Research And Application Of Data Mining Technology In The Campus Smart Card System

Under the condition that Info-tech is increasingly developed, many colleges anduniversities are establishing and completing the digital campus. As an essential componentof the digital campus, all-in-card system plays a very important role in various works. Itproduces quauntities of data during the operation without any function of analysis. Thus, itcomes to be a very realistic subject on how to obtain information that is helpful to decisionmaking among school admin authorities from massive and useless data.Taking transactions of all-in-card as the investiagted objective, this report digs up theuseful information concealed in it by combining data warehouse, on-line analyticalprocessing and digital excavation technology. The report firstly introduces the fundamentalprinciple of data warehouse, OLAP and digital excavation technology, and sets up threethemes of student consumption, hot water consumption and commercial sales respectivelyon the basis of comprehension to the system function and data. Then, according to theanyalised themes, a data warehouse model would be constructed as well as dimension andgranularity to clean, convert and be loaded for the relevant data extracted from all-in-cardsystem. And the rules is uncovered by OLAP and digital excavation technology analysis.This reports illustrates some ignored information that is contained in cash-flow ofall-in-card system, which is initiative to decision-making. And it will lay a solid fundationfor decision support system for construction of Institue in the future.
