Abstract: The establishment of archives information and archive management system changed the previous traditional manual file management mode, and has important meaning in the improvement of management ability and management efficiency. Through investigation and research of multiple users, we learned the system used by the users. After digestion and absorption, we developed the module to which users put the most attention of the archives management. Users can have comprehensive management of technical archives through our system, and check electronic files, etc.

Abstract: This paper introduces Internet search link analysis technology progress in recent years (1998-2005) , and puts forward some feasible directions for further research.

Abstract: The internet of things (IOT) is the key direction of a new generation of information technology innovation breakthrough in China, and it contains a huge space for the application of innovation. In the past few years, our internet of things technology (IOTT) research and application promotion has achieved initial success in many areas, especially in the intelligent construction fields. In this paper, we set the breakthrough point of the basic construction projects in the important cultural industry in Shandong Province --- Mass Media Building to analyze the application features of IOTT in the new modern intelligent building, and we explain the implementation patterns of each module of Weak Current System in detail.

Abstract: The idea and method of multi hiberarchy design for security is proposed in this paper with the basic theory of security for modern network. A detailed analysis on hiberarchy is done to figure out the potential security risk under various internal levels of an enterprise by deeply study on a dummy enterprise network. According to the principle of integrity, balance, combination of technology and management, a network security target which is fit for the requirement of enterprise is issued. And based on it, a total network security solution is proposed. This article focuses on the setup of firewall, design and setup of inbreak detection system, implementation of VPN and application of access control program. It also discusses the selection, setup and management system of the network hardware. This solution has a lot of advantages, such as high practicability, strong security, good performance-to-price ratio, easily exercisable, advanced setup and well extensibility.

Abstract: 3D virtual campus construction mainly includes several key techniques and links, such as material resources collection and processing (including campus CAD graphic design and material texture image), preliminary modeling of 3D building, models optimization and texture mapping, scene integration and rendering baking derived of 3D building and system integration platform and so on. This paper attempts to study the key technology and the specific production process in every link of 3D virtual campus system, and use professional software Uinty3D as the system integration platform, so as to construct a complete virtual campus system.

Abstract: Sensitive data in database should be encrypted to protect it from malicious access. Do this in application is hard and costly. Utilizing the user-defined function technology supported by database management system, data encryption could be done separately and transparently for application. The principle and system architecture of encrypting database content with user-defined function is introduced, and the method handling long object encrypting is discussed specially. Experiments show that the proposed method is easy to implement, effective in system running and application development, and applicable for both new developing and old developed application.

Abstract: With the rapid development of Internet technology and applications, online communication between teachers, students, and teaching management personnel becomes more and more frequent. Teaching management system based on web through school network may not only realize teaching information release and communication between teachers and students, but can achieve results release and student achievement inquiry, teaching evaluation, teaching plan search, and realize functions like teachers and students chat or answering questions. It is very necessary and also feasible.

Abstract: Smart campus is an inevitable trend in the development of digital campus construction. The internet of things and cloud computing are the key technologies in the construction of smart campus. The authors expound the concepts of smart campus and put forward overall architecture of smart campus based on the internet of things and cloud computing. They elaborate on the network foundation platform, service platform and the construction of intelligent application platform in detail. Finally, discuss the problems should be noticed in the smart campus construction.

Abstract: The computer simulation design technology plays a very important role in the construction of large venues, which can not only improve the quality of building construction but can provide information technology reference for the construction process. In the process of constructing sports venues, the lights of the stadium cannt produce vertiginous effect due to the need of indoor sports activities. By applying computer simulation technology, using catia software to build model for the venue and taking advantage of workbench software to make simulation for the light in the venue, this paper obtains the light effect of the stadium under the function of three kinds of tubes and the tubes of different intensity. Thus, it provides the technical reference for the application of computer information technology to the construction of sports venues.

Abstract: By applying the Auto LISP programming language to the design concept of AutoCAD, this paper realizes the secondary development of AutoCAD software. Through the Auto LISP design, this paper implements three kinds of constituted artistic effects for the fractal tree of landscape architecture, namely, plane, color and stereo. At the same time, this paper establishes the fractal mathematical models and algorithms for the landscape design. In addition, the entity model of landscape is built through the AutoCAD landscape design library and the fractal tree is established in the entity model. Through the three-dimensional rendering of plane, stereo and color, this paper achieves wonderful digital multimedia visual communication effect. Thus, it provides a technical support and theoretical reference for the computer simulation design of modern landscape.
