Title
Database support for very large hypertexts
Source
Electronic publishing review. 3(1990) no.3, S.141-154
Year
1990
Abstract
Current hypertext systems have been widely and effectively used on relatively small data volumes. Explores the potential of database technology for aiding the implementation of hypertext systems holding very large amounts of complex data. Databases meet many requirements of the hypermedium: persistent data management, large volumes, data modelling, multi-level architecture with abstractions and views, metadata integrated with operational data, short-term transaction processing and high-level end-user languages for searching and updating data. Describes a system implementing the storage, retrieval and recall of trails through hypertext comprising textual complex objects (to illustrate the potential for the use of data bases). Discusses weaknesses in current database systems for handling the complex modelling required
