Software Development Essentials: Myths, Models, and Maintenance
Debunking Software Myths
Hardware is not more important than software. Software development is not just programming; it’s a complex process. Errors in software are common but manageable.
Software Lifecycle Models
Waterfall Model
Each phase produces an output that serves as input for the next. Variants differ in how they define phases.
Stages:
- Analysis: Define user needs and create the Software Requirement Document (SRD).
- Design: Organize the system and create the Software Design Document (SDD).
- Coding:

This involves using programs for computer literacy, focusing on basic computer concepts and programming languages.
Use as a Medium
The computer becomes an integrated educational resource within the curriculum.
- Learning from the computer: Using software designed for specific content learning.
- Learning with the computer: Facilitating cognitive development
