Starting with the syntax and common use cases for developing in Salesforce, this book will teach you how to create and deploy applications on the fly. You will learn how to approach new projects and learn the basics of Apex, including how to use Eclipse and the sandbox.

Salesforce limits and batch processes are explained in an easy-to-understand format, and you will gain a deep understanding of triggers, classes, test coverage, and Visualforce pages.
