【Abstract】 The characteristics of POSC data operation are analysed in the paper, and the conception of Epicentre view is put forward. The paper analyses the problem of Epicentre view to be resolved and the aim of Epcientre view, points out the technical key and the technical difficulties, gives a brief account of Epicentre view, that Epicentre view provides integration between OO-view with external mode and related\|view with internal mode, which will lay the foundation of its design and implement.更多还原
