Oracle数据库基本操作及Spring整合Oracle数据库详解_Oracle

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
