1. Title: JAVA-based laboratory management system
2, Keywords: laboratory management, structural analysis, then, the management system
3, needs analysis
With the deepening of computer applications, almost all walks of life are closely linked with the computer, people's lives have been inseparable from the computer. In particular, some enterprises and institutions, in order to meet the needs of modern development, and improving the management and office efficiency, are the fastest computer was introduced, many enterprises have this unit connected to a computer network, which greatly to speed up the work efficiency of enterprises, improve the speed of information transfer.
For a long time, laboratory equipment management mostly remain on paper medium, because of past exam-oriented education determines the experimental course of the past remain in the top going through the motions, so the management of laboratory equipment are not many, the traditional method can cope, with the development of the times, the lab has become a student of the master class, the instrument equipment rapid increase in the number of laboratories, number of sections of the laboratory classes are growing, the teachers of the loan facility equipment, the number of return the frequent damage to equipment and instruments, and many other content management is not the traditional method capable of
managing the process of school laboratory, found some problems. Which as: In the experimental course on the overall arrangement of each class
needs to implement between artificial and often occur because the second batch experiments conflicts transfer courses, but the need for timely notification trouble classroom teachers and class officers. Therefore, in order to facilitate the management of the engine room, we propose solutions use the Internet to manage the laboratory, in order to suit the network lab management system for the management of application background, developed - a web-based laboratory management system,
therefore, the development of such a set of management software has become very necessary thing, it can be specific, the rationalization of laboratory equipment and related management information, with a structured way of thinking to understand how computers work.
4, the main function of the laboratory management:
(1) Laboratory Information: Application Laboratory, the application laboratory compartment, a list of laboratories, laboratory information inquiries.
(2) Laboratory Information Management: Adding new devices (equipment list), add talent (talent list), (add appropriation), add paper books (academic papers list), add the award-winning (winning list), add a patent (patent list).
(3) My Tools: Modify password.
5, B / S architecture introduces
B / S (Browser / Server) structure is the structure of the browser and the server. It is with the rise of Internet technology and
C / S Structure - kind of structure changes or improvements. In this structure, the user interface is implemented by www browser. Very small part of the business logic implemented in the front end (Browser), the main business logic on the server side (Server), a so-called three 3-tier structure. This greatly simplifies the client computer load, reducing the cost and system maintenance and upgrade work
, reducing the total cost of ownership (TC0). Look at the current technology, local area networking applications B / S structure, and by database applications on Internet / Intranet mode, relatively easy to grasp, the cost is lower. B / S structure - - secondary
place development, to achieve different people from different locations to different access (over LAN, WAN, Internet / Intranet, etc.) access and common database operations; it can effectively protect data and access management platform, the database server is also very safe. Especially after the cross-platform JAVA language such appearance, B / S architecture management software is more convenient, fast, and efficient.
B / S structure is the use of a maturing www browser technology, combined with a variety of browsers Script languages (VBScript, JavaScript-- and ActiveX technology, with a universal browser implements powerful original need special software to achieve the complex function, and save development costs, is a new software system construction technology, the architecture of choice for today's applications in the network topology, B / S structure using star establish internal communications network using the Internet or virtual private network (VPN). have to save investment, broad cross-regional advantages.
