Peter Chen

Chen's original method is the basis for many writings on ERDs. While the traditional aspects of entities and relationships are represented as boxes and lines (respectively), there are a number of unique attributes to his present method:

  1. The cloud symbol represents aggregations of smaller ER diagrams, in the context of a logical design (as opposed to a physical design).
  2. The double-box stands for a weak entity, which is dependent on its parent entity.
  3. A diamond symbol represents a type of relationship.
  4. Relationship adornments are added adjacent to the lines to indicate connectivity (I, M, N) and cardinality.
  5. The data-structure diagram (an alternate form of the ERD) uses arrows to show I:M relationships.
  6. Circles symbolizes the attributes of an entity, although Visio labels this icon as value.
  7. A human figure represents a user icon.
