Abstract: Cloud computing is a new concept emerged in the IT sector in recent years. Cloud computing can be used more easily and quickly in financial applications, adjusting resource being used by accounting software dynamically, reducing overall investment in accounting modernization, improving the utilization and the effect of IT equipment. In this paper, starting from the concept of cloud computing, we summarizes the status of development of accounting modernization, and discusses the cloud computing service model, the applications of cloud computing in the accounting modernization as well as the advantages and problems.

Abstract: The safety issue of cloud computing arouses much attention recently. In this paper, it is firstly introduced the related concepts, then it is introduced the current situation of cloud computing as well as potential safety hazards and security reference model. The conclusion is drawn in the end of this paper.

Abstract: With the popularity of the cloud computing, network technology obtains unprecedented development and revolution. Cloud computing is the direction of cyberspace storage in the computer and internet filed. Big data and multi-dimensional storage and calculation along with the cloud computing. Therefore, internet data security is the key point. For example, based on the cloud environment, the big data transmission and storage requires encryption technology. This article will research the data security of cloud computing, design the service model of data security encryption, and realize data transmission and storage security service of computer and internet cloud environment.

Abstract: Based on the study of abroad foundation on visual theory, we conduct depth discussion of the current introduction of visual teaching meaning. For the current computer graphics course content, we determine a visual teaching content and objectives, carry out the study and practice of computer graphics algorithm visualization teaching. This paper uses VB 6.0 visual programming tool to generate the basic primitives, polygon filling, cut a straight line segment, curve generation and visualization of fractal algorithm design and realization. Through analysis, this paper hold that use of visual teaching has a positive effect and influence for professors to change the way teachers help students understand computer graphics algorithm. In the process of teaching, students improve the understanding, exploration, discovery and creativity through observation, conjecture and verify.

Abstract: With the continuous development of technology, a variety of computer and mobile devices constantly creat huge amounts of information, this phenomenon will continue to repeat, and today's world has been transferring towards "big data" era. The arrival of the era of big data of the computer information processing technology has brought a very big impact. This article describes the computer information processing technology, pointed out the lack of background in big data computer information processing technology and make its application and development prospect analysis.

Abstract: Big data is one of the important development direction of modern information technology, realizing the sharing and analysis of large data will bring immeasurable economic value, but also has a tremendous role in promoting the social. In the age of big data, unified the data representation, large data processing, query, analysis and visualization are the key problem to be solved urgently. In order to provide a standardized framework construction of the large data service platform, this paper designed a large data service oriented architecture user experience. Secondly, in the aspect of data model, in order to achieve high data service for non structured data, the design of the non structured data model based on subject behavior. In large data service model, algebraic model large data services and their composition was established by using process algebra. In large data service applications, detailed retrieval, process analysis and visualization services, and by improving the retrieval accuracy and efficiency of the service in two aspects of measures to achieve the high data service optimization.

Abstract: The thesis is based on the university network management work in combine with the characters and requirements of the school. A service-oriented architecture is adopted to integrate multi-business systems across different platforms. The unified authentication, single sign-on, data exchange and share are implemented. It improves the school normalization level, broadens society service fields of the vocational colleges at the same time avoids the rebuilding in the normalization work and saves the investment. A reliable information base is supplied for the next stage virtual campus construction.

Abstract: The electric power enterprises are closely related to the national welfare and the livelihood of the masses, nowadays are faced with the challenges from monopolistic management to the competition in the market. In this paper, building performance management system based on neural network for power supply enterprises to evaluate operating performance demonstrated the practical value of the model. Based on the summary of private listing performance management system on the basis of relevant literature, from the financial perspective and non-financial perspective of the establishment of private manufacturing listing performance management system, and constructs the neural network based on neural network and model performance evaluation system. Neural network model of the application results show that the neural network in the performance management system application feasibility. From the shareholders' interests, performance management system can improve the operating performance of the related suggestions in the financial and non-financial aspects.

Abstract: The online examination system based on Web technology development, adopts B/S model of three-tier architecture and uses ASP.NET technology, AJAX technology JAVA programming language and SQL Server 2012 as database management system On the base of analyzing the requirement of network examination, online examination system was designed uniformly and system adopted genetic algorithm to generate test paper. In the design of examination system, XML technology was combined with database technology, which adopted XML to describe exam papers, played XML technology in the data description and data exchange and display of superiority to improve system performance. In this system, students can take the exam and choose their own learning content to take self-test exercises. When self-test is completed, students can view their own answer situation and the standard answer of these questions; this played a role in promoting students' independent learning.

Abstract: With the development and popularization of computer, network video teaching is the new medium of school teaching. But because the scale of network video teaching system and broadband carrying capacity are limited, network video is hard to satisfy the massive need in school, thereby it could lead to sharp drop in network video teaching quality. Through establishing a simulation platform based on OPNET, the article analyse the video teaching system under network construction of school network; compare and discuss a optimization program of network current-limiting; and make a simulation test on optimization program of network cureent-limiting. The result show that through selecting right optimization program of network cureent-limiting, we can make s big promotion in system carrying capacity, and enhance the user’s video-teaching experience.
