Trouble with CIRCE/WebAPI in OLYMPUS

Thanks, @Chris_Knoll

and I have another wondering.
I inserted values into ‘source’ and ‘source_daimon’ tables follow this comment.

In here, how can I connect the ‘daimon_type’ in the ‘source_daimon’ table?
I understand daimon_type has 0 to 3 and I connected like this.

0: CDM → CDM Database (ex. SJ_AUSOM_sample05)
1: Vocabulary → CDM Database (ex. SJ_AUSOM_sample05)
2: Results → OHDSI Database (ex. SJ_AUSOM_OHDSI)
3: Evidence → ?

but yet I don’t know what means the Evidence is.
Can you tell me what is the Evidence? and which one is the relevant one? (CDM Database? or OHDSI Database?)
