| Abstract(in English) | Integration of heterogeneous information resources has been one of the most important issues in recent advanced application environments. In addition to conventional databases, structured documents have been recognized as important information resources recently. In this paper, we present a data model named NR/SD+, a revised version of NR/SD model we developed as a basic data modeling framework for the seamless integration of structured documents and relational databases. NR/SD+ (and NR/SD model) combines an abstract data type named the structured document type and the nested relational structures, and features operators named converters to dynamically convert structured documents into nested relational structures and vice versa. Features of NR/SD+ include its flexibility to cope with various structural constructs which occur in SGML-compliant documents, and capability of direct extraction and manipulation of text elements which appear inside the document hierarchy. These features are achieved by dynamic creation of references to structured document fragments. |
