The FairCom DB API function SetDataFilter() can be used to establish a temporary, user-specific, filter for data record access (see “Data Filters and Conditional Indexes” in the FairCom DB Programmer’s Reference Guide). Consider the case of requiring a customized security audit trail. Individual record reads and writes can be monitored and logged with these permanent filters in place. An application could also use this feature to restrict a user’s ability to read and/or write records based on the row from the table of interest, thereby enabling a row level security mechanism. The username, table, and operation attempted, including the record image, are all data available to your application. SetDataFilter now supports establishing a new type of permanent system-wide filter.
