Study Notes
Software Engineering: Introduction
- Software engineering applies scientific principles to the design and creation of software.
- It uses a systematic approach to gather and analyze business needs to design, build, and test software applications.
- Software engineers use their skills in engineering, mathematics, and computing to solve real-world problems.
The Software Crisis
- A software crisis occurs when there's a mismatch between what software can deliver and user expectations.
- This mismatch was a growing problem in the 20th century.
- Pressure to create complex, advanced code often contributes to a software crisis.
The Solution: Software Engineering
- Software engineering aims to address the software crisis by following a more structured and scientific approach to software development.
Importance of Software Engineering
- It allows teams to manage complexity, improve efficiency, reduce errors, and ensure that software meets user needs.
Software Engineering Tasks
- Requirements Gathering: Understanding the needs of users and stakeholders.
- Software Design: Creating a blueprint for the software's architecture, components, and functionality.
- Implementation: Building the software using programming languages and tools.
- Testing: Checking for errors and ensuring the software meets requirements.
- Deployment: Making the software available to users.
- Maintenance: Fixing bugs, improving performance, and adding new features over time.
Skills Required for Software Engineering
-
Hard Skills:
- Programming languages (e.g., Python, Java, C++)
- Version control (e.g., Git)
- Cloud computing (e.g., AWS, Azure)
- Testing and debugging
- Monitoring and troubleshooting
- Agile development methodologies
- Database architecture
-
Soft Skills:
- Communication
- Problem-solving
- Teamwork
- Critical thinking
- Adaptability
Career Paths in Software Engineering
- Front-end Development: Creating the user interface and user experience of websites and applications.
- Back-end Development: Building the server-side logic, databases, and APIs that power applications.
- Full-Stack Development: Combining front-end and back-end skills.
- Software Architect: Designing the overall structure and architecture of complex software systems.
- Database Administrator: Managing and maintaining databases.
- DevOps Engineer: Automating and managing software development and deployment processes.
Software Types
- System Software: Provides core functionality for a computer system (e.g., operating systems, device drivers).
- Application Software: Software designed for specific tasks (e.g., word processors, browsers, games).
- Embedded Software: Software integrated into hardware devices (e.g., software in washing machines, cars).
- Web Applications: Software accessed over the internet (e.g., online banking, social media platforms).
- Mobile Applications: Software designed for smartphones and tablets.
Software Products
-
Generic Products: Stand-alone systems sold to any customer. Examples include:
- PC software (graphics programs, project management tools)
- CAD software
- Software for specific markets (appointment systems for dentists)
-
Customized Products: Software commissioned by a specific customer for their needs. Examples include:
- Embedded control systems
- Air traffic control software
- Traffic monitoring systems
Software Development Life Cycle (SDLC)
- Planning: Defining project scope, goals, and resources.
- Requirements Gathering: Identifying the specific needs and functionalities of the software.
- Design: Creating the software architecture, user interface, and data models.
- Development: Implementing the software using coding and programming.
- Testing: Ensuring quality and finding errors.
- Deployment: Making the software available to users.
- Maintenance: Ongoing support, bug fixes, and feature updates.
Software Processes
- Software Process: Encompasses methodologies, workflows, and management practices for developing, delivering, and maintaining software.
-
Software Process vs. SDLC:
- Scope: Software processes are broader, including management and quality control.
- Objectives: Software processes prioritize efficiency and effective management, while SDLC focuses on technical development.
- Components: Software processes include SDLC stages plus project management and quality assurance.
Important Notes
- The concepts presented are based on "Software Engineering, 10th Edition by Ian Sommerville."
- Chapter 1 covers the introduction to Software Engineering.
- Chapter 2 focuses on Software Processes and the SDLC.
- The text uses a lecture format, so the information is presented concisely with supporting examples.
