawberry shortcake AND food: You might use this if you were looking for how the two terms were related because all the searche results would have to have both terms in them.
 * Strawberry shortcake OR food: This would produce search results with either of the terms.
 * Strawberry shortcake NOT food: This is a statement to make your search more specific so that you can exclude the seaches you dont want, so that you wouldnt get search results about shortcake the food.

Alphanumeric Data

 * Also called "text" data.
 * It can include numbers, words and symbols but it does not necessarily HAVE to, it could be words only.
 * E.g. Telephone numbers, Adresses, Car number plates and Names

Numeric Data

 * As it's name states, numeric data is data in the form of numbers.
 * There are two types of numeric data:
 * Real. This means the numbers include fractions as well.
 * Integer: These numbers have to be whole, with no decimals, fractions or little bits left over, and they acn be positive or negative.

Date Data

 * This data is for dates only.
 * However, you can not have dates that have been made up, for example: 42nd of May 2010.
