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.
In this paper, a new genealogy information system was designed and implemented. Itprovides data inputting, data service and data outputting functions. The new genealogy informa-tion system is based on the distributed structure. Its distributed nodes employ the in-memory da-ta management technology. Every distributed node initializes the hot data and creates index basedon the user request in main-memory column-stores. And it implements the data synchronizationbetween the disk and in-memory as well as the data synchronization between distributed nodesand data center data node with transaction logs.
