Software engineering is an engineering approach for software development. In order to develop large software several phases has to be followed by the developer to achieve good quality software; cost effectively. System Design is the most important activity in software development which reflects reusability. System Design specifies what a new or modified system is going to do. To achieve good quality software, the primary characteristics of neat module decomposition are low coupling {data coupling}, high cohesion {functional cohesion} and top-down approach has to be followed. We applied these principles on developing Online Attendance System and observed reusability of code. The system has been successfully tested in our institute. Effective design principles always lead to an effective reusability which in turn benefited with Return on Investment (ROI).
