Meanwhile, the manual method so far has its attendant problem of being tedious. However, SSADM as the research methodology was used which means structured system analysis and design methodology which is an internationally accepted software engineering model mainly used in most result oriented analysis. Also, the system was developed using HTML, PHP, and MSQL because of its capability user-friendly, etc. the system will automate the manual process of supermarket management. Finally, the parallel changeover methodology was adopted to enable the commission to compare the results of the two systems (old and new) before implementation.
