Business service/information diagrams
The business service/information diagram shows the information needed to support one or more business services. The business service/information diagram shows what data is consumed or produced by a business service and may also show the source of information. The business service/information diagram shows an initial representation of the information present within the architecture and therefore forms a basis for elaboration and refinement within phase C (data architecture).
This diagram presents the links between business services and business entities.
Three business services are based on four business entities
Business Entity: Describes the semantics of the entities in the business, independently of any IS consideration (e.g. storage, technology, etc.).
Business service: Represents a service provided by the business, which may then be realized by one or more IS services.
