Answer to Question 1

A rectangle with rounded corners represents a process. A process is the work or actions performed on data. The data store represents data at rest, and is represented by a rectangle with the right vertical line missing. A data flow represents data in motion, and is represented by an arrow. A source/sink is the origin or destination of data. Sources and sinks are identified by square symbols. Computing a grade point average is an example of a process. A file folder containing orders is an example of a data store. An enrollment form being routed through the enrollment center is representative of a data flow. A student enrolling in school is representative of a source/sink.
