基于SOA和工作流的数据仓库更新系统

针对数据仓库系统中的异构数据源集成问题和数据仓库更新流程的控制问题，提出一个基于SOA和工作流的数据仓库更新系统，把异构环境下的各个系统作为服务提供者或服务消费者，抽象出标准的功能服务接口，实现了异构平台的系统集成。同时把数据仓库更新过程定义为活动的集合，从逻辑上看作为一个工作流过程，可以根据不同的业务需求进行动态组织，高效地满足用户的需求，提高了更新流程的自动化程度和效率。

DATA WAREHOUSE UPDATING SYSTEM BASED ON SOA AND WORKFLOW

In this paper,aiming at the problems of heterogeneous data resource integration and data warehouse updating process control in data warehouse system,we proposed an updating system of data warehouse based on SOA and workflow.It deems every system in heterogeneous environment as a service provider or a service costumer,abstracts some standard service interfaces and implements the system integration of heterogeneous platform.At the same time,this system defines the data warehouse updating process as a set of a...
