This paper presents a database system of the rubber tree leaf diseases which compiled into a Personal Home Page (PHP) script and using Structured Query Language (MySQL). In this work, there are three selected diseases that can be identified using this database system which are Corynespora Leaf Spot, Bird’s Eye Spot and Collectrotichum Leaf Disease. Initially, the information of Region of Interest (ROI) from each of these three types of diseases based on Red, Green and Blue (RGB) color model from previous experiments will be taken as the input to the database system. By using PHP, a server-side language which sends Web pages to requesting visitors (you, the client, with your Web browser). When a visitor goes to a website written in PHP, the server reads the PHP code and then processes it according to its scripted directions. The client also able to fill in the data through the system online and the database system output will identify the diseases based on user data input. The purpose of development of this system is to help new users to identify the types of rubber tree leaf diseases whereby it is consists of data collection, stored and kept organized by the Database Management System. Therefore, by using the database system, this may assist the client on identifying the diseases by comparing their records with the available information. While the advantage of this system is it may help new users to study the characteristics of the diseases without referring to the expertise since the information is consists of sample of images and its symptoms.
