Study Notes

Importance of Software Engineering

Software engineering provides models to measure and evaluate software quality, including models for estimating defects inserted and removed throughout the software lifecycle
It is necessary to handle big projects without problems, as it requires planning, direction, testing, and maintenance

Software Engineering vs Computer Science

Computer Science is concerned with theory and fundamentals, involving the understanding and application of both abstract and concrete knowledge
Software engineering is a field concerned with the application of engineering processes to the creation, maintenance, and design of software for various purposes

Why is Software Engineering necessary?

Cost: adapting to the appropriate process can lower the cost of programming
Dynamic nature: software constantly changes, requiring updates to existing software
Quality management: better software development procedures provide better quality software products

Characteristics of a Good Software Engineer

Familiarity with software engineering principles
Good technical knowledge of the project's domain
Good programming skills
Good communication skills
Security awareness
Ability to utilize a layered architecture with critical resources in the inner layers
Ability to locate safety-critical features in a small number of subsystems

Architecture

Multiple views or perspectives are useful in designing and documenting a system's architecture
Each architecture model shows only one view or perspective of the system
Notations should be used to describe architectural models

Architectural Patterns

Patterns are solutions to specific problems that occur recurrently in a given context
A pattern has three parts: Context, Problem, and Solution
Patterns are a means of representing, sharing, and reusing knowledge

Model-View-Controller (MVC) Pattern

Separates presentation and interaction from the system data
The system is structured into three logical components: Model, View, and Controller
Used when there are multiple ways to view and interact with data, and when future requirements for interaction and presentation of data are unknown
