Entity application component: An entity component is frequently derived from business entities, and is responsible for managing the access to the entity, and its integrity.

Interaction application component: Represents the top level components that manage the interaction with elements outside the IS. In most cases, it is a GUI component, such as here a web interface.

Process application component: A process application component is responsible for a business process execution. It orchestrates the tasks of the process.

Utility component: Represents an application component that is frequently reused, and most of the cases bought off the shelf.

Database application component: Represents a repository. In pure SOA architecture, these elements should not appear. However, for legacy analysis or technology architecture, modeling repositories or repository deployment can be useful.

System federation: A system federation is the coarser-grained application component. It assembles systems to federate them, such as in the example of cooperation between different information systems between different companies.

Application: This application component corresponds to legacy applications, off the shelf products, or can be an assembly of application components.

Business Entity: Describes the semantics of the entities in the business, independently of any IS consideration (e.g. storage, technology, etc).

Data flow: Expresses that data (for example business entity) is input or output from a dynamic entity.
