ABSTRACT:
A method and system are provided for performing the recovery of deleted user data in a database datafile. The database datafile may be stored in data storage and may contain one or more flags or “deleted-data flags” indicating that the database datafile contains deleted user data. For recovering the deleted user data, the system receives at least one input indicative of the database datafile, ascertains one or more addresses of deleted user data that have corresponding deleted-data flags, and alters at least one reference in the database datafile that corresponds to the ascertained addresses. Additionally, the system may search the database datafile for the deleted-data flags.
