摘要

Variable-length objects are urgently required in recent information-intensive and internet-intensive application domains, such as office information system, multimedia document system, and Web software. Furthermore, in these fields, the schema tends to be changed. This paper proposes one approach to integrating a variable-length object concept into C++-based object-oriented database systems. In addition, schema evolution, based on the variable-length object, is proposed. These features are introduced while keeping C++ specification, without affecting applications, and without performance degradation by changing schema. These features have been implemented for an NEC's commercial object-oriented database management system, called PERCIO.
