Appeal No. 1997-3581
Application No. 08/010,291
The claimed invention relates to a relational data base
system and method for creating execution procedures for
realizing a query to a defined view table in advance of the
actual input of the query by a user. Appellant asserts at
page 10 of the specification that, by predicting the structure
of a query to a view table and creating a corresponding
optimum execution procedure prior to actual user query input,
the overall response for a query to a data base is reduced.
Claim 1 is illustrative of the invention and reads as
follows:
1. A relational data base system having a function of view
resolution for analyzing a query sentence in an execution
procedure for a query from a user, using a content defined in
a view table for the query designating the view table,
converting a retrieval of the view table to that of an actual
table, and creating the execution procedure, the system
comprising:
early bind definition means for creating and updating by
an evaluation execution time a plurality of execution
procedures when the view table is defined and before a query
is inputted, to realize the query subsequently inputted to the
view table in accordance with a query structure to the view
table;
a definition information dictionary operatively connected
to the early bind definition means to store information;
execution procedure management means provided in the
definition information dictionary for storing said plurality
