InterSect: A General Purpose Hypertext System Based on an Object Oriented Database
Most complicated documentation maintenance environments require sophisticated computer support systems for maintaining relationships between document types and document instances. Unfortunately, existing approaches are not sufficient to achieve this aim. Hypertext technology gives us the possibility to easily browse document contents but it lacks a mechanism for declaring the overall structure of the document and its relationships. Database management systems can model complex real world situations, but do not have “the single coherent interface to the database which is the hallmark of hypertext”. In this paper, we propose a general hypertext-based documentation support system, InterSect, which uses an object oriented database as an information repository to support both the definition and manipulation of complex document structures. This prototype provides both hypertext and database views of documents, together with a versioning mechanism driven by a user defined schema for the overall document structure.
