Development and Web Lang

• Software Development Life Cycle (SDLC) consists of distinct phases that collectively form the software development process
• Feasibility: Determine if the problem is solvable given current technology, time constraints, and costs
• Requirements: Identify what the finished system needs to do
• Analysis and Design: Work out how the system should accomplish its tasks
• Implementation: Write the actual code for the system
• Testing: Thoroughly test the code to ensure it works
• Deployment: Install the finished solution in the target environment
• Evaluation: Review the program with the user to ensure it meets all original needs and requirements
• Maintenance: Ensure the software continues to work by making improvements, patches, updates, and additional releases
• Five main software development methodologies to be aware of for the exam:
• Waterfall model: Phases have well-defined start and end points with identifiable deliverables
• Rapid Application Development (RAD): Produces successive prototypes until a final version is achieved
• Spiral model: Risk-driven software development process model that allows for flexibility in adopting elements of other methodologies
• Agile methodologies: Focus on iterative development to accommodate shifting requirements during the development process
• Extreme Programming: A framework that emphasizes high-quality code and promotes common practices like communication, feedback, and simplicity
