Querying structured documents with hypertext links using OODBMS
1994
Proceedings of the 1994 ACM European conference on Hypermedia technology - ECHT '94
Preserved Fulltext
Querying in hypertext has been a requirement since [19] and has already been elaborated in many hypertext systems [11,7,4,21], but has not yet been used for hypertext systems superimposed on an underlying ...
Hierarchical logical structure and hypertext links are complementary and can be combined to build more powerful document management systems [28, 25,24, 13]. ...
