Abstract: A method of ordering a plurality of messages received from a sender to be sent to a receiver in a sequence based on the dependency of one message on one or more other messages, the method comprising the steps of: receiving one or more messages from a stream of messages and storing them in a database; identifying a characteristic (P-Key-Order) of each message which is common to a group of messages; identifying a message dependency for the messages in the group of messages from a parameter of the message; reviewing a particular stored message in the database to determine if the stored message can be sent by; determining whether the stored message is dependent on a previous message and determining a status of the previous message; updating the status of the stored message based on the status of the previous message; sending the stored message after acknowledgement that the previous message has been sent.
