A Transaction is a specialized type of subprocess. It allows describing what happens
if a whole set of activities is cancelled or
interrupted by an error.
Event Sub-Processes allow to handle an
event within the context of a given subprocess or process (either by interrupting
the process or running in parallelto it). They
are not part of a normal process flow, as
they start only when their associated Start
Event is triggered.

by a web service)

AnEvent is something that “happens” during the course of a
process. Events affect the flow of the process and usually
have a cause or an impact.
A Start Event indicates place where a process starts (e.g.
after receiving message, when condition is met, or at a
scheduled time).
An Intermediate Event happens between start and end of a
process. It may be part of a process flow (either throwing orcatching triggers such as Message) or represent
exception/compensation handling (when placed on the
Task/Sub-Process boundary).
An End Event indicates a process end. It may show e.g. that
a certain process path ends with an error or sends a signal
for other processes.

The new types of Events in the BPMN 2.0 are the types
Escalation andParallel Multiple as well as the whole
categories Event Sub-Process (Interrupting and NonInterrupting) and Boundary Non-Interrupting.

There are also markers that indicate characteristics of Activities:

A Choreography Task is an atomic Activity in a
choreography process. It represents an interactionbetween two Participants

The Choreography Diagram defines a sequence of interactions between Participants.

Sequence Flow –
defines the execution order
of activities.

A Sub-Choreography is an atomic Activity in a
choreography process. It represents an Interaction
between two Participants

ACall Choreography identifies a point in the process
where a Global Choreography or a Global
Choreography Task is used.

Conversation Diagram

Customer

The Conversation Diagram shows logical relation of message exchanges. In general, it is a simplified
version of Collaboration, but conversation diagrams do maintain all the features of a Collaboration. In
particular, processes can appearwithin the Participants (Pools) of conversation diagrams, to show how
Conversations and Activities are related.

A Conversation represents a set of Message
Flows grouped together.

The Business Process Diagram describes a Process i.e. a sequence or flow of activities in an organization
with the objective of carrying out work. Processes can be defined at any level from enterprise -wide processes
