For each of the following cases,

Develop a DFD as indicated

Do not make any assumptions.

Identify all missing information (do not limit yourself only to the infinite sinks and sources, read-only and write-only data stores, and the miracles, black holes and grey holes).

Make sure you use correct DFD syntax including data store and external entity duplications, process and data store numbering, and process, external entity, data flow and data store labelling.

Open Road Insurance System: The purpose of the OPEN ROAD INSURANCE SYSTEM is to provide automotive insurance to car owners. Initially, customers are required to fill out an insurance application. A drivers traffic record is requested from the local police department. A vehicle title and registration are also requested from the bureau of motor vehicles. Proposed policies are sent in by various insurance companies that will underwrite those policies based on a quoted fee. The agent determines the best policy for the type and level of coverage desired and gives the customer a copy of the insurance policy proposal and quote. If the customer accepts, he or she pays the initial premium and is issued both the policy and a state-required insurance coverage statement (a card to be carried at all times when driving a vehicle). The customer information is now stored. Periodically, a premium notice is generated, which- along with policy coverage changes- is sent to the customer, who responds by sending in a premium, after which new insurance coverage statements are issued. Represent the system in the above narrative by first a system level DFD and then a hierarchy of DFDs.
