Dynamic Query Processing for Hidden Web Data Extraction

In this digital world every one seeks for the information on the internet. As the time passed every one placed their digital content on the web. On the web the website developers support to place the data in the relational databases. The databases from different organizations and agencies are available online and are accessible through web query interfaces. The web query interfaces act as the front door to access the information from these relational databases. But these web forms or web query interfaces need human intervention to submit the form data. So in order to make search engines capable of accessing the relational databases i.e. data behind query interfaces, the query generation should be done automatically. So in this paper we discuss the different form submission techniques to fetch the data from the databases and propose a novel technique “Dynamic Query Processing for Hidden Web Data Extraction”.
