Software Architecture definitions and illustration
What is the software architecture
Software architecture of a system is the set of structures needed to reason about the system, which comprise system elements, relations among them, and properties of both. Software/System architecture typically refers to the bigger structures of a system, and it deals with how multiple systems processes cooperate to carry out their tasks. Software Design refers to the smaller structures and it deals with the internal design of a single software process.
Architecting a software describe the major components of the system with referring to how components of the system interact with each other.
Architecting a software and design includes several contributory factors such as Business strategy, quality attributes, human dynamics, design, and IT environment.
Software architecture and design are two related phases, where in architecture, nonfunctional decisions are cast and separated by the functional requirements and in design, functional requirements are accomplished.
Architecting a software and design are very related and each phase affect the another one. While the software architecture phase focus on bigger view of the system, the software design phase focus on internal subsystems/functions/components and how the software pieces work together.
Software architecture real life sample
Business case
- I supposed that the system will be built from scratch

- Flight
- Train
- Bus
- The system will support multi-languages (Arabic, English, French, German and Spanish)
