BPM 12c Gateways (Part 1 of 5): Exclusive Gateway by Antonis Antoniou

Oracle BPM provides us with various components to control the flow of a process such as gateways, timer events, errors, message events, send and receive tasks, loop markers and multi-instance markers.
In this five part series part I will be elaborating the gateway control flow components and how we can use them to define the flow of our process.
Gateways are very similar to a flowchart decision element. Using a gateway you can define the control points within your process by splitting and merging paths. At runtime a gateway will determine based on the control points defined at design time the path that a token will take through a process.
There are five gateway types; Exclusive Gateway (XOR), Inclusive Gateway (OR),  Parallel Gateway, Event Based Gateway and Complex Gateway.
Exclusive and Inclusive gateways consist of two outbound sequence flows; a default sequence flow representing the normal path between two objects and a conditional sequence flow to control the process flow based on the evaluation of an expression. Read the complete article here.
