事务就是一组有相互关联的工作，在普遍情境下都需要对这些工作进行合理的管理，所谓合理，有一个重要的概念：ACID
Atomicity原子性：同一个事物必须同时回滚或提交
Consistency一致性：在一个事物的的执行中，数据库必须处于一致的状态
Isolation隔离性：多个独立事物之间的交互深度，隔离性是一致性和并发性（Conccurency）之间的杠杆
Durability持久性：一个事物提交后，数据库或JMS提供者]]>https://blog.youkuaiyun.com/geminiroy/article/details/6333734https://blog.youkuaiyun.com/geminiroy/article/details/6333734geminiroyTue, 19 Apr 2011 15:38:00 +0800https://blog.youkuaiyun.com/geminiroy/article/details/6288812https://blog.youkuaiyun.com/geminiroy/article/details/6288812geminiroyWed, 30 Mar 2011 15:00:00 +0800
ORACLE中，表空间是数据管理的基本方法，所有用户的对象要存放在表空间中，也就是用户有空间的使用权，才能创建用户对象．否则是不充许创建对象，因为就是想创建对象,如表,索引等，也没有地方存放,Oracle会提示:没有存储配额．
　　因此，在创建对象之前，首先要分配存储空间．　　
  分配存储，就要创建表空间：　　
  创建表空间示例如下：
  CREATE TABLESPACE "SAMPLE" 
    LOGGING
