Entity types
An entity represents some thing (person, place, event, concept) about which the system records information. Entities correspond to tables in the physical data model.
A single entity on a logical model can become a single table on a physical model, or it can be part of one table or it can be divided into many tables.
Logical data models support independent, weak, associative, and super-and sub-entities. The entity symbol is automatically transformed to reflect the appropriate dependencies.
