Construction Phase in Object- Oriented System Analysis and Design (OOSAD)  1. Develop functional code based on system design. 2. Ensure quality through Topic testing at multiple levels. Learning Outcomes 3. Create documentation for future reference. 4. Prepare for implementation and deployment.  What is the Construction Phase? - THE PHASE WHERE DESIGNS - INVOLVES CODING, TESTING, - BRIDGES THE GAP BETWEEN ARE TRANSFORMED INTO AND INTEGRATION OF DESIGN AND ACTUAL CODE. COMPONENTS. IMPLEMENTATION.  Key Activities in the Construction Phase 1. Coding: Translating design into functional programming. 2. Testing: Ensuring each module meets requirements. 3. Integration: Combining modules into a cohesive system. 4. Documentation: Preparing manuals, reports, and guides.  Coding Practices Use modular coding for better readability and maintenance. Follow coding standards to ensure consistency. Implement error handling and logging. Focus on performance optimization.  Unit Testing Tests individual components of the system. Ensures each module performs as expected. Identifies and fixes errors early in development.  Integration Combines individual modules into subsystems. Resolves conflicts between modules. Tests interaction between components.  System Testing Validates the entire system against requirements. Tests for functionality, performance, and usability. Simulates real-world use cases.  Key Roles in the Construction Phase Developers: Write and debug code. Testers: Validate modules and the system. Project Managers: Monitor progress and address risks. Users: Provide feedback during testing.  Tools Used Development Tools: Visual Studio, Eclipse. Version Control: GitHub, GitLab. Testing Tools: JUnit, Selenium. Collaboration Tools: Trello, Jira.  Common Challenges 1. Debugging complex errors. 2. Meeting tight deadlines. 3. Ensuring compatibility between modules. 4. Maintaining high quality under pressure.  Importance of Documentation Code Documentation: Explains logic and functions. Testing Reports: Records all test cases and outcomes. User Manuals: Guides end-users on system operation. Deployment Guides: Details steps for system implementation.  Transition to Implementation Ensure all components pass system testing. Obtain user approval. Deploy the system in a live environment. Provide training for users and support teams.  Recap and Key Takeaways Construction Phase is about turning design into reality. Testing ensures reliability at all levels. Integration creates a unified system. Documentation and teamwork are crucial for success.  Questions and Discussion Open the floor for student questions. Encourage sharing of challenges faced in similar projects. Construction Phase in Object-Oriented System Analysis and Design (OOSAD) Diploma in IT Students  What is the Construction Phase? The phase where designs are transformed into actual code. Involves coding, testing, and integration of components. Bridges the gap between design and implementation.  Objectives of the Construction Phase 1. Develop functional code based on system design. 2. Ensure quality through testing at multiple levels. 3. Create documentation for future reference. 4. Prepare for implementation and deployment.  Key Activities in the Construction Phase 1. Coding: Translating design into functional programming. 2.

Encourage sharing of challenges faced in similar projects.  Importance of Standards in Construction Phase Ensures code consistency. Facilitates collaboration among team members. Improves maintainability of the system. Version Control in Construction Phase Tracks changes in the codebase. Facilitates teamwork by merging changes from multiple developers. Allows rollback to previous versions if issues arise.  Agile Practices in Construction Continuous integration and deployment. Frequent iterations for feedback. Collaboration with stakeholders.  Quality Assurance in Construction Phase Manual testing for user interface. Automated testing for repetitive tasks. Ensures reliability and performance.  Handling Errors and Debugging Use debugging tools (e.g., breakpoints, logs). Prioritize critical issues. Maintain error logs for future reference.  Continuous Integration (CI) Automates code integration. Detects integration issues early. Enhances collaboration across teams.  Performance Testing in Construction Phase Measures system speed and responsiveness. Identifies bottlenecks. Ensures scalability for high traffic.  Security Considerations Protect sensitive data. Implement authentication and authorization. Conduct vulnerability testing.  User Acceptance Testing (UAT) Ensures the system meets user needs. Involves real-world scenarios. Final validation before deployment.  Training and Knowledge Transfer Educate users on system functionalities. Provide comprehensive user manuals. Offer support during the transition period.  Case Study: Construction Phase Example Project: Library Management System. Components: Book checkout, user registration, inventory tracking. Tools: Python, GitHub, Selenium for testing.
