Software Engineering II

Lecture 1: Software Design Concepts and Principles

Software Design

It encompasses the set of principles, concepts, and practices that lead to the development of a high-quality system or product.

Design principles establish and override the philosophy that guides the designer as the work is performed.

Design concepts must be understood before the mechanics of design practice are applied.

practices change continuously as new methods, better analysis, and broader understanding evolve

Data/Class Design

transform analysis classes into implementation classes and data structures.

Architectural Design

defines relationships among the major software structural elements

Interface Design 

defines how software elements, hardware elements, and end-users communicate

Component-level design 

transform structural elements into a procedural description of software components
