And the third step is making a flowchart and entity relation diagram design, then perform database creation. The process of developing program is using PHP programming language, MySQL for database and for the forecasting calculation is using ARIMA method. Based on the result obtained from the testing, system can store inventory data, do forecasting calculation based on the sales data, displaying graphs of the result of forecasting, have a shortcut key to print forecasting report and do error calculation to get the smallest error from three methods so can be used to perform the best forecasting.
