如何将大中型企业中各自分立的应用中核心及需要共享的数据以统一、权威的方式准确呈现，是实现企业进一步信息化的重要前提。提出一套数据交换整合体系，从各应用中分离主要信息，在保证数据质量的前提下，实现核心数据的集成、共享。以该体系构建的某集团公司数据处理平台，结合设计的扩展公式，以多层次的系统架构设计实现了多数据源结合的操作，同时设计了增强扩展性的数据扩展接口。该体系对大中型企业实现统一数据的信息化建设具有借鉴和推广意义。%It is an important prerequisite for realising the further informatisation of enterprises that to present the core and sharing data in discrete applications of large and medium-sized enterprises in a uniform and authoritative manner .In this paper we introduce a set of data exchange and integration system , which separates the main information from applications and realises the integration and sharing of core data under the premise of ensuring data quality .A data processing platform built for a group company with this system implements the operations of multiple data sources combination with the design of multi-level architecture in conjunction with the expansion formula of design , and meanwhile designs the data expansion interfaces for enhancing the scalability .This system has the significance of reference and popularisation for large and medium-sized enterprises to realise the informatisation construction in uniform data .
