The Research on Application of SOA-Based Data Mining Serviees on petrochemical industry ABSTRACT With the Continuous development of theory and application research on Data mining(DM), the technique has increasingly shown its significant place in the enterprises information decision-making and supporting system, and has been one of the key components in the enterprises informationization strategies. For most of petrochemical enterprise,one of the common characteristics is the great amount of product, information flow and capital flow. Applying the technique of DM in the analysis of the information mentioned above will mean significance in improving the effectiveness and lowering the cost of the petrochemical enterprise running. The article centres on A group co., LTD. Real-time database implementation project. Firstly, the article outlines with the important significance of constructing real-time database at A group co., LTD. Secondly, by adopting international advanced software and mature technology, we combine with the characteristics of A group co., LTD requirements, introducting the process of real-time database integration platform. We also solve the key technical problems, such as the implementation with a variety of data acquisition system docking (DCS system, PLC system and SCADA system, electrical system, etc.); The PI System can collect, store and manage the real-time data in the process of production and analysis of the historical production data of a long cycle. Then according to the needs of the business, the PI System can achieve the effect of statistical form, equipment operation monitoring and business operation monitoring. The real-time database system can also provide various applications such as producting data to ERP. Finally，this article summarized the research achievements and things we can improve, and prospected the research works we should intensity in the future.
