摘要: 针对集中式系统的查询功能存在设计复杂、查询速度慢、时效性差等问题,提出一种建立在分布式数据源基础上的通用解决方案,将大量数据进行分发,并采用反向的数据访问方式,以提高查询效率,增强扩展性,降低程序复杂度。实现一种可继承的组件装配式查询方案,可以简化开发部署工作,对不断变化的各种形式的业务需求做出快速响应。

关键词: 集中式系统, 通用查询框架, 依赖注入, 模板化设计

Abstract: The query function for a centralized system is usually hard to design and costs a large number of server resources. A solution based on distributed data source is discussed to solve these problems, which uses an inverse data access method to improve querying efficiency and reduce programming complexity. It also contains an inheritable module-assembling query scenario to simplify the process of development and deployment, in order to meet the complexity of business requirement.

Key words: centralized system, general query framework, dependency injection, template design
