Research on negative association rule in multidimensional data mining is few. In this paper, an algorithm MPNAR is put forward to mine positive and negative association rules in multidimensional data. With the help of the basis of the minimum support and minimum confidence, this algorithm divided the multidimensional datasets into infrequent itemsets and frequent itemsets. The negative association rules could be mined from infrequent itemsets. Relative to the single positive association rule mining, the new additional negative association rules need not repeatedly read database because two types of association rules were simultaneously mined. Experiments show that the algorithm method is effective and valuable.

This work studied the situation of today’s data integration. To better solve the complexity and diversity in data integration, we propose a new idea of data integration service platform based on SaaS. The model architecture of data integration and its work principles are introduced. In the platform source data and result data are two interface.in the form of service. In the data integration platform, data are filtered and combined. the data are produced by the users’ requirements. Users call SaaS service to get the data that they wanted. Finally we analyze the model’s characters. This model of platform is more intelligent, efficient and personalized in solving complicate data integration.

This paper studied the Service-oriented software architecture. Recently service-oriented architecture is a research hot because it is open and flexible. But all people only concern its application in a certain field. Almost no one puts forward a general method for various field systems. Also there are no service-oriented developing software and tools. This paper proposes a service-orientation solution to the management information system based on SOA (Service-oriented architecture). Business process can be designed by interactive interface library. Users can complete the design of system by simply dragging the mouse. For various systems it is an efficient method because business process can be designed by interactive interface.

This paper studied the traditional supervisory control and data acquisition and investigates what is the most important in pipeline gas management system. Then a novel scheme is proposed for remote control interface on pipeline gas providing management. This scheme introduced GPRS and internet network technology to the traditional supervisory control and data acquisition. The details of System topological structure is given and Remote control interface structure are listed. At last, the system performance is analyzed and the results indicate that pipeline gas management system using remote control interface has the excellent protection performance and operability of RCI. It can meet the demand of intelligent home and intelligent building.
