Web-based Hpa-an City Telephone Directory by implementing B-tree Database

Abstract

A directory is an essential part of people’s lives today. By accessing static directories like the paper phone books, people can easily find out phone numbers of other people, shops, organizations etc. But, all information in the paper directories is static and does not change in real time. So, conventional applications and paper works were instituting with web-based application. Online directory is necessary for modern lifestyle and have the capacity to be much more up-to-date. And, more amount of information can be added to an online directory like the organization, department in which that person works or the location of his/her office etc. In computer science, b-tree is a tree data structure that keeps data sorted, allows search, insertion, deletion and sequential access in logarithmic amortized time and the special thing about B-trees is that they are designed for really huge indexed databases. The system build web-based telephone directory of Hpa-an (local city of Myanmar) by implementing B-tree database. B-tree results are shown as according to b-tree’s operations (searching, inserting, and deleting) with user’s wanted information. There will be b-tree’s operation time, b-tree’s traveled nodes, and size of b-tree in b-tree results. And, apache tomcat 6.0.26 server is used as web service in the system.
