To demonstrate many to many mapping using hibernate annotations, we will associate two entities i.e.ReaderEntityandSubscriptionEntity. Their database schema is given in the image. Using these tables, any application can save multiple associations between readers and subscriptions. 1.1. Unidirectional Th...
