Oracle数据库基本操作及Spring整合Oracle数据库详解-牛翰网

一、Oracle数据库介绍

1、Oracle: 中文意思：神谕是由美国Oracle公司开发的一个面向对象、关系型大型数据库。

版本：2.0 3.0 ….. 9i(Internet) 10g(g：网格) 11g 12C

2、Oracle数据库的特点

大型的、安全性高、费用高

3、Oracle数据库的基本操作（权限）

默认三个角色：Sys （超级） System（DBA：数据库管理员） scott(学习账号) tiger

所有的操作都必须有权限：System

Sql：

DDL: 数据定义语言（create drop alter）

DCL: 数据控制语言（Grant：授权 Revoke：收回 Deny：拒绝）

例如：授予某个用户的select权限：

Grant select on 表名 to 用户
Grant select,update,delete on 表名 to 用户

Revoke select on 表名 from 用户

DML：数据操作语言：update delete insert

DQL: 数据查询语言： select

TCL: 事务控制语言： commit rollback

创建表空间

删除表空间

创建用户

授权：授权abc用户可以连接（connect）且操作资源（resouce）

二、SpringBoot整合oracle

导入依赖
