Entities and their relationships

In a Data Model, entities describe an object, such as a person or an item, by grouping a set of related fields. Each entity becomes a table in the database. Products, accounts, and transactions are examples of potential entities in a Data Model.

The connections between entities in a data model are called relationships. Relationships reflect business rules. Relationships between entities can be one-to-one, one-to-many, or many-to-many.
