异构数据源间数据转换技术的研究与实现

Technical Study and Implementation of Data Transformation Between Heterogeneous Data Sources

就数据转换的实现,提出了“一种数据、两种变换”的技术思想,在有效地降低数据转换代码与各种形式的物理数据源以及复杂的业务规则之间耦合度的同时,提高了数据转换代码自身的内聚性,从而实现高效、灵活的数据转换。该项技术研究已被成功地应用于“城市实有人口库管理系统”和“城市GIS综合应用平台软件”和“公安数据转换与请求服务平台”。

A“one type of data, two types of transformation” technical schema is introduced to accomplish implementation of data transformation, which efficiently reduces the coupling between the implementation and various data sources or complex business rules, and improves the cohesion of the implementation itself as well. Consequently, it is possible to implement efficient and flexible data transformation by such a schema.
