Method of performing data mediation, and an associated computer program product, data mediation device and information system

A data mediation device in a data communication network capable of conveying data messages representing requests for data services, the requests being expressed in a first format for data access, said first format defining a plurality of message parameters, and the data messages being encoded into a second format for transport in the data communication network, the data mediation device comprising:

• at least one processor;
• and
• at least one memory coupled to the at least one processor and comprising computer readable program instructions embodied therein that, when executed by the at least one processor, causes the at least one processor to perform operations comprising:
• receiving an incoming data stream from said data communication network and analyzing the incoming data stream to determine an inbound second-format binary message in said incoming data stream;
• processing a part of the inbound second-format binary message by parsing message parameters, the message parameters comprising a selected subset including less than an entirety of said plurality of message parameters, and generating a run time data structure to represent the parsed message parameters in said selected subset such that the run-time data structure represents less than the entirety of said plurality of message parameters defined by said first format for data access, wherein the inbound second-format binary message is stored in memory and kept therein after generating the run-time data structure;
• processing the generated run-time data structure by applying a data mediation logic defining actions to be taken upon incoming data messages including modifying any of the message parameters in said selected subset and/or adding new message parameters based on the parsed message parameters;
• building an outbound second-format binary message from the inbound second-format binary message and the generated run-time data structure by accessing the inbound second-format binary message as stored in memory and reusing at least one same sequence taken therefrom encoded in the second format for transport in the outbound second-format binary message, responsive to processing the generated run-time data structure;
• and
• sending said outbound second-format binary message in an outgoing data stream on said data communication network.
