Now a day´s digital forensic investigators are looking into the suspicious organizations and companies for detecting various frauds. It is very important to have a data which has the overall information of data of the company. As we know that the structure of company´s database is very complicated it is very difficult for the investigator to investigate in the particular company if he or she doesn´t know anything about the company´s database. Many companies built a covert database for various purposes. First is to keep their marketing process secret and other is to hide their financial transactions which can also be called as the fraud transactions.
