A process flow is a set of activities arranged in a sequence to perform a specific task. Combining various activities, that is, Source, Target, Schema, Mapping, or Transformer creates a process flow.  A Process Engine controls the execution of a process by starting the execution of process flow instances and all the activities present in a process flow. When the process flow is executed, data from the source is converted to the intermediate form and dispatched to the target.

Understanding Web Process Designer

Web Process Designer

allows you to design business processes and business rules. The Business Process Modeling Notation (BPMN) standard is used to graphically depict business processes. The Process Designer is easy to use and enables both technical and non-technical users to design processes.

Element	Description	Notation
Activity	An activity is a work that is performed within a business process. The rectangle image displayed in the next column is used to depict an activity in a process flow.	Image Added  Activity
Gateways	A Gateway is used to control the divergence and convergence of a sequence flow. Thus, it determines branching, forking, merging, and joining of paths.	Image Added  Gateway
Start Event	A start event starts the execution of a process.	Image Added
Error Intermediate Event	Error Intermediate Event is used to redirect Process Flow execution to an alternate path in case of failure of any activity during process flow execution.	Image Added
End Event	An end event, ends the flow of a process flow.	Image Added
Data Object	Data Objects do not have any direct effect on the sequence flow of the process. They are used to provide additional information for the reader of the process flow diagram. You can add any amount of information in this element.	Image Added Data Object
Hand Tool	A Hand tool is used to move all the activities in the Canvas area.	Image Added
Lasso Tool	Lasso tool helps to select multiple BPMN elements from the Canvas Area and move them to another location.	Image Added
Create/Remove Space Tool	Space tool is used to increase the space between the two BPMN elements.	Image Added
Global Connect Tool	Global Connect Tool used to connect the BPMN elements in Canvas area and it shows the order that activities are performed in a business process.	Image Added

The Repository View lists the Connect Server objects, such as Activities, Actions, and Process Flows.

• Activities: All the activities that can be used to create a process flow are listed in the Activities tab. You can expand the service to select the activity and drag it to canvas area to create a Process Flow.
• Actions: Actions enable necessary control over a process flow. You can select the Action and drag it to Canvas area.
• Process Flows: It displays the existing Process flow. Double-click the process flow to open in on Canvas area.

The Canvas is the area where a process flow is drawn. BPMN specification and Connect Server activities are dragged onto the Canvas and arranged in a sequence in order to create a process flow. The Canvas can also be resized if an activity is dragged beyond the default size.

You can also perform these activities in the Canvas area:

• Click Image Added icon to view canvas area in full screen.
• Click Image Addedicon to view Mini Map of the process flow.
• Click Image Added icon to zoom In.
• Click Image Added icon to zoom out.
• Click Image Addedicon to reset zoom.
