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.

A diagram hung there instead,
More women born than men.””
