JDBC - JAVA DATABASE CONNECTIVITY

JDBC的三大主要功能：

JDBC helps you to write Java applications that manage these three programming activities:

1. Connect to a data source, like a database
2. Send queries and update statements to the database
3. Retrieve and process the results received from the database in answer to your query

简单说来，就是连接数据库，查询，返回数据。
