🔧 Software Engineering Fundamentals
Software engineering is the systematic approach to designing, developing, and maintaining software systems.
Software Quality Metrics
The overall quality of software:
Quality = (Functionality + Reliability + Usability + Efficiency) / 4
Where each factor is measured on a scale of 0 to 100.
Maintainability Index
The maintainability of software code:
MI = 171 - 5.2 × ln(aveV) - 0.23 × aveC - 16.2 × ln(aveLOC)
Where aveV is average cyclomatic complexity, aveC is average comment ratio, and aveLOC is average lines of code.
Reliability Function
The reliability of software over time:
R(t) = e^(-λt)
Where λ is failure rate and t is time.
🔧 Key Insight: Software engineering ensures the development of reliable, maintainable, and efficient software systems through systematic processes and best practices.
