Hi Steve,
Let's try a generic answer first.
1: Make one or more atomic statements that include your two "entities" as object type names.
2: Put the statements into NORMA.
3: Add appropriate constraints
4: Look at the Relational View.
If you got the constraints right, then NORMA should generate relations that include the two entity names as keys in the relations.
You can also use NORMA to generate the DDL.
Note: ORM uses "Object Types" which are not the same as "entities" in the ER paradigm.
