Campus card is used to record learning, living and entertainment data of students during school learning period. It contains numerous valuable information of student daily behavior. The effective integration of campus card data is the basis for further mining and analyzing of student behavior. This paper presents the design and implementation of a data integration and analysis system for campus card. This system is analyzed and designed by Unified Modeling Language (UML) and implemented by Java. The main input involves the records of consumption, entrance guard, library and other types of related data. This system can used to integrate common types of source data and provide several kinds of statistical charts and tables to illustrate the analysis results. Moreover, the system supports to add new functions in terms of plugins.
