In a video conference system, business management system is a core component of the entire business environment. Based on the demand of the complexity of the design of the system structure, operation mechanism and the business logic, this paper designs a new architecture of business management system. Analysis of the overall structure of this system and study of the design of business module in detail are also given. On the basis of analyzing business management system of video conference system, this paper puts forward the business management system as a system model based on the layered architecture and this model reduces the complexity of the system. Simulation results show that this scheme effectively improves the efficiency of business processing of business system.
