This simple example should provide some insight re: how we grouped our data.
GROUP 1 - Let’s say that we wanted to group PRACTICAL THINGS used by people everyday. We would first create a primary first level group.
We could identify major areas, such as Food, Shelter, Jobs, Recreation. For this example we will select Food.
First Level (category): FOOD
GROUP 2 - Next we would indentify groupings found under the food category, such as Milk, Meat, and Fruit. For this example we will choose FRUIT.
Second Level (category): FRUIT
GROUP 3 - Next we would indentify groupings found under the fruit category, such as Grapes, Apples, Bananas. For this example we will choose GRAPES.
Third Level (category): GRAPES
Details - Beneath the bottom level we would store various types of information related to grapes, such as planting, harvesting, packaging, and sales.
