Let E1 and E2 be two entities in an E/R diagram with simple single valued attributes. R1 and R2 are two relationship between E1 and E2, where R1 is one-to-many and R2 is manyto-many. R1 and R2 do not have any attributes of their own. What is the minimum number of tables required to represent this situation in the relational model?
