Event-driven process chain

An event-driven process chain is like a flowchart that shows how things happen in a process. Let's say you want to make a peanut butter and jelly sandwich. First, you would need to gather all the ingredients, such as bread, peanut butter, and jelly.

Then, you would have to put the bread together and spread the peanut butter and jelly on it. After that, you can eat your peanut butter and jelly sandwich.

An event-driven process chain is like drawing these steps on a piece of paper. Each step is represented by a rectangle, and they are connected by arrows.

But what makes it "event-driven" is that each step is triggered by something happening. For example, you can only put the peanut butter and jelly on the bread after you have gathered all the ingredients. This is called an event trigger.

An event-driven process chain can help you understand how things happen in a process and make it easy to follow.
