Abstract: In order to bridge the "Information isolated island" in the enterprise information construction, it need to establish the subject database to realize the information sharing and the efficient communication between different departments. This paper introduces mathematical formulas in the plan of subject database and presents the algorithm based on entity affinity, makes the establishment of subject database more rigorous and standard. Moreover, it can be a guide for continuous correlated research and directs the transformation and reconstruction of the enterprise’s data environment.

Key words: information isolated island, data environment, entity affinity, subject database
