Fault Tolerant Design Features

An important consideration when developing life-critical applications is to include design elements that mitigate the effects of run time errors. One way to do this is by using fault-containment regions, where critical components are isolated from other parts of the system to prevent errors in one area from propagating to another, otherwise unfailed portion of the system. Another way is to include sanity checks on process inputs and outputs, where pre-conditions and post-conditions are checked and enforced at runtime.

To this end, Part 2 requires you to store the base-related information of Part 1 in a Friendly site data dictionary, and the target-related information of Part 1 in an Enemy site data dictionary. That way when we are destroying enemy targets, we do not instead accidentally blow up little Billy's house, much less Dr.  Samet's.

Because Dr. Hugue's research area is dependability, you will have the unenviable pleasure of implementing fault isolation and transformation strategies that will decrease the probability that user errors can result unexpected and unwanted civilian and non-combatant casualties.
