Electronic Commerce Modeling Language (ECML) is a way of talking to computers so they know how to buy and sell things on the internet. Think of it like playing with toy cars - you need to know how to talk to someone else who wants to play too so you can agree on how the game will work.
When you buy things online, you put things in a virtual basket or cart, and then you "check out" and pay for them. That's the fun part for you as a shopper, but behind the scenes there's a lot of work being done by computers to make sure that your purchases go smoothly. ECML is a set of rules that computers follow to talk to each other and agree on how the buying and selling process will work.
These rules cover things like what types of payment methods are accepted, what information needs to be shared to complete a transaction, and how to handle things like refunds or cancellations. By following these rules, online stores and their customers can work together to make purchases happen quickly and smoothly.
One important thing to remember is that ECML isn't just one thing that you can point to - it's more like a whole set of guidelines that helps different computer systems work together. By using ECML, everyone can work together to buy and sell things online in a way that's safe and secure for everyone involved.
