A middleware-based implementation for data integration of remote devices

Data integration is the fundamental to global Enterprise Application Integration (EAI) and Business Intelligence (BI) for decision support in a company. Different from those existing solutions offered by IT companies and other techniques, like Web Service, which usually are approaches for data integration on high-level, we contribute a novel solution for data integration of remote devices on low-level. This paper describes a fully scalable and configurable middleware which uses a range of technologies-Component-Oriented Programming, Message Queuing, XML and Topic-based Publish/Subscribe design pattern-to release the power of parallel processing with distributed data. Steps for the design and implementation of remote data integration middleware are the main topic of this paper. It is designed as a soft-gateway to link upper-level PCs with lower-level data transfer units, and implemented by extracting the key part of data communication out of its original holder so that the UI only cares about how to display data.
