Study Notes

What is Software?

Instructions that tell a computer how to perform tasks
Powers our digital world, from simple apps to complex operating systems

Types of Software

System Software: Manages computer hardware and provides a platform for applications
- Operating Systems (Windows, macOS, Linux)
- Device drivers
- Utilities
Application Software: Designed for specific tasks
- Word processors
- Web browsers
- Games
- Mobile apps
Programming Software: Tools for developers to create, debug, and maintain software
- Integrated Development Environments (IDEs)
- Compilers
- Debuggers

Importance of Software in Modern Society

Healthcare: Electronic Health Records, Diagnostic tools
Finance: Online banking, Trading algorithms
Transportation: GPS navigation, Traffic management
Education: E-learning platforms, Educational apps
Industry: Automation, Supply chain management

Timeline of Major Developments

1940s: Machine language programming
1950s: Assembly languages
1960s: High-level languages (COBOL, FORTRAN), first operating systems
1970s: Structured programming, software engineering concepts introduced
1980s: Object-oriented programming, personal computers
1990s: World Wide Web, Java programming language
2000s: Agile methodologies, open source movement
2010s: Cloud computing, mobile ecosystems
2020s: AI and machine learning integration, DevOps and continuous delivery

Key Milestones

1968: Term "software engineering" first used
1970: Winston Royce presents the Waterfall Model
1981: Rapid Application Development (RAD) developed
1995: Scrum and Extreme Programming (XP) introduced
2001: Agile Manifesto published
2009: DevOps movement begins

Evolution of Programming Paradigms

Unstructured Programming: Early days, no clear organization
Structured Programming: Emphasis on control structures and modularity
Object-Oriented Programming: Focus on objects containing data and code
Functional Programming: Emphasis on functions and immutable data
Aspect-Oriented Programming: Separation of cross-cutting concerns

What is a Software Development Methodology?

Structured approach to designing, creating, and maintaining software systems
Framework for organizing work and managing projects

Components of a Software Development Methodology

Phases: Distinct stages of development
Deliverables: Outputs produced at each phase
Roles: Responsibilities assigned to team members
Techniques: Methods for accomplishing tasks
Tools: Software and resources used to support the process

Overview of Different Methodologies

Plan-driven Methodologies:
- Waterfall Model
- V-Model
- Rational Unified Process (RUP)
Iterative and Incremental Methodologies:
- Spiral Model
- Rapid Application Development (RAD)
Agile Methodologies:
- Scrum
- Extreme Programming (XP)
- Kanban
Lean Software Development
DevOps

Waterfall Model

Linear sequential approach to software development
Each phase must be completed before the next begins
Emphasis on documentation
Simple and easy to understand
Well-defined stages
Works well for small projects with clear requirements
Inflexible to changes
Testing starts late in the development process
High risk and uncertainty

Classical Waterfall Model

Extension of the basic Waterfall Model
More phases for a comprehensive approach
