【摘要】 提出了一种利用数据库分区技术对超大数据量的数据库进行存取和处理的解决方案．以全国人口信息系统数据库为例,从经验的角度介绍了数据库分区的概念和原则,又提出了多种可选的分区方案并从多个角度分析了各种分区方案的优劣,还对选定的分区方案进行了查询等操作的效率验证．该方案的分区设计有效地提高了系统的可管理性和可维护性,使海量的数据存储与处理成为可能,也为类似大规模数据量的系统存储设计提供了参考．更多还原

【Abstract】 A solution of mass data storage by database partitioning technology is proposed. Using partitioning technology in a Country-wide Population Information System as an example, it states the concept and principals of database partitioning technology. It also provides several selections of partitioning models and their comparison as well as their querying efficiency validation. The design of partitioning improves the system manageability and maintainability and enables mass data storage. It is also referable for those systems which need to handle the large scale data storage.更多还原
