College Reference Room Tao Bai, Yu Tian(B) , and Wuyungerile Li College of Computer Science, Inner Mongolia University, Hohhot 010021, China baitaotao@sina.com, tianyu@mail.imu.edu.cn Abstract In the current university reference room, there are some problems such as backward system facilities, simplistic manual management, and limited funds, resulting in the repeated purchase of scientific books, non-transparent reference information as well as the waste of funds, which reduced the staffs work effectiveness and decreased references circulation Taking Inner Mongolia University for example, we designed and developed a shared information management system for reference rooms This system uses web service and three-tier architecture to simplify the workflow of reference room administrators, changes the previous lack of manual processing mode, achieve the resource sharing for research funding books and so that it can save money, meanwhile, it provides a quick and convenient query service for teachers and students Keywords: Reference room Web service · Shared information management Introduction University college reference room is one of the important sources of information for teachers and postgraduates Due to the shortage of staff, the backward system facilities and the limited funds, the management of the most universities college reference rooms is still handled manual Such backward treatment not only increases the workload of the staff and reduces the efficiency, but also takes inconvenience to the borrower’s checking and borrowing, so that reduces the circulation of reference In order to make up for the lack of manual processing, we develop a college information room management system to achieve shared information management In this paper we present the analysis, design, and implementation process of the reference room management system Current Status of College Reference Room Management Take College of Computer Science for example, College of Computer Science of Inner Mongolia University was established in 1997, and the college reference c ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2018 S Liu et al (Eds.): eLEOT 2018, LNICST 243, pp 361–371, 2018 https://doi.org/10.1007/978-3-319-93719-9_49 362 T Bai et al room has kept abundant books in computer science and related fields, including computer application basis, discrete mathematics, Programming, network theory and development etc College has 55 kinds of Chinese periodicals and 13 kinds of foreign periodicals With the development of computer science in recent years, the college has undertaken more than 60 scientific research projects at the provincial and national level, including 50 projects funded by the National Natural Science Foundation of China, key projects under the Ministry of Education, projects under the Ministry of Industry and Information Technology Development Fund, key projects in Major autonomous regions These projects encourage teachers to spend large amounts of funds to purchase the necessary books and materials, and the books are targeted, practical and timeliness However, due to the outdated management, there are disadvantages of repeated book and material purchase, book and material information is not disclosed, and so that cannot share the resource Our library information management system provides eight management modules including user management, book management, periodical management and loan management etc., as well as six user modules such as reference inquiry and reference application, which realizes information management of information and satisfies user query, borrowing, application and other needs Meanwhile, it achieves generating report, uploading, downloading, collection, sharing, sending message, online retrieval and other features System Design and Implementation According to the actual needs of the reference room, all users are divided into two categories, including ordinary users, and administrators In addition to the needs of two types of users, reference rooms requirements should also be considered when developing the system The main needs of ordinary users are data query and borrow materials To meet this demand, the primary task of the system is to provide comprehensive and standardized reference and information Apart from the basic information, the system should provide information such as catalogs, profiles and other information to facilitate the borrowers’ search, reference and borrowing Second, in order to provide a better rental service, in addition to providing comprehensive information, the system should provide detailed loan information for each reference to inform users of the current borrower of the reference and the earliest return time of the reference Finally, the system should automatically generate borrowing log information according to the borrowing situation, and feed the borrowing log to the borrowers According to the characteristics of the reference room, users can also apply for information, the academic research purchased reference into archive reference The main requirement of the reference room manager is the management and maintenance of much information: such as books, magazines, loaning business and users The administrator needs to manage the above information conveniently and quickly through the system, and back up, update and maintain the information and report the information Because of the huge amount of information that is managed and maintained, Shared Information Management 363 the system should provide convenient and fast information entry functions For example, books, periodicals and other materials require a large amount of information to be entered However, such information can be obtained by querying the ISBN number or the ISSN number Therefore, this access to information and information interface to reduce the workload of the input reference Reference room construction needs are the most important; reference management system is different from library management system, reference management focus on the construction of the reference, which has a strong professional pertinence Therefore, the system of reference management and maintenance should be based on the actual situation of the college, according to their professional characteristics of reference classification 4.1 System Outline Design Module Design According to the characteristics of college reference room management and actual needs, the system is divided into
