1、7 系统出错处理设计 System error handling design（撰写人：杨林森 3112101126 Yanglinsen 2102-011-0300）7.1 出错信息Error message在软件的开发过程中， 需要对软件中存在的漏洞立即进行处理， 即使一个很小的漏洞，也会造成整个软件开发系统的垃圾资源无限增多， 最终可能会导致系统的瘫痪。因此在系统设计中， 对拟开发系统要注意数据的约束性。 为了进行数据统一收集和规范数据统一格式方面管理者的处理， 针对存在的安全隐患， 本项目组进行了统一约束规范。 同时，项目组也应该解决 Web服务器端的信息安全问题，这样才能更好的运用管

2、理系统， 从而减少系统的维修次数， 确保系统的安全使用。In the software development process, the need for software vulnerabilities that exist in immediate treatment, even a small flaw will cause garbage resources of the entire software development system and the infinite increase, may eventually lead to paralysis of the system

3、. Therefore, system design, system development should pay attention to the proposed binding data. In order to deal with a unified data collection and standardized data formats unified manager for security risks, the project team conducted a unified constraint specification. Meanwhile, the project te

14、来提高安全水平，这是用户和信息服务管理部门可做得到的。All systems, regardless of which way the use of development are inevitable weaknesses. Therefore, not only in the information management system at this level and be designed to review and propose security issues in computing center at this level (if applicable, including r

15、emote device). By identifying weaknesses in the system to reduce the risk of security violations, and to take the necessary precautionary measures to improve the safety level, which is the user and theinformation services department can do it.1）后备技术Back-up technology由于现代计算机科学技术的快速发展， 以往的数据备份已经不能满足用户

16、和管理者对现有系统的要求， 现在的技术一般是进行系统数据库的实时备份和备份服务器。当数据库瘫痪时， 通过快速进行系统库的切换， 这样可以有效的减少数据的丢失。当用户量大时， 也可以使用备用服务器， 两个服务器进行同步数据存储，如果一台服务器出错时， 可以转换到另一台进行相同的操作， 让用户不需要因瘫痪而面临网页打不开、数据丢失等相关问题。Due to the rapid development of modern computer science and technology, previous data backup and managers have been unable to meet

17、 the user requirements of the existing system, and now the technology is generally carried out in real-time backup system database and backup servers. When the database is paralyzed by rapidly switching system libraries, which can effectively reduce the loss of data. When the user capacity, you can

18、use the backup server, two servers synchronize data storage, if a server error, can be converted to another the same operation, so that the user does not open the page because of paralysis of face , data loss and other related issues.2）降效技术Drop-efficient technology通常情况下系统的管理员都不是专业的计算机人员，对计算机专业的知识了解相

19、对较少。在面对系统瘫痪等错误时，都不知道如何去解决问题。如今，随着计算机科学技术的飞速发展， 为了让系统用户能够自行解决运行过程中遇到的问题，大多采取小型服务器作为后备技术。这项技术在现有的开发系统中使用很广泛，当然备用的服务器从价格上考虑，可能不如主服务器， 也可能会降低工作效率，但是从数据的完整性和安全出发，可以让维修人员有更多时间进行系统的维护。Normally the system administrator is not a professional computer staff, relatively little computer expertise to understand.

20、 In the face of system failures and other errors, do not know how to solve the problem. Nowadays, with the rapid development of computer science and technology, in order to allow system users to solve problems encountered during the operation on their own, mostly taken small server as a backuptechno

21、logy. The technology used in the existing development systems is extensive, of course, the backup server from the price considerations, may not be as the primary server, it may decrease work efficiency, but starting from the integrity and security of data, allowing maintenance personnel more time fo

22、r system maintenance.3）恢复及再启动技术Recovery and re-start technology由于采取的是低端服务器， 同时进行数据库的实时备份。 这样在系统维护好完成后，可以很快的进行数据同步，同时也可以很快的进行系统的运行。To adopt a low-end server, while the real-time backup of the database. So that system maintenance is completed, you can quickly synchronize data, but also can be quickly carried out the operation of the system.7.3系统维护设计System maintenance design信息管理系统不同于其他系统，它并不是一劳永逸的最终系统。在它的运行过程中，还有大量运行管理、系统维护、系统设置等工作要做。交付使用的信息管理系统跟工业产品不同， 工业产品可以先生产一个样品，经过试验、改进再正式投入批量生产， 而信息管理系统它需要在用户使用过程中不断完善。系统维护包括程序的维护、数据文件的维护、代码的维护等，而且系统的修改，往往会造成系统程序、文件、代码的修改。因此
