6. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 6 § Software design It is responsible for the code level design: what each class is doing, its relationships, and scope. § Software architecture It is responsible for the skeleton and the high-level organization of a software. It identifies the main structural modules (or components) in a system and the relationships between them. Definition
7. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 7 § Define separate branches for each major function § Coordinate communication between modules § Limit propagation of side effects § Facilitate extensibility, modifiability and reuse Architecture Goals
