The goal of this project is to apply web based coding and SQL database technique to develop energy trace investigation system in order to support the Taipower internal department’s energy saving investigation.For company internal reporting procedure items,(1) charged department table format and database for usage of electricity, water, and gasline has to plan design and establish according to 11 individual department’s characteristic. (2)Besides, functions of operation procedure, input interface, ouput list format, system maintain and priviligy management for usage of electricity, water, and gasline need to be built.
In this paper, the competent units of requirements, design a simple data entry system, electric water and oil, users can quickly fill in electric energy consumption of water and oil projects. On site functions, testing has been finished for proposed developed system. The practicality and effectiveness of proposed developed system can be justified by testing results.
