Types of workflow in the WF

Question

State the types of workflow in the WF?

Answer 1

In WF 4.0, following two types of workflows are to be used:

a) Flowchart workflows – It helps you for creation of the workflows using common flowchart elements. In WF, Flowchart activity is normally used for implementing a non-sequential workflow, and rarely does it implement the sequential workflows if FlowDecision nodes are not to be used. Flowchart activity comprises of collection of flow nodes that is inherited from the FlowNode class.

Following types of elements or nodes are part of the flowchart:

a) FlowDecision – It provides implementation on the basis of a Boolean condition. It is same to the If construct.

b) FlowStep – It implements activities of a flowchart in the sequence.

c) FlowSwitch – It provides implementation on the basis of an exclusive switch. It is similar to Switch construct.

d) Procedural workflows – It helps the creation of workflows by using the basic and sequential execution standards. In WF, procedural workflows use the flow control constructs, like Switch, While, ForEach, and If, to implement the activities.  All these flow control constructs are same as those found in the procedural languages. Procedural workflows also consists of other flow control activities, like Sequence and Flowchart.
