A System for Oracle Users and Privileges with Automatic Expiry Dates

Tired of tracking down all the users in the database to deactivate them when they cease to exist, or change roles, or fulfill their temporary need to the database? Or, tracking down privileges you granted to existing users at the end of their requested period? The solution is to think out of the box - developing a system that allows you to create a database user account with an expiration date. This fire-and-forget method allows you to create users with the assurance that they will be expired (locked or dropped) at the expiration date automatically, without your intervention. Interested? Read on how I developed such a system--along with source code for you to try.
