This research work is done to optimize the search in hierarchal database by using Quad Tree. Quad Tree is a tree which consists of a node having 4 sub child nodes. Quad Tree is used in many fields such as computer graphics to find out a desired pixel in graphics and collision detection in 3-D gaming. There are various other applications of quad tree in different fields like weather forecasting, geographical survey and study of mutation rate with a change of environment. The main focus of this work was optimizing the search for which the main areas of concentration were various searching techniques using Quad Tree and finding out the best solution. To fulfill the purpose, a new approach is designed which results in better representation of data and enhancing the speed of search. This work is done on the basis of the value of the root node. Further based on this value, the ranges of nodes at each level are calculated. The results are also included with snapshots and comparison is given between earlier and proposed techniques.
