Comprehensive Report: Defect Life Cycle and System Design in Software

This report delves into the critical aspects of the defect life cycle within software development, providing a comprehensive overview of system analysis, feasibility studies, and software design. It explores the Software Development Life Cycle (SDLC) model, hardware and software requirements, and various feasibility considerations, including technical, operational, and economic aspects. The report also covers the selected software, specifically Java, HTML, JavaScript, and JDBC, explaining their functionalities and significance in web-based applications and database connectivity. Furthermore, it encompasses system architecture, SDLC methodology, input and output design, data flow diagrams, UML diagrams (use case, class, sequence, and activity diagrams), and database structures. The report concludes with implementation details, screenshots, testing methodologies (unit, integration, and acceptance testing), and potential future enhancements.
