Getting Started with Object-relational Mapping

Abstract

In the introduction, I stated that the purpose of this book is to explore object-relational mapping (ORM) by examining the new tools, LINQ to SQL and EF, as well as tried-and-true design patterns. Unfortunately, to become a “professional” at ORM development, you have to start with the basics. This chapter introduces you, largely in a technology-independent manner, to some of the essential concepts of ORM. In addition to a basic examination of the “what and why” of ORM, you will also be exploring the qualities that make up a good ORM tool and learning whether LINQ to SQL and EF make use of them.
