An Application Software Architecture Based on C2 and Three Levels Style

A mix structure with C2 and three levels style is proposed in this paper.In this new architecture,it bases business logic on C2-style,blends three levels C/S model,and the usage of the structure is introducted by the design and implementation of Robust-PID parameter autocontrol system.As is proved by practice,the structure has many advantages such as explicit structure,easy to modify,better portability and big reusable granularity.
