Design and Implement of University Laboratory Equipment Network Management Platform Based on C/S and B/S Model
Abstract:
Lacking management of laboratory equipment in university currently, a strategy was proposed to manage laboratory equipment with network method by using software architecture based on C/S and B/S model. Network management platform for experimental equipment is a management system, which is also a complex monitoring system. For different users, being designed by reasonable software architecture, it will make better prospects for the system. This paper presents a framework of laboratory equipment management system of hybrid system, which includes the realization of main function, architecture, database design and implementation.
SECTION I.
Introduction
Laboratory is an important part in management of university that cannot be ignored. With the exoteric laboratory, teaching, research workload and increased foreign exchange, information-sharing of devices and systematic management are required urgently in university In the traditional way, information processing of equipment management in university is carried out manually. In this way, it is not only waste paper, but also require many human resources. Most device management software currently in use are single-user mode, but disadvantages that data cannot be shared and management is non-transparent and difficult to monitor. C/S(Client/Server) application structure can not only achieve the share of database resources, but also improve the security of the database. This structure model is a multi-user application development model, in which a server can provide services for multiple clients at the same time. Server is responsible for management of system resources effectively; Client accomplishes the task that interacts with users and data According to the command, service area executes corresponding data operation, which only returns final results to the user; thus, the amount of data transmission on the network could be reduced and performance of the system could be improved. By this way, C/S structure is very suitable for the need of equipment management system. At the same time, B/S (Browser/Server) model changes Fat-Client/Thin-Server structure of C/S into Thin-Client/Fat-Server structure, and unified browser software is the only software needed to be installed at client. Besides, because its based on TCP/IP protocol and HTTP protocol, cross-platform issues could be solved perfectly and each operating system could compatible well on different models. In sum, at one hand, C/S model structure has a strong management capacity, which is suitable for fast information processing in intranet system; on the other hand, B/S model have a good network scalability and compatibility. In terms of the management of laboratory equipment in university, because laboratory equipment of each college is stored in scattered locations, the use of hybrid structures(C/S and B/S) can ensure the relative safety of internal database. By highly interactive with internal users, its functions can meet the requirements of quick response of data query and amendment.
SECTION II.
System Design
A. System Architecture Design
Having analysed and researched management mode of each device management department, we decided to establish production management information system of laboratory equipment by taking into account actual demand of manager and user of device. Whole system could be divided into two sections: MIS can be realized by C/S model structure in intra-net of university and applications on Web server apply B/S model structure, by which users can make an appointment of experimental equipment through Internet. Database server stores all information and data which relates to equipment management. Web server is an interface for network users accessing database server which is an execution platform of web applications. Network topology of the whole system is shown in Fig. 1:
