Research Reason
Growth of Industry and Multimedia gt Increasing
demand of database System
Using obvious queries gt hard to use database
except the DB expert
so, need fuzzy queries and natural language
process
Fuzzy
SQL
Developed, Developing FSQL and FSQL System that
is to process fuzzy queries and some natural
language in a Relational DB
