TSM - The analysis of Object -Relational Mapping (ORM) mechanism with Hibernate examples

Anghel Contiu - Senior software developer

Object / Relational Mapping (ORM) is a programming technique that provides programmers with means of accessing and manipulating the application objects without being interested in where these objects come from. This technique has emerged because of the need to overcome the paradigm difference between the object oriented model (sustained by the current high level programming languages) and the relational model (used by the most popular database management systems). This problem is also referred to as the object relational impedance mismatch.
