### Version Control Systems

```bash
# Git Commands
git init                    # Initialize repository
git clone <url>            # Clone remote repository
git add <file>             # Stage changes
git commit -m "message"    # Commit changes
git push                    # Push to remote
git pull                    # Pull from remote
git branch                  # List branches
git checkout <branch>       # Switch branch
git merge <branch>          # Merge branch
```

### Package Managers

```bash
# Node.js (npm)
npm install <package>       # Install package
npm install -g <package>    # Install globally
npm update                  # Update packages
npm run <script>            # Run script

# Python (pip)
pip install <package>       # Install package
pip install -r requirements.txt  # Install from file
pip list                    # List installed packages
pip freeze > requirements.txt    # Save dependencies

# Java (Maven)
mvn clean install           # Clean and build
mvn dependency:resolve      # Resolve dependencies
mvn test                    # Run tests
mvn package                 # Create JAR
```

## Software Development Lifecycle

### Planning Phase

* Requirements gathering
* Feasibility analysis
* Project planning
* Resource allocation

### Design Phase

* System architecture design
* Database design
* User interface design
* API design

### Development Phase

* Coding according to specifications
* Unit testing
* Code review
* Integration testing

### Testing Phase

* System testing
* User acceptance testing
* Performance testing
* Security testing

### Deployment Phase

* Production deployment
* User training
* Documentation
* Maintenance planning

## Best Practices

### Code Quality

* Follow coding standards and conventions
* Write readable and maintainable code
* Use meaningful variable and function names
* Add comprehensive comments and documentation

### Testing

* Write unit tests for all functions
* Implement integration tests
* Use test-driven development (TDD)
* Maintain high test coverage

### Security

* Validate all inputs
* Use parameterized queries
* Implement proper authentication and authorization
* Regular security audits and updates

### Performance

* Optimize algorithms and data structures
* Use caching strategies
* Implement lazy loading
* Monitor and profile performance

## Software Architecture Patterns

### Monolithic Architecture

* Single application with all functionality
* Easy to develop and deploy
* Harder to scale and maintain
* Suitable for small to medium applications

### Microservices Architecture

* Multiple small, independent services
* Better scalability and maintainability
* More complex deployment and monitoring
* Suitable for large, complex applications

### Event-Driven Architecture

* Services communicate through events
* Loose coupling between components
* Asynchronous processing
* Suitable for real-time applications

### Layered Architecture

* Separation of concerns in layers
* Presentation, business logic, data access
* Easy to understand and maintain
* Common in enterprise applications
