1.1.6 Explosion structure
Each object, relationship or role in a graph can also be
linked to other graphs via explosion structure (Figure 1–6
). The explosion
structure allows to select one element from the graph and explode that to a new
graph. An object (or a relationship or a role) can have a different set of
explosions in each graph where it is used. Explosion always happens by first
selecting one object, unlike decomposition where several can be selected.
Explosion is often used between different graph types.

decomposition, explosion structures are also method dependent. An example of a
explosion graph can be found from most object-oriented methods, in which an
Object or Class in an Object Diagram can be further described in a State Diagram
by exploding it into a new graph.
