1 1.2 LIMS Laboratory Information Management System
1.2.1 LIMS Overview
LIMS laboratory information management system so far has developed more than three decades, since the past ten years, the letter
Information technology, the rapid development of Internet technology, a variety of technology platforms for LIMS has played a significant role in promoting. current
The LIMS managed content is no longer a simple device management, personnel management, sample management, and print output report
Tables and other functions, with advances in software engineering technology and industry standards, coupled with Internet technology permeate all
Every corner of the industry, LIMS applications reached
One
In the past two decades to an unprecedented height.
The world's first
One
Generation LIMS in the late seventies appears, when the laboratories LIMS mostly in soft
Under pieces development services provider's technical support or rely on technical strength and technical personnel of the unit, according to the characteristics of this laboratory,
Customized
One
Sets management system does not have the characteristics of versatility. Because the technical capacity, funding and other issues, which
Kind of management system with a multi-function, and system upgrade maintenance difficulties, poor flexibility of the situation. Later, with the open system
Made into commercial development, the original LIMS gradually disappear from the organizations and enterprises, and domestic and international level since
Differences in philosophy and a big gap, commercial LIMS development has not been widely supported and recognized
[2]。
Commercial LIMS, the second generation appeared in the eighties, this type of system is based on client / server architecture,
It solves the first
One
Generation LIMS exist many problems. For example, users can realize the majority of demand for laboratory
Support changes, system upgrades and maintenance simple and convenient system utilization is improved. However, there are still
One
More difficult to reconcile the conflict, such as commercial LIMS system is universal, it is necessary after the installation of the system
Customization of functionality, the special needs of each laboratory to increase the coding, which requires programmers at the same time to take into account
LIMS system administrator. Nature of the laboratory are diverse, many computer programmers are born free
Law to understand the operation mechanism of biological laboratories, which brought difficulties to the coding system. Further, a computer program is provided
Total staff mobility is very large, frequent system maintenance programmers because it was designed like the departure of a standstill
state. For these reasons, no professional computer staff can manage and maintain the largest LIMS needs
begging.
The late nineties there have been third-generation LIMS based on C / S architecture of the last century, the system needs to further increase user
Any code or program. After the system is installed in accordance with the actual requirements of users only simple configuration ready for use. laboratory
User during use, understand basic Windows operations, you can perform simple training posts, and press
Changes accordingly as laboratory setting.
In 2004, the fourth generation of Internet-based technology LIMS appear to meet the many companies and organizations not only
Limited local area network requirements. The fourth-generation LIMS is characterized by
[3]：
1) based on browser / server architecture of B / S, it can be easily configured WAN Internet and corporate Intranet
on. B / S structure of the advantages is that the client simply needed to install the system browser, without installing large and complex client software
Pieces of the system, system management is server-side management. As long as the server's load capacity is sufficient, the number of customers can not

The system increases. System upgrades, data sharing, database management very convenient.
2) In the Internet environment, it can be distributed to laboratories around the connection

body.
3) Users can connect with the laboratory using real-time via the Internet, there is no geographical constraints and space.
4) by the WAP Wireless Application Protocol, for easy access to real-time control of wireless mobile devices laboratory
Information.
1.2.2 Computer Laboratory Management
Computer Lab domestic colleges and universities as a student in-depth understanding of the theoretical knowledge learned in the classroom, can improve problem solving
Force, hands-on training habits, rich brain is an important place. With the university teaching methods, teaching methods
Improvement and consider the actual situation of student learning, take a lot of computer lab open to students. Open Laboratory
Management content and daily laboratory work than administrative burden is much heavier. Laboratory established in line with the characteristics of the tube
Management systems become practical solutions
[4]。
Computer Laboratory Management consists of two main elements: teaching and laboratory management information platform for environmental management.
Teaching Information Platform mandate to increase the quality of teaching and experimental level tasks, information technology, network teaching information that each
Key content information management of college, not only provides efficient experimental test management tools and information for teachers experiment
Nuclear, electronic information management, but also provides students with the best platform to integrate theory with practice and teaching resources to enable the students
Data sharing and exchange of experiences between, the students of divergent thinking and innovation provide useful help. Laboratory environment
Management, including students in attendance, computer lab device management and access control management. But also to test out
All the staff room provides query capabilities, to provide remote maintenance management system to facilitate system administrators to effectively manage the system.
Figure 1.1.
Computer Laboratory Management System Main functions are as follows:
1, system maintenance
Computer Laboratory Management System
Laboratory information management platform for teaching environmental management
The integrity and reliability of data protection systems, system integration by the system administrator privileges

Allocation and management. All religions
Each unit is set to increase school administrators to manage system users to modify and delete permissions settings. The system administrator through the campus
Network do the daily management of the system software and laboratory equipment information, and laboratory management IC card access control system

Data collection
And authorization for a variety of statistics and query output print
[5]。
2, time and attendance and access control
Access control and attendance management centrally managed through the issuance of IC card on campus, into the open laboratory personnel
IC card in the card reader into the lab and enter the password, the system automatically collects data storage for attendance and raise queries
Support for data and periodically transmit data to the server. System administrators IC card system

According to the cardholder and management body
Different parts assign different privileges.
3, comprehensive inquiry
The multi-stage system administrator roles are set by the user queries, fuzzy queries in the system and can be set
Conditions comprehensive inquiry. A variety of data on individual query execution statistics and summary statistics can be for teachers, students, administrators
Personnel, laboratory equipment and so on according to the time of execution statistics even date statistics, can also be formed in accordance with a single class, department
Bit summary statistical reports, and the results printout.
4, information dissemination
The system can be published in the relevant platform developed in the laboratory, teachers teaching, publishing resources, laboratories and other usage
Kinds of information to facilitate students and teachers inquire about effective personal time schedule
