The method to choose architectural approaches in the software architecture design phase

To design a software system, many architecture styles have to be combined to construct the overall architecture of the system. What to choose among various architecture styles or architectural approaches depends on the fact of what kind of functional or non-functional quality requirements the system should satisfy. In this study, the satisfaction level of system requirements is evaluated through estimation about technical parts of architectural approach, so designers can use the information when they choose architectural approaches in the designing process.
