During its transactions, HM uses entities and entity types to define and manipulate data. Database designers create entities, relationships, entity and relationship types, and profiles in the Hierarchies tool before working in the Hierarchy Manager tool.

An entity is any object, person, organization, place or thing that has meaning and can be acted upon in your database. Entities are described by a particular entity type that makes them easy to identify. Entities and entity types have a one-to-many relationship. For example, an entity called Party could have an Entity Type called Person and an Entity Type called Organization.

The following table lists some entities and entity types.
