Hypermedia systems are information support systems which consist of nodes containing text and multimedia informations, and links connecting nodes. It provides users with a natural information retrieval methods using browsing. But, there are many databases built on relational DBMS. The hypermedia browser may be a convenient user interface to navigate the existing relational database.
In this thesis, we propose a database retrieval method using navigation which was popularized in hypermedia. Our proposed retrieval method covers all forms of queries related with retrieval. It can be applied to relational database without the knowledge of schema and information provider's additional works.
