Business process execution language, also known as BPEL, is like a set of instructions for computers to follow in order to complete specific tasks. It's like a map that tells the computer what to do step-by-step to get something done.
Imagine you wanted to make a sandwich. You would need to follow a specific set of instructions to make the sandwich. These instructions might look something like this:
1. Get two slices of bread.
2. Spread peanut butter on one slice of bread.
3. Spread jelly on the other slice of bread.
4. Put the two slices of bread together.
5. Cut the sandwich in half.
BPEL works in much the same way for businesses. It provides step-by-step instructions for how different software systems should interact with each other to complete a task. For example, it might be used to automate the process of creating a new customer account. The BPEL would tell the computer to check if the customer already exists, create a new record if the customer doesn't exist, and send an email confirmation to the customer.
Overall, BPEL is a tool that helps businesses automate their processes and save time and resources.
