You work for a recycling company that provides customers with large compactor units to collect their recyclable materials. The compactor units are comprised of two separate components: a container to collect the recyclable materials and a separate component that compacts the recyclable materials to make them easier to transport.
These containers are expensive, and the components tend to break down frequently, requiring ongoing maintenance and repairs.
You need to easily track the containers that your company has at each client location and maintain a service history for each of the sub-components.
