Application of inmemory data management technology in genealogy information system
-
摘要: 设计并实现了具有数据录入、数据服务、数据输出功能的族谱信息系统. 族谱信息系统采用了分布式结构,在每个分布数据节点引入内存数据管理技术,采用列存储模型,自动初始化热点数据,并根据用户请求组织数据建立索引,同时利用事务日志对每个分布数据节点的内外存进行数据同步,对中心数据节点和分布数据节点进行数据同步.Abstract: In this paper, a new genealogy information system was designed and implemented. It provides data inputting, data service and data outputting functions. The new genealogy information system is based on the distributed structure. Its distributed nodes employ the inmemory data management technology. Every distributed node initializes the hot data and creates index based on the user request in mainmemory columnstores. And it implements the data synchronization between the disk and inmemory as well as the data synchronization between distributed nodes and data center data node with transaction logs.
