A "transaction set" is the standard format used in the electronic transmission of a single document (e.g. freight bill) between computers. Each transaction set is composed of a series of segments. An individual segment consists of related data elements used to convey a logical grouping of information (e.g. a line on a freight bill). A data element is the smallest discrete piece of information that can be conveyed (e.g. the weight of a line item on a freight bill).
