A Study on the Requirement-driven Adaptive Architecture of Information Systems
Guoxi Cui · 2008
The concepts and features of information systems architecture (ISA) are introduced and the importance of the ISA to the development of contemporary information systems is illustrated.The historical evolution and current states of the ISA research and development are summarized.A framework of proposed ISA:Requirement-driven Adaptive Architecture (RDAA) is described.The paper illustrates the features of multiple layered structure and the mapping principles between layers of RDAA and its adaptive mechanism of the combination of case-based and norm-based reasoning together with negotiation and coordination.The abilities of dealing with complex issues,adapting to the changing environment in RDAA and its properties of self-improvement and self-evolution are discussed.
