Consider the following system description. An inter-active system is based on a number of computationally independent execution structures (groups of software and hardware) such as database, business logic, web interface, servers, routine services such as security, and connected by some communication media. The software components are loosely coupled. Individual software hardware components can be re-arranged, added or removed. The architecture must support specific operational requirements and resource usage. Which of the following two architectural styles is most appropriate for this system and discuss the reason for selecting this style. Pipe-and-Filter style Layered style Which non-functional requirements are achieved in this style and how? Why you did not choose the other style
