动态数据服务发布引擎设计与实现

DESIGN AND IMPLEMENTATION OF A DYNAMIC DATA SERVICE PUBLISHING ENGINE

针对数据分散、格式不一、数据共享困难的问题,提出将多源异构数据动态统一发布成数据服务方法。设计研发一套基于B/S架构的动态数据服务发布引擎,以Restful架构风格实现对服务使用者的调用请求进行识别、解析、校验、操作执行,并将执行结果返回给服务请求者。解决了数据模型的异构性、数据抽取、数据合成等问题。

According to the decentralization,format differences and sharing difficulties of data,a data service method is presented,which integrates data of different sources and formats. A dynamic data service publishing engine system based on B/S architecture is developed. The Restful architecture style was used to identify,parse,verify and execute the call requests of service users. And the execution result was returned to the service requester. Thus the issues of heterogeneity of data models,data extraction and data synthesis and so on are handled.
