学习Ibatis的简易教程：配置和操作数据库，包括读取、添加和删除数据。

Ibatis is a lightweight, simple tutorial that guides us through the process of using and learning iBatis, helping to understand the framework. iBatis is a data persistence framework similar to Hibernate, JDO, and EJB, but it differs in that it maps objects to SQL statements and uses existing SQL and stored procedures to handle databases. This tutorial will walk you through the process of configuring iBatis to run a small program, breaking it down into several separate examples. The first example will demonstrate how to retrieve records from a database, using MySQL 5.0 in this case. The example will focus on retrieving contact information from a 'contact' table. Following this, the tutorial will cover how to add more data to the database and how to delete data from records using iBatis. Overall, this iBatis tutorial is a comprehensive guide to understanding and using iBatis, providing step-by-step examples to help users master the framework. With its clear explanations and practical examples, it is a valuable resource for anyone looking to enhance their skills in database management and manipulation using iBatis.
