Database Readings

  • Entity-Relationship Modeling

    - sections 1 through 3.12; especially the discussions of entities and entity types in section 2 and the discussions of relationships, cardinality and existence (which we will refer to as optionality)

  • Entities, Attributes, Relationships, etc.

    - follow the links or scroll down to read the Basics, Entities, Attribute, Keys, Relationships, Cardinality and Optionality sections

  • Crow's Foot Notation Info

    - from the Univ. of Regina, Canada; *note* we don't use the 'double line' notation that is shown in this link for 1:1 relationships and we denote primary keys by underlining them and foreign keys with an 'FK' after them
