Construct Tree Structure for the first time is sometimes regarded as a “pain-staking” process but future usage will only require the user to Re-use the old Tree Structure by editing and saving it with another name. Thus the Tree Structure is commonly known as “Construct Once Reuse Forever”.

Important notes for the user in constructing a good Tree Structure:

1. Each Tree Structure is unique based on the user’s creativity and demand

2. It uses Parent and Child concept (User need to identify the Parents FIRST before inserting the Child)
