Abstract or Description
As the size and complexity of software systems increase, the design, specification, and analysis of overall system structure becomes a critical issue. Structural issues include the organization of a system as a composition of components; global control structures, the protocols for communication, synchronization, and data access; the assignment of functionality to design elements; the composition of design elements; physical distribution; scaling and performance, and dimensions of evolution. This is the software architecture level of design.
