A Data Structure Diagram (DSD) is a data model used to describe conceptual data models by providing graphical notations which document entities and their relationships, and the constraints that binds them.
The basic graphic elements of DSDs are boxes, representing entities, and arrows, representing relationships. Data structure diagrams are most useful for documenting complex data entities.

“The question is still asked of women: “How do you propose to answer the need for child care?” That is an obvious attempt to structure conflict in the old terms. The questions are rather: “If we as a human community want children, how does the total society propose to provide for them?””
—Jean Baker Miller (20th century)
“If a fish is the movement of water embodied, given shape, then cat is a diagram and pattern of subtle air.”
