Student status management is a very important part of university’s basic work. Its main work contains two parts: one is maintaining the data of CHSI(China Higher Education Student Information and Career Center), the other is maintaining the data of internal systems (such as the educational management system, student management systems, etc.). Errors occur frequently in the procedure of initial importing, updating, so the validation for student information is needed before. The procedure employs the independently developed Windows software, which used Java Swing technology. This software adopts the thoughts of mathematical set and relational databases. Its working principle is building a view between CHSI and internal systems with student’s ID. The use of this software makes the validation of student information simpler and student status management easier
