   1. The note type concept ID is not very useful and should be replaced with a more standardized terminology such as LOINC ontology
   2. Replace the current single element with 5 elements (pls see presentation for details)
   3. Extend the note source value field to 255 varchar
   4. In terms of the type of service, LOINC ontology is very complicated, A flat architecture would be better for the current purpose. Comparison with another institution should be carried out.
