Data query system and method

The invention discloses a data query system and method. The system comprises a relational data engine and a data warehouse; the relational data engine comprises a data query module, an interface configuration module and a metadata table for associating the data query module and the interface configuration module. The data query system has the advantages that separation of interface configuration and data query business logic is achieved, project structures are clearer, role assignment is clear, interface configuration of a query interface is achieved, the configured interface takes effect immediately, restarting and reprogramming are not needed, user experience is improved, and usage efficiency is improved. 本发明公开了种数据查询系统及方法，系统包括：关系数据引擎和数据仓库；关系数据引擎包括：数据查询模块和接口配置模块，以及将数据查询模块和接口配置模块关联起来的元数据表。本发明的有益效果是：实现接口配置与数据查询业务逻辑的分离，项目结构更加清晰，角色分配明了，实现查询接口的配置界面化配置，配置的接口立即生效，无需重启无需重新编程，提升用户体验，提高使用效率。
