Sorry that I am still very new to this OMOP CDM
a) Can I know what is the workflows like? say we have our input raw data (medical), how do we know which domain(s) would that raw data would need to be mapped to based on OMOP CDM? would there be cases where the raw data needs to be mapped to more than one domain?
b) How do the actual implementation of the mapping like? Is there some software tool for the implementation of the mapping?
c) How would the output which is mapped to OMOP CDM like? Is it some kind of database or just .CSV files?
d) Do you have some simple examples to illustrate the workflow, with some sample raw data?
