Abstract: Development of network technology makes people come into contact with more music mode, music online website as a network carrier, in the dissemination, creation, appreciation and other aspects have a profound impact on the development of music, the paper based on the .NET technology to design and build the music online website. Firstly, research the .NET three-tier architecture, constructed by the presentation layer, business layer, data layer MVC architecture diagram, and described the components; then, design website function, including foreground service and background management module were composed by the 10 sub-modules module; Finally, build .NET three-tier structure, the specific process is divided into eight steps and is described in detail. Contents of this paper have important implications for riching people's lives, active mass culture, and promoting the development of music and other aspects.

Abstract: Computer work is a combination of human and computer networks, software and hardware, and other related technologies for collaborative work methods. Technical support group members working computer system work together to share resources and information in an environment based together to accomplish a task applications. This paper describes a computer-based technology to build collaborative work the way the Japanese corpus, characteristics and significance, as well as teaching and research application.

Abstract: Connection pool is widely used in 3 tiers Web system based on database. It can improve performance of the Web system, but brings security problem to the system at the same time. The formal model of 3 tiers Web system is proposed, and the root of security problem, absence of subject transmission from Web application to database management system, is found from the model. In addition, several methods to solve the security problem faced by database connection pool in 3 tiers Web system are introduced or proposed.

Abstract: Along with higher vocational colleges and their internal units attaching great importance to the network publicity work continually to enhance, the number of various types of websites is in the rapid growth, meanwhile the website structures become increasingly complex and these websites are asked to provide more diversified services. The traditional model of website construction has been unable to meet the growing demand for construction and management of websites. SaaS (Software-as-a-Service) as a new software mode can provide convenient, fast and low-cost way to build network publicity support platform for higher vocational colleges. In this paper, we first introduce the definition and characteristics of SaaS, summarize the advantages of SaaS-based network publicity support platform, and then discuss the key technology for SaaS-based network publicity support platform related to the frame structure, system functionality and deployment. Finally, we introduce the application effect and the prospect of the platform.

Abstract: After analyzing the security issues database connection pool faced, the database connection pool audit system (DCPAS) is proposed. This system can trace the identity of the end user by binding the user's operation to their executing SQL statements, and make the end user auditing possible. The experiments show that DCPAS could audit the action of end user.

Abstract: RFID middleware is a key technology of Internet of things. It achieves data recognition and data filtering between hardware devices and software applications. A design scheme for RFID middleware framework is presented in the paper. According to functional analysis and layered design ideas, we define a hierarchy of RFID middleware and construct an application framework, in which RFID event manager module is responsible for processing data streams and RFID information service module is responsible for system integration. Simulation results verify the correctness of the design project. Its recognition rate, redundant data filtering capability and other performance indicators have reached the preset requirements.

Abstract: With the rapid development of Internet and the explosive growth of Internet information, massive data processing received more concerns. Micro-blog, which is an important representative pattern of the Internet development in the future, has become the essential tool of communication and marketing to all of us. Processing and using the massive data resulting from micro-blog activities has becomes a hot topic. In this paper, we propose a method to design and implement the User Interest Based Search Engine, a search engine can be used to search for the same interest micro-blog users. We at first crawl massive micro-blog data from micro-blog websites, and store this data in HBase. Then we process the massive data and build indices using MapReduce. Finally, we build a search engine web site based on Solr, and we propose a rank algorithm for searching. By employing this User Interest Based Search Engine, we can accurately search other users with the same interests as ourselves.

Abstract: In broadcast encryption system certain users may leak their decryption keys to build pirate decoders, so traitor tracing is quite necessary. There exist many codes based traitor tracing schemes. As pointed out by Billet and Phan in ICITS 2008, these schemes lack revocation ability. The ability of revocation can disable identified malicious users and users who fail to fulfill the payments, so that the broadcast encryption system can be more practical. Recently, Zhao and Li presented a construction of codes based tracing and revoking scheme which achieves user revocation as well as traitor tracing. However, their scheme is only secure against chosen plaintext attacks under selective-adversary model with random oracle. In this paper, we obtain a new construction of codes based tracing and revoking scheme which is proved secure against chosen ciphertext attacks under adaptive-adversary model without random oracle. Our idea is to insert codeword into Boneh and Hamburgs identity based broadcast encryption scheme to retain the ability of user revocation and use Boneh and Naors method to trace traitors. Our fully secure scheme is roughly as efficient as Zhao and Lis scheme while the security is enhanced.

Abstract: Enterprise applications office automation system can reduce the burden on staff, improve quality, and promote standardized management, improve the management level, thus promoting informatization construction. This paper launches the research in view of the difficult problems of enterprise OA construction. Firstly, it basics on the construction goal, function structure was studied by the personal office, administrative management, official document system, public information, administrative examination and approval, auxiliary office, system management seven big modules; then, research database platform, through a list of ways describes a list of design components, logic, and so on, Domino database component consisting of access control. Contents of this paper, for improving the level of enterprise information, improve office efficiency and achieve economic aspects of business by leaps and bounds and so will play a positive role in promoting.

Abstract: Software Quality scheme selection is an important pre-work of software project, For software quality evaluation index are difficult to quantify and has the characteristics of uncertainty, this paper uses a nonlinear SVM classification algorithm research. Firstly, to build a software quality scheme evaluation index system composed of 12 indicators, and through hierarchical structure analysis model representation; Then, research on support vector machine, using graphic to show that the basic idea, through mathematical model to describe the algorithm, constructed Sigmoid kernel function; Finally, to perform case analysis, through 8 have been evaluated schemes to train, drawn 4 unselected scheme evaluation results. This article will apply SVM to software quality scheme selection, it is SVM a new exploration in the field of software engineering, and to improve software quality has an important significance.
