Design And Implementation Of A Multi-tier Architectural Special Resources Management System Based On B/S

Special literature refers to publication and acquirement are special scientific literature, it generally includes conference documents, technical report, patent literature, degree thesis, standard document, science and technology archives, etc. Special literature distinct characteristics, has extensive content, huge number and high reference value, it is very important sources for information retrieval, occupies an important position in scientific research, it is one of the important research subject in academic library and intelligence。Along with the Internet and WEB technology development, the Special Literature Management System (Special, Management System) became the product of the era, it makes full use of network and computer technology, for Special Literature organization, storage, released on the Internet for users to use. How to effectively to mass digital information organized, retrieval, access to and use of, and how to provide readers through the network information service problems such as these, become the special literature digitization construction of research hotspot.This article from this unit's years books management reality, on the summary and extensive reading of related literature at home and abroad on the basis of library special literature, combining participate in the design and development of experience for the current special literature system framework, safety and generality is analyzed and studied.Firstly, this paper expounds the research background and systematic research of purpose and meaning. Combining the current system in use process appears safety and generality, combined with XML technology has shielding ground floor various hardware platform and database management system, and puts forward the advantages of introducing XML technology concepts, and in the current information interaction mechanism model is improved, was put forward for the special literature system model of the system.Secondly, from special literature management system based on the framework design, be comprehensively introduces management systems design principle and realization method. This part, B/S, C/S, asp.net, ado.net, C# technology analysis, combined with the actual needs of system implementation, based on B/S architecture, the software design of the user interface layer, business logic layer and data services such as the layer structure system composed of improvement, and with asp.net, ado.net, XML technology realization, such as reducing authorized management complexity, reduce the management cost, strengthen information control flexibility demand.Third, system management module, resource management module, user retrieval module are analyzed, and the use of advanced UML object-oriented technique and facing the data flow demand analysis of structural study methods of analysis and design, complete the whole system of reasonable structure. System module mainly complete user management and user access control, resource management module mainly complete later resources processing, update, file upload, etc, the user retrieval module mainly realizes user for special literature resources of retrieval, browse and download, and other functions. In facing the end user interface, the use of using multiple conditions, many retrieval item retrieval scheme, convenient for the user, improving the precision.Finally, this paper introduces the special literature system realization example, summarizes so far work done, and the future research directions were also prospected.
