Analyzing multidimensional database, the paper puts forward multidimensional technology which may be used in discipline-oriented knowledge warehouse. The paper takes example for constructing a tridimensional data cube structure model of electronic journals database, and simply defines data cube model, analyzes various multidimensional operation action, like slice, dice, drill-down and roll-up, and pivot. The paper realizes physical memory of multidimensional database by many ways.
