Avoiding the Pitfalls of Object-Relational Mapping

Chapter 11 discussed a typical interaction between an application and a database and explained ORIM (object-relational impedance mismatch) and how it affects performance. It also stated that any potential solution should allow operating with large objects (i.e., datasets) and should support the exchange of complex objects. This chapter introduces an approach developed by us and successfully utilized in a production environment. This approach is called NORM (No-ORM).
