Data base and its implantation through various means, always demand the security of data which is stored in it. From view point of security from earlier days the DBA stores the data at different levels and level is available to the concerned person only. The data with the highest level of security is also termed as persistence data. Some authors also consider the term persistence as proper means of storage and retrieval of data from the storage devices. During this storage and retrieval the overlapping of code for verification of user make it implementable as cross cutting concerns.
