Versatile Querying Facilities for a Dynamic Object Clustering Model

The conceptual clustering model (CCM) that we have defined in [19] is an extension to current object-oriented models; it facilitates the modeling of dynamic, evolving, and/or ad hoc object clusters through a well-devised clustering mechanism that incorporates “roles”. To support general definition and access of clusters (and roles), associated query language facilities have been defined and are presented in detail in this paper. An experimental prototype of the CCM and its associated query language are being implemented on top of a persistent object storage manager.
