These techniques are mainly classified into two categories: time-stamp method and version method. These methods limit the representation/manipulation capabilities because the change of class membership for an object is not well specified and the transitional states must be related mutually along the system-defined time axis. In this paper, we propose a method, which is basically derived from the object-oriented paradigm, for modeling time-varying characteristics of entities so as to be free from the above two limitations in the traditional methods. We introduce two representation media: core and surface. The core represents invariant features of entity, while the surface denotes variant features of entity. A snapshot of an entity is represented as an aspect, which is a database instance composed of the core and surfaces.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/6929"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "IEEE"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1109/CMPSAC.1996.544603", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright \u00a9 1996 IEEE.
