2. Problem #1
(i) Select either a military or healthcare application and specify various policies (i.e. security or privacy constraints) to illustrate the inference or privacy problems
(ii) Show how a system may process the policies (i.e. constraints) in Part (i) during query, update and database design operation.

3. Problem #2
(i) Describe a military and healthcare example with policies (security or privacy) and show how conceptual structures/models may be used to represent the applications
(ii) Show how a system could reason with the policies and the conceptual structures of (i) to determine security or privacy violations through inference.
