Semantic network
data
A graph consisting of nodes that represent physical or conceptual objects and arcs that describe the relationship between the nodes, resulting in something like a data flow diagram. Semantic nets are an effective way to represent data as they incorporate the inheritance mechanism that prevents duplication of data. That is, the meaning of a concept comes from its relationship to other concepts and the information is stored by interconnecting nodes with labelled arcs.
