It is so simply and quickly.2.1.4 数据管理能力要求Data Management Capabilities to Requirements数据库的需要巨大的存储容量，可以容纳大量的信息数据。同时也需要强大的数据管理能力，其中更新尤为重要。而
5、且数据库的备份和维护以及管理权限要求也需要有一个合理的分配。The database requires large storage capacity and accommodates the huge information data and also need powerful data management capabilities, including updating is particularly important. In addition, it is important for database to backup and maintenance. 2.1.5 故障处理要求Fa
6、ult Handling Requirements由于系统自己实时备份，所以所有出错都会仍然保留用户的个人信息和操作记录。数据库会对用户的数据存有备份，只有在出错时，这些备份记录被触发，依然可以保存客户的信息安全。在故障处理的速度上来算，平台需要很强的后台监控能力，要做到察知毫微，动之如电。故障发生时也会第一时间被通知管理员。Platform will save the users personal information and operating records whether to error in system because of the backup what is backup
