Java是通过JDBC技术实现对各种数据库的访问的,JDBC是Java数据库连接技术的简称。它可以把数据持久保存,是一种持久化机制。 1.持久化 持久化就是将程序中的数据在瞬时状态和持久状态间转换的机制。 2.JDBC API Connection连接接口 Statement接口 ResultSet结果集接口 PerparedStatement接口 3.JDBC Driver Manager(驱动...
The implementation of this data source opens and closes the connection every time it is requested. Although a bit slow, it is a good choice for simple applications that do not require high database connection availability. Performance depends on the database used. For some databases, the use o...
1、JDBC(Java Database Connectivity) JDBC 是一种用于 Java 应用程序与数据库交互的 API(应用程序接口),提供一组标准的接口,允许 Java 程序执行 SQL 语句、获取查询结果及处理数据库事务。 2、连接池(Connection Pool) 连接池是一种管理数据库连接的技术。它维持了一个预先创建的数据库连接集,应用程序在需要时可...
