摘　　要：面对常规的报表查询系统、跨平台系统受到活跃分布式数据影响,导致检索和存储服务效果较差的问题,为此,提出了基于跨库检索的分布式数据服务系统设计。对数据服务器进行分布式设计,计算所有数据的唯一散列,并从服务集群中选择相应的数据服务器。数据存储服务器需要确保数据的存储完整,用户通过客户端向集群服务器发送相应数据,保证了数据传输的安全性。设计检索调度处理流程,方便用户检索数据。分析分布式数据活跃度,使用一致性哈希算法存储活跃数据,使分布式数据快速定位到对应服务器中。由功能测试结果可知,该系统最高检索精准度为1.0,存储范围与实际存储范围一致,具有良好的检索和存储服务效果。Facing the problem that the conventional report query system and cross platform system are affected by active distributed data,resulting in poor retrieval and storage service effect,a distributed data service system design based on cross database retrieval is proposed. The data server is designed distributed,the unique hash of all data is calculated,and the corresponding data server is selected from the service cluster. The data storage server needs to ensure the integrity of data storage. Users send corresponding data to the cluster server through the client to ensure the security of data transmission.Design the retrieval scheduling process to facilitate users to retrieve data. Analyze the activity of distributed data,and use the consistent Hash algorithm to store the active data,so as to quickly locate the distributed data to the corresponding server. According to the function test results,the maximum retrieval accuracy of the system is 1.0,the storage range is consistent with the actual storage range,and has good retrieval and storage service effect.
