Abstract: Based on the analysis of the main problems of data sharing and exchanging technology in the development of university informationization and the construction of digital campus and smart campus, the overall structure of DAAS platform for data sharing and exchanging is proposed, combining the actual business needs of teaching, research and management in the process of current university informationization.The platform is centering on distributed data services, distributed data exchanging and centralized task scheduling.Andthen, the key technologies of the platform are discussed in detail.Through the platform, the problem of rapid load pressure and low service efficiency caused by centralized data sharing and exchanging in universities can be better solved.
