Entity Services

In just about every enterprise, there will be business model documents that define the organization’s relevant business entities. Examples of business entities include customer, employee, invoice, and claim.

The entity service model represents a business-centric service that bases its functional boundary and context on one or more related business entities. It is considered a highly reusable service because it is agnostic to most parent business processes. As a result, a single entity service can be leveraged to automate multiple parent business processes.

Entity services are also known as entity-centric business services or business entity services.

The figure on the right shows an example of an entity service. Several of its capabilities are reminiscent of traditional CRUD (create, read, update, delete) methods.
