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 inmemory data management technology. Every distributed node initializes the hot data and creates index based on the user request in mainmemory columnstores. And it implements the data synchronization between the disk and inmemory as well as the data synchronization between distributed nodes and data center data node with transaction logs.

Key words: genealogy data, distributed structure, in-memory data management technology, indexing, data synchronization
