The document discusses software architecture, including its definition, types of architectures, views, and documentation. It defines software architecture as the fundamental organization of a system, including its components, relationships, and design principles. The document outlines different types of architectures like business, technical, and enterprise architectures. It also discusses common architecture views used in frameworks like RUP, RM-ODP, and DODAF. Finally, it covers architecture documentation and modeling techniques.

17. Architecture vs. Design non-functional requirements (“ilities”) functional requirements (domains) Important : this is a general guideline – sometimes the borders are blurred Architecture: where non-functional decisions are cast, and functional requirements are partitioned Design: where functional requirements are accomplished architecture design
