Answer to Question 2
There are two general phases of design formulation that can be distinguished:
(1 ) architectural design and (2 ) detailed design. Architectural design occurs immediately after requirements analysis and before detailed design. An architectural design is concerned with structural, functional, and behavioral issues of a system by modeling the problem and the outline solution. Structural issues that influence design decisions include organization and control structures; communication, synchronization, and data access protocols; physical distribution of functions of design elements; future developments, and so on.
Critical architectural design decisions are made in early stages of the software life cycle. These decisions have great repercussions in the evolution of a system. In addition, when changes are necessary it often happens that the structural decisions adopted do not accommodate the change. Software architecture defines the major computational elements of a system as a means to address these architectural-level decisions.
