Automated technique for code generation of datastream mappings

A method of automatically generating datastream mappings, comprising:

• receiving a transaction in a first protocol;
• determining which transaction was received from a protocol definition for the first protocol;
• determining, from mapping data for converting the transaction from the first protocol to a second protocol, each transaction required to perform the received transaction in the second protocol;
• formulating a set of equivalent transactions by allocating all required fields for each transaction required to perform the received transaction in the second protocol;
• and
• determining, from the mapping data, how to map each field within the received transaction to one or more corresponding fields in a transaction in the second protocol.

A system for automatically generating datastream mappings, comprising:

• a protocol definition for a first protocol;
• a protocol definition for a second protocol;
• mapping data defining each mapping or procedure required to convert any element in the first protocol to one or more corresponding elements in the second protocol;
• and
• a code generator selecting an element in one of the first or second protocols and generating executable code or data structures required for conversion of the selected element from the one protocol to an other of the first or second protocols.

A system for automatically generating datastream mappings, comprising:

• a transaction in a first protocol;
• and
• a converter:
• determining which transaction was received from a protocol definition for the first protocol;
• determining, from mapping data for converting the transaction from the first protocol to a second protocol, each transaction required to perform the received transaction in the second protocol;
• formulating a set of equivalent transactions by allocating all required fields for each transaction required to perform the received transaction in the second protocol;
• and
• determining, from the mapping data, how to map each field within the received transaction to one or more corresponding fields in a transaction in the second protocol.

• instructions for retrieving a protocol definition for a first protocol;
• instructions for retrieving a protocol definition for a second protocol;
• instructions for retrieving mapping data defining each mapping or procedure required to convert any element in the first protocol to one or more corresponding elements in the second protocol;
• instructions for selecting an element in one of the first or second protocols;
• and
• instructions for generating executable code or data structures required for conversion of the selected element from the one protocol to an other of the first or second protocols.
