内容記述 | Rapid advance in computer network technology has changed the style of computer utilization. Distributed computing resources over world-wide computer networks are available from our local computers. They include powerful computers and a variety of information sources. This change is raising more advanced requirements. Integration of distributed information sources is one of such requirements. In addition to conventional databases, structured documents have been widely used, and have increasing significance in such advanced applications as digital libraries, electronic commerce, World Wide Web, and hyper-media descriptions. Thus, integration of structured documents and conventional databases is one of the most important issues today. However, structured documents are different from conventional databases in their self-descriptive nature and various structural constructors. And the difference makes the integration much difficult. This dissertation proposes an information integration system for not only conventional databases but also information sources containing structured documents. In particular, structured document repositories, Web, and relational databases are chosen as target information sources. Data models for integration of structured documents and relational databases are proposed. They are hybrid data models based on nested relational structures and an abstract data type for structured documents, and allow symmetric transformation between relational structures and structured documents. Utilization of such hybrid and symmetric data models is the most distinguishing point of the information integration system studied in this dissertation. A query processing and optimization scheme for the integration system which utilizes the hybrid and symmetric data models is studied. The integration system is supposed to consist of software modules which communicate with each other and distributed information sources. ・・・ |
