Resolving Many-to-Many Relationships

  • ·         A relationship that participates in an entity's unique identifier. – barred relationship
  • ·         The product of the resolution of a many to many relationship. – intersection entity

1.      Resolve the M:M between TEACHER and CLASS as well as INTERPRETER and LANGUAGE. 
For each intersection entity, think of additional attributes like a UID.

For intersection entity InterpreterLanguageMap, interpreterId from teacher entity and languageId from class entity make unique identifier.
