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.
