Question 2:

A military information system on a base overseas tracks personnel on the base. Each military member is tracked by
ID#, name, rank, and address. Each military member belongs to an organization on the base which has an organizational name, located in a building on the base and has a primary function (e.g. Communications Squadron).

Each of these organizations is also commanded by one of the military members .

In tracking command sponsorship each military member may have one or more dependents. Each dependent has an ID#, name, age, and sex.

Each organization on the base is involved working issues or projects which may be of interest to the base commander. These projects are tracked by a serial number and an origination date.

The information system you are designing will also track descriptions of the projects and their close-out dates.

Build an entity relationship model for the above scenario.

Show all attributes and ndicate all of your key attributes in red.
