Implementation... (continued)
Security Mediator Workstation accepts the customer query, logs it, and passes control to the Security Mediator Software (SMS)
SMS reads the security_rules table and calls many different modules (sub-routines) to validate the query (pre-query checks)
If okay, SMS executes the query (Embedded SQL calls)
Mediator Workstation gets results from the database and calls other SMS modules to perform the post-query checks
If all checks are passed, the Mediator Workstation logs and returns results; awaits another invocation
Result is accepted by customer and used or displayed
