Fan trap: one of the schema-tables in your physical realization via an rdbms has a 1:many relationship between two slave-tables but there is no path between the two slave tables! So we are clueless about the fk between them and the cardinality of the join is undefined leaving you powerless to query the data between the two slave tables

Chasm trap is a many-to-many join between two tables and requires a bridge table to resolve the context of the join.example:one product has one or many customer-orders and one customer has zero or many order-cancellations& returns
