Abstract: The GIS system is a computer system consisting of software, hardware, and to describe the geographic information,and subsidiary information data. The underground gas pipeline is a new application field of GIS system, realizes the electronic and information technology infrastructure information management of gas pipe network, as the transmission and distribution scheduling, document management, network planning, network provides modern means of emergency decision, the daily operation management, construction management and auxiliary decision and other gas.

Abstract: Moodle is a completely free open source course management system, according to the basic principle of pedagogy related; it aims to help teachers to create a effective learning community. Moodle platform used in the computer specialized curriculum teaching, enables students from the inquiry learning, autonomous learning, cooperative learning and so on several aspects to improve the effectiveness of professional course teaching. And interactive evaluation as an important component of Moodle teaching platform, directly affects the network curriculum teaching effect and quality.

Abstract: By using WebGIS technology and designing the traceability database of the production, wholesale and sale information of agricultural product, the agricultural product traceability information system based on ArcGIS server is developed and some functions are implemented. Firstly the production place, wholesale place and sale place of the agricultural product is visualized . Then the information of agricultural product is queried and analyzed quickly. At the same time, the shortest path analysis of production place, wholesale place and sale place is implemented. Finally, by using the relationship of production, wholesale and sale of agricultural product, the traceability of agricultural product is researched and implemented.

Abstract: Sport E-government platform is an important means to share sports information resource, to promote sport administration and sport management information, to strengthen sport events management and sport venue construction. For the status of software development in platform building process, this paper studies software framework. First, according to the standards and norms of the national E-government construction, combines with the experience of the sport E-government construction, researches software functional framework; Second, researches SSH-MVC technical framework for developers to accomplish specific business processes on top of the frame; Finally, researches three-level security framework consisted by client, Web server, enterprise-grade information system. The content of this study, improves the level of sport E-government, reduces the technical requirements of developers, changes the traditional software development model.

Abstract: In this paper, the program in Simao district of Puer city is the object of this study, the latest investigation data of the land use status, the topographic maps and the rivers are chosen as the source data of this program. Under the support of GIS technology, we have a specific implementation of the Spatio-temporal data of the land use. The results of this research show that the land use information system based on GIS technology can provide an advanced system for decision-making to the land administration department.

Abstract: In the modern information society, e-commerce enables furniture enterprises and individuals that master information technology and commercial rules to employ all sorts of electronic tools and network in a systematic way and to engage in all kinds of commercial trade activities that are realized with the electronic mode with high efficiency and low costs. In order to better develop e-commerce, furniture enterprises should make an analysis of demands on e-commerce and define the goal, guarantee of organizations, go on Strategic planning, evaluate its effect.

Abstract: In order to realize the digital school, the school network is realized information sharing and service sharing by SOA. In the paper, the logic architecture of digital school is presented, including the user interface layer, the service control layer, the department service layer, the business logic layer and the data persistence layer. And the UDDI system of school network is designed of data management module, user management module, system log, UDDI server, Web manager and UDDI client.

Abstract: This paper focuses on risk management in each phase of life circle of software development and intrduces advisable measures for each risk. Secondly, it presents a formula to calculate risk. In the end, we analyze the sensitivity of risk by illustration, through sensitivity analysis can we find the most dependent index which can provide great assisstance.

Abstract: In the traditional file system, The lack of contact between the file name and the data content led to waste a lot of availability storage space, especially in large data archive storage system. This paper designs and implements a scalable multimedia archive storage system, called IMCAS. IMCAS use CAS store the archive data and use real-time monitor program automatically extract metadata information. through dynamic loading extraction module, the system can support variety of multimedia form.

Abstract: There are various calculations, transmission, and storage devices in terms of performance or reliability characteristics in great physical differences exist of large-scale cluster storage systems. Meanwhile, the actual traffic load data access for storage devices is also not uniform in space and time and there is a big difference. It is unrealistic and unwise if all the data stored on the high-performance devices. In order to resolve this problem effectively, we propose large-scale adaptive tiered storage system architecture in which structure can carry out effective monitoring access to the load and adapting allocation of storage resources based on the application environment. This can fulfill the full potential to the advantages of high-performance storage nodes to improve the performance of large-scale clustered storage systems.
