For dynamic clustering of objects, a data accessing model of online object-oriented databases is proposed in this paper. Dynamic clustering for object-oriented databases is an important issue in database management systems. Most of the previous paper has focused on the schemes of the dynamic clustering to optimal disk rearrangement and not many works have been done on the behavior of the data requested pattern. For the data accessing sequence to consolidate and advance the state of research in object clustering problem, a statistical model of data accessing behavior is proposed.
