10. The method of claim 9 , wherein the exoskeletal cast constrains the codes permitted within a segment to ensure semantic integrity.
9. A computer-based method of recording medical transactions through de novo composition and construction of medical transaction codes: including the steps of: inputting medical transactions in a semiotic form one, the semiotic form one input being a free form-type, abbreviation-oriented natural language textual input, parsing said semiotic form one input and converting it into coded medical transactions in a semiotic form two output, the transaction codes composed and constructed de novo, the semiotic form two output embodying high level machine-parseable computer language statements comprehensible to a high certainty level by human users, causing a user display to display system reflection in the form of coded medical transactions in said semiotic form two and system-rated confidence levels representing the match between a code and correspondence with perceived user intent, receiving user selection input for verifying a selected coded medical transaction, converting a semiotic form two input into a semiotic form three transaction by mapping the selected coded transaction into data row in a relational database to render the transaction data amenable to structured query language processing, and including extracting a transaction in semiotic form two as an exoskeletal cast independent of the data content held within.
