QUERY FORM INTERFACE

QUERY FORM

     1.   Each  query form corresponds to an SQL template.      
     2.  A query form is defined as a 4 tuple which include  
                             
                    i). Attributes  for projection.
                   ii). Set of " n" relations in query.
                   iii).Conjunction of expression for selection(condition) on relation.
                   iv).Join function to generate a conjunction of expressions for  joining relations.
    3. Query forms allow user to fill parameters to generate different queries.

            This paper focus on the projection and selection components of query form.


QUERY RESULT    

   To decide whether a query form is desired or not , a user does not have time to go over every data        instances in query result. We know that many db queries output a huge amount of data instances.

   To avoid this "MANY ANSWER PROBLEM" here output a compressed result table to show high
   level view of query result.

   Each instances in compressed table shows the cluster of actual data instance.

   Many one-pass clustering algorithm for generating the compressed view.

   In this paper, use the incremental clustering algorithm for achieving efficiency.
