摘要
异构数据异构性主要表现在不同的数据库类型和数据结构。为解决异构数据整合中的统一检索问题,以科技资讯库、政策库、统计库、项目库、机构库和人才库为例,建立不同类型文献资源元数据结构和规范,构建吉林省区域创新数据库系统,解决不同种类数据库之间的数据整合问题。实践证明,基于该方式构建的区域创新数据库可为后续学科个性化服务提供有效的检索支撑,在系统利用和服务方面具有一定实用价值。
This research mainly solves the problem of unified retrieval of heterogeneous data integration which is mainly manifested in different database types and data structures.Taking science and technology information database,policy database,statistics database,project database,institution database and talent database as examples,this paper designs the metadata structure of different types of literature resources and establishes the metadata of literature resources.According to the standard,the regional innovation database system of Jilin Province is constructed to solve the problem of data conversion between different kinds of databases.The practice proves that the unified retrieval platform of regional innovation database based on this method provides effective retrieval support for the personalized service of the follow-up disciplines and has a certain practical value for the utilization and service of the system.
