Hi @Shrutii 

rev Cardinality is the reverse cardinality which you will b defining, if you have written the code in country schema then single cardinality will be create in the reverse way, ie, from recipient to country schema and vice versa. Reverse link [from recipient to country] will have single Recipient will have only one country (1-1) but forward [from country to recipient] will be one Country will have many recipients (1-N).

For more details you can visit the documentation.

Hi @Shrutii ,

Logically the relationship between a country table and customer table is 1 to Many.

But in general if you want to create 1 to 1 link between 2 schema, then you can write the join script in any of the schema. Example, if you write the join script in Table A, mention target="abc:table_B" in element tag. And if you decide to write the join script in Table B, mention target="abc:table_A" in element tag.
