You addressed the following problem:

Government service departments are deeply burdened by the amount of data that they hold and process. Interview someone from a service department and draft a short essay. Example service departments that must sift through vast amounts of data are those that deal with, for example, missing persons, child protective services, DMV, and tracking of persons on probation following a crime. You should include, but are not limited to topics such as:

• What is the department (or person’s) job?

• What kind of data do they collect and analyze?

• What kind of analyses do they do on the data?

• How much information do they collect and from whom, and what programs do they use?

In this exercise, utilize the information you gathered from your interview and draft a complete DFD of the existing information system for that department. You may need to go back and reinterview your contact or get forms, reports, and so on, so that you have a complete picture of the flow of data.
