摘要
对于大型信息系统而言,采用单一的数据库设计,随着信息的日积月累,会给信息系统的运行产生诸多负面的影响;根据信息和业务的特点,采用多数据库的架构,设计前台业务数据库、后台业务数据库、历史数据库、统计数据库、基础数据库和备份数据库等,同时设计一种数据调度机制,在各类数据库之间进行数据调度,从而提高信息的使用与维护效率,进而有效地保障信息系统运行的稳定性与流畅性。
For a large information system, using a single database design can make plenty of negative impacts on the operation of the information system with the accumulation of information. According to the characteristics of information and business, design the front desk business database, background database, historical database, statistical database, basic database and backup database by using multiple database architecture. At the same time design a data scheduling mechanism, do data scheduling among the various types of databases to improve the efficiency of the use and maintenance of the information and thus effectively guarantee the stability and smoothness of the information system running.
