How it can be learned from these massive, outdated data for student management to assist decision-making becomes a very realistic subject. This paper takes the transaction data of campus card as the research object, and uses the comprehensive application of data warehouse, online analysis and processing, data mining and so on to excavate useful information hidden in campus card transaction. This paper first introduces the data warehouse, data mining technology, then it analyzes the consumption behavior of the student canteen, and then builds the data warehouse model according to the analysis of the theme, sets the dimension, selects the granularity, from the card business system we extract the appropriate data for cleaning, conversion and loading into the data warehouse, finally, through the data mining technology we analyze the data to find the rules for the school decision-makers and provide the decision support for the relevant management departments.
