摘要:在这个信息化和数字化的时代,越来越多的行业使用信息系统处理日常业务,存储在信息系统中的数据成为企业的重要资源,所以数据库的备份和恢复也显得非常重要,而自动化数据的备份和恢复更是带来了信息安全和操作便利的两大益处。本文归纳了手动备份和手动恢复在信息安全和实际操作上带来的不便,通过一些使用手动备份来备份数据库的案例总结了手动备份所涌现出来的问题。针对这些问题,查阅了历年来与备份与恢复相关的论文和文献综述,通过调查了解小型数据库的特点(种类齐全、面积较小与便利商店相似、在城市的小镇上较多)与需求得到的启发,设计了操作简单并且专属小型超市的信息备份与恢复系统,对该系统进行了基础的功能介绍和界面展示。81089

Analysis of database backup and recovery strategy of small supermarket
Abstract:In this information and digital age, more and more industries use information systems to process daily business and the data stored in the information system becomes an important resource of the enterprise, so the backup and recovery of the database becomes an important resource of enterprises, and automated backup and recovery is the two benefits of information security and operation convenience。 This paper summarizes the inconvenience caused by manual backup andrecovery, and summarizes the problems of manual backup by using manual backup to back up the database。 In view of these problems, the literature and literature related to backup and recovery over the years are reviewed。 Through investigation and understanding of the characteristics(full range, smaller and similar to the convenience store, more in the city of the town)and needs of small database, designed a simple and exclusive information backup and recovery system of small supermarkets, the system has been basic functional introduction and interface display。
