According to the scientific development, standardized management, universities or colleges are exploring the construction of digital campus. However, in the pre-construction informationize process, the independent of one another. When a unified application platform will be constructed at a later stage, there have been a lot of heterogeneous data and heterogeneous databases. This paper analyzes the problems needing improvement and the matters deserving attention especially the heterogeneous distributed databases.
