IDOC is very similar to XML. They share the same purposes: data exchange and automation in computer systems. But their syntax is different, there are different types of IDOCs transactions. It is used for asynchronous transactions which means that they exist as self-contained text files that can be transmitted to the requesting workstation without connecting to the central database.
