Definitionv1DF-250
System structure
the pattern that emerges when you see all the relationships between components simultaneously, which determines system behavior rather than individual components or actors
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'system structure' by identifying its genus (pattern emerging from relationships) and differentia (simultaneous viewing of all relationships). It distinguishes structure from mere components or actors, and explains its causal relationship to behavior. The definition is consistent with the lesson's central thesis that structure is invisible until all relationships are mapped together.
