Much of the business world relies on the exchange of information between applications. This information is contained in messages that have a defined structure that is known and agreed by the sender and the receiver.
You can model a wide variety of message formats so that they can be understood by IBM® Integration Bus message flows.
When the message format is known, the broker can parse an incoming message bit stream and convert it into a logical message tree for manipulation by a message flow. After the message has been processed by the message flow, the broker converts the message tree back into a message bit stream. Conversion to and from a bit stream is performed by a parser. IBM Integration Bus supplies several parsers, each suited to a particular class of message formats called a domain.
