Abstract: A large number of web data receptacles are hidden behind restrictive web interfaces, making it an important challenge to enable data analytics over these hidden web databases. This module is used to enabling the aggregate queries over a hidden database with checkbox interface by issuing a small number of queries (sampling) through its web interface. Then I have examined that this approach will be handled in both synthetic and real datasets demonstrate the accuracy and efficiency of the algorithms. Before that in this paper I have done a survey on some papers about the concept what they processed about the data analytics over hidden databases with checkbox interfaces.
