Aula ao vivo 02 - Engenharia de Software - 27/08/2024 - 19h00 - 19h50

Introduction

This tutorial provides a step-by-step guide based on the second live class on Software Engineering conducted on August 27, 2024. It covers key concepts and methodologies essential for understanding software engineering, making it relevant for students and professionals looking to enhance their skills in this field.

Step 1: Understanding Software Engineering Principles

• Definition: Software engineering is the application of engineering principles to software development in a methodical way.
• Key Principles:
  • Modularity: Break down software into smaller, manageable parts.
  • Abstraction: Use simplified models to manage complexity.
  • Encapsulation: Hide the internal state of objects to protect data integrity.

Practical Tips:

• Always start with a clear understanding of the project requirements.
• Use diagrams to visualize the architecture of the software.

Step 2: Software Development Life Cycle (SDLC)

• Phases of SDLC:
  1. Planning: Define the scope and purpose of the project.
  2. Analysis: Gather requirements and analyze feasibility.
  3. Design: Create system architecture and design specifications.
  4. Implementation: Write and test the code.
  5. Maintenance: Update and fix software post-deployment.

Common Pitfalls:

• Skipping the planning phase can lead to scope creep.
• Neglecting testing during implementation may result in undetected bugs.

Step 3: Agile Methodologies

• Overview: Agile focuses on iterative development, where requirements and solutions evolve through collaboration.
• Key Agile Practices:
  • Scrum: A framework for managing complex projects with iterative cycles called sprints.
  • Kanban: Visualize work and manage flow to improve efficiency.

Real-World Applications:

• Use Agile methodologies to adapt quickly to changing requirements in software projects.

Step 4: Version Control Systems

• Importance: Version control systems (VCS) help track changes and collaborate on code.
• Popular VCS Tools:
  • Git: A distributed version control system widely used in the industry.
  • SVN: Centralized version control system.

Basic Git Commands:

git init          # Initialize a new Git repository
git clone [url]   # Clone an existing repository
git add [file]    # Stage changes for commit
git commit -m "message"  # Commit changes with a message
git push          # Push changes to the remote repository

Conclusion

In summary, understanding software engineering principles, the software development life cycle, Agile methodologies, and version control systems are crucial for successful software development. By following these steps, you can enhance your software engineering skills and apply them to real-world projects. For further study, consider exploring advanced topics like DevOps practices and software testing strategies.
