Abstract

Traditional query languages applicable to and used with the databases like SQL databases are not very suitable for construction of queries for the hyperlinked documents. The query language should have certain unique grammar to facilitate appropriate queries.

Query Language for Hyperlink Networks

      Traditional query languages applicable to and used with the
databases like SQL databases are not very suitable for construction
of queries for the hyperlinked documents.  The query language should
have certain unique grammar to facilitate appropriate queries.

      This invention proposes a language more suitable for the
information base linked by the hyperlinks.  The invention identifies
appropriate verbs and objects of the queries.

      Existing query languages like SQL are really designed for
tabular information.  SQL like languages are heavily dependent on the
index structures.  It relies heavily on the preconceived rows and
columns.  The topology of the information organization and
relationships in a hyperdocument is a graph which is a radically
different organization.

      Just to point out few key differences:

1.  Each piece of information is potentially linked ("related") to
    several other pieces of information.
2.  Each piece of information can be radically different from the
    rest of the information.  The difference can stem not only from
    format but also from the content of information.

      SQL like languages which are designed to query a data base of
information is fundamentally designed around a table and keys
structure.  Such a language can be very unwieldy and almost
impossible to use with hyperlinked information database since such an
information base can contain almost a limitless number and types of
relationships.

      The traditional 'flat files' and tables based information
organization is completely contrary to the organization of the
information in a hyperlinked multimedia docum...
