Study Notes

Background and Purpose of Software Engineering

Software engineering aids the development of larger, multifunctional software systems.
Addresses challenges from equipment analysis to maintenance using systematic management techniques.

Key Elements of Successful Software Engineering

Process: Systematic approach using defined business methods and workflows.
People: Involves specialized knowledge within the organization.
Technology: Infrastructure and tools necessary for the effective operation of processes and personnel.

Historical Development of Software Engineering

1950s: The concept of software engineering began, paralleling hardware engineering.
1960s: Emergence of software engineering due to the "software crisis", linked to a shortage of skilled engineers.
1970s: Increased demand for software led to a "coding first, correction later" approach due to scarcity of developers.

Four Key Elements of Software Engineering

Method: Encompasses project planning, system analysis, coding, testing, and maintenance focused on software quality standards.
Tool: Tools like modeling and change management bolster productivity by automating tasks.
Procedure: Combines methods and tools to ensure rational development, quality control, and milestone tracking.
People: Human resources are vital in software design and development.

Lifecycle of Software Development

Process includes feasibility review, development planning, requirement analysis, design, implementation, testing, operation, and maintenance.
Purpose: To assess project costs, plan development, standardize terminology, and manage projects effectively.

Software Lifecycle Models

Select models based on risk and uncertainty, aiming to minimize both.
Common models: Waterfall, prototype, evolutionary, incremental, V-Model.

V Model Characteristics

Clearly defines project activities for managers and developers.
Facilitates customer understanding of software development.
Emphasizes verification and validation of requirements.

Prototyping

A method to develop parts of a system to clarify requirements and address uncertainties.
Can be a standalone model or integrated within other methodologies.

Software Development Methodologies

Incremental: Eases development time while allowing for continuous requirements refinement.
Evolutionary: Repeated development phases yield complete systems progressively.
Spiral: Combines iterative and incremental approaches for more structured risk management.
Agile: Includes frameworks like Scrum and XP for adaptive project management.

Agile Methodologies

Scrum: Structured around roles (Product Owner, Scrum Master, Scrum Team) with core practices like sprints and daily meetings to maintain transparency.
Extreme Programming (XP): Focuses on iterative development alongside Lean and Agile practices.
Lean: Prioritizes resource efficiency and minimal waste in development.

Software Development Methodology (SDM)

Defines phases, activities, deliverables, and quality assurance processes for software projects.
Enhances productivity, project management, communication, and quality assurance.

Software Development Phases

Requirement Analysis: Crucial for understanding user needs, reducing future costs.
Design: Impacts the software’s quality and stability significantly.
Implementation: Involves translating designs into functioning code while adhering to coding standards.
Testing: Validates if requirements are met through systematic evaluation.

SCT Constraints

Scope, Cost, and Time constrain software projects affecting delivery and success.

SMART Criteria for Project Goals

Specific, Measurable, Attainable, Realistic, Time-bound criteria ensure clarity in project objectives.

Software Quality Attributes

Usability: User-friendly interfaces facilitating efficient task completion.
Efficiency: Optimal use of system resources.
Reliability: Consistent performance without failure.
Maintainability: Ease of updates and alterations.
Reusability: Modular components can be used across various projects.

Terminology

CRUD: Basic operations (Create, Read, Update, Delete) in databases.
API: Interface for software components to communicate.
Entity: Represents a package containing classes (e.g., Student, Course).
Repository: Contains interfaces for data access.
Service: Handles business logic and CRUD operations.
Controller: Manages API endpoints for interaction.
