Data query based on object-oriented data model
Zhang Lian · 2000
Because object\|oriented data model can express abundant and complicated semantic, it is difficult to inquire object\|oriented data model. This paper analyses query method of POSC Epicentre data model. It concludes that it can build source entity\|kernel entity single direction multi\|reference query method or it can build source entity\|kernel entity explicit and inverse direction reference method. By means of these two methods, we can break down the above mentioned methods.
