ABSTRACT:
A method for managing access to query results and, more particularly, for managing access by multiple users to persistently stored query results, whereby at least some of the users may have different access rights. One embodiment provides a method of managing access to a query result obtained upon execution of a query against one or more databases. The method comprises creating security information configured for restricting access to the query result, wherein the query result comprises a dataset obtained from one or more database in response to execution of a query against the one or more databases. The security information is associated with the query result. Access to some or all of the query result is granted to a requesting entity on the basis of the security information and an attribute of the requesting entity.
