NHibernate：映射具有复合ID的一对一关系

Question

We have a situation wherein there is a Parent table and many Child tables. The Parent Table contains all transactions while the child tables are made to segregate specific type of transactions. The key structure is as follows:

Parent Table - Contains all Transactions

• Composite Primary Key
  • TranId
  • TranMonth

Children Tables - Contains Transactions of specific type

• Composite Primary Key (and also the Foreign Key from Parent table)
  • TranId
  • TranMonth

Request someone to help me out on how to map a one-to-one relationship between these tables in NHibernate.
