An individual item could be, for example, a //person// (e.g. pupil in a class), a //day// (if weather records were being collected), a //vehicle// (in a traffic survey) or anything else. The individual cards are known as **records**.

On each record card are a number of pieces of information relating to that individual - the data itself. Each piece of information is called a **field** and there could be any number of fields from one upwards, although typically there will be between six and twenty in most databases.

With this information you can then  · sort the records into any order, · display count graphs of data as bar or pie charts, · search for records matching specific criteria

These databases often require yes/no answers. They can be used to classifiy shapes, people in our class etc...It is a progressive elimination untill one item is left. Branch Tree databases
