A simple state has no substructure, just a set of transitions and possible entry and exit activities. A composite state is one that has been decomposed into regions, each of which contains one or more direct substates. Table 7-3 lists the various kinds of states.
|simple state||A state with no substructure|
|orthogonal state||A state that is divided into two or more regions. One direct substate from each region is concurrently active when the composite state is active.|
