Key words： automatic office、information service、 information safety
With the development of computer technology and Internet technology, has been widely used in computer networks. For colleges and universities, to establish a campus network in the following two aspects : First, the general role of external links realize with the Internet and provide the university's information services into the world of information trends. understanding of the outside world. strengthen academic exchanges and cooperation. Another is the establishment of the university's management information systems, management of scientific modernization; use modern means to improve the quality of teaching and management standards. Through the network, the use of multimedia and communication technologies to achieve long-distance teaching, teaching achieve complementarity. With the relatively sound management information systems, networks, the start of construction of the campus network can fully realize the importance and effectiveness. Therefore, what technology is the development of management information systems college this study.
1 Higher Education Management Information System
Domestic demand and target college campuses network development is uneven. information systems to coexist in three models. Single management model is the first model in some schools, the computer network has yet to be established. not for data exchange between computer and information sharing. They remain in the business sector-oriented individual level, This determines their data systems often inconsistent, prone to data loss, system infection and other problems; The second model is the LAN management model, they can conduct work on the network. For example, the establishment of a management information system on LAN, the data in departmental servers. the management and staff to provide information-sharing, such an approach for the management of the department has played a catalytic role solve the internal problems of data redundancy and inconsistency, but to complete the application software on the workstation. Workstation burdens are too heavy, the server is only document storage, data storage and printer sharing, network utilization lower. Many schools have their own local area networks, each going its own way and make it impossible to share data between the different units. achieved more rational flow of information resources; The third model is the school campus online information system The information management system as the foundation of the system. In addition to satisfying the internal management of the use of data, can also provide information services to other departments or school staff. Higher Education Management Information System is faced with the following needs : to strengthen the scientific and technological information between domestic and foreign schools. The principal sectors of business information systems sector, to clear the channels on the basis of information between departments, establishment of the school shared database; replace the traditional manual backward office, the support of modern office environment. improve office efficiency. Web-based online network teaching system, using the Internet as the medium of campus media, content delivery, implementation of online teaching on campus, teaching management, and online testing and the Internet.
2 Information System of Higher Education
Based on the analysis of Colleges and Schools information needs can be drawn : information services, Teaching Information office of information and information management. These are decisions of the College is a school-wide information system, an open, distributed, multimedia information system According to the information needs of the information subsystem in schools, information services, office automation, Teaching and network administration and management information systems. These subsystems scope of the different users, different ways of organizing data, it requires a different technique to solve. Oriented to the domestic, internal and external users of the system, users www most convenient; management functions in the most information-structured data, users of the data have complicated the operation, Database management should be mainly in the flow of information among various offices, mostly unstructured data, also complicated process information using Lotus Notes data organization.
2.1
WWW technology with the development of an integrated information service system
The emergence of Internet, WWW technology to the mainstream of the rapid development of information systems, using Web technology. break the existing information services, in addition to the information-oriented school campus services, but also the nation and even the world as a whole. Integrated information system to the physical environment of campus networks, Internet connected with the outside. The type of information provided is varied. In addition to daily use of the information on the type of textual information, it can also provide audio, Video appears in the form of services and information, such as school leader's important speech recording, a wide range of academic, Students can mold the sentiment of music and video content is very rich information. WWW integrated information system to provide various multimedia services, also achieved with departmental level management information system (RDBMS) and the school office automation system (NOTES) organically combined. Information from the type of service extended to the SQL Server database and file system Notes database. Due to the breadth of information users of the system determine that the client must use a common cross-platform software. Browser provides a good system for information services, The system / (Browser), the architecture is easy to operate, Client software installation simple and easy maintenance. Comprehensive information service system in the multi-campus Internet Information Server component. Taiwan is one of many user-oriented information servers Other servers can be designated special port users direct access but also from the information server connectivity, through the main server for a visit.
2.2 Technology campus network using Notes office automation system
Universities in the management, the mobile office information in two ways, one is the flow of information between the upper and lower levels. If the Department's Office issued a notice to the principal's office, the Office of the Department issued a notice to give teachers and students; Another is the horizontal flow of information. If Dean's Office for Personnel Management Information, Personnel Services Department to research information. To improve office efficiency, we must act to change the traditional manual method, the application of modern office technology and to establish the office system. Office System is built on the campus of the online information system geared to a wide range of users. It used Lotus Notes as a development platform. Notes database with advanced document processing functions will be capable of handling structured data. Documents can also deal with the general data, graphics, image, voice and other unstructured data. users familiar with the software, such as MS Word, MS Excel integration. The function of the office system leaves plenty of room for further expansion. Has been developed document management, e-mail, conference management, office discussion zone. documents and other general office operations and information dissemination functions. Notes is due to the dissemination of information on WWW function Notes technology development office to the school system not only for office use. and the school's teachers and students can use the system processor office visit.

2.3 database administration and management information systems technology   development

To establish a campus network to the physical environment of the various functional departments of management information systems, all administrative departments to support specific operations, the school teachers have the basic data, students, research, financial assets and equipment information, which are scattered in various sectors of the original PC or LAN servers departments, Campus networks have been established in the future, in order to achieve all the schools to share information based on the need to focus on data storage. unified management. To enable multi-level user-oriented information system service Management Information System and W (Browser /WebServer/DBMS) combined structure. W MIS structure is a widely used form use a unified client browser as a platform for client-side software development significantly reduce the workload; Because all the information stored in the application server, the system is very easy to maintain, and upgrade. Therefore the development of information systems in schools, the structure of the function of all W can be used to adopt this approach. W using the structure, We should try to avoid Web server and database server at the same messages. Such an approach would increase the burden on the server, when simultaneous visits to a number of users, Web prone to bottlenecks systems paralyzed. In the Educational Management System, the development of class selection system using W, As students in a campus computer on the network can be conducted Course Selection. Web server can not restrict the number of simultaneous visit. At least several hundred computers at the same time, the campus Internet access Course Selection server, a Web server is difficult to handle, it is necessary to open up a number of services from multiple server port can be resolved. W Despite the many advantages, but also in the development of technical means for the rich enough, Under the complicated operation in the data, still using the , This approach requires more physical location in the computer unit concentration in a limited number of areas have no control over. What methods and functions of two types of users need to determine, geographical dispersion of users must use W structures, such as students, teachers Information, As they scattered and uncertain position that the use of WWW interface optimization; departments and agencies to the Office of General WWW based interface; In the Senate sector (shoulder registration results Course Scheduling. Course Selection handle such matters), which mainly in the data processing sector, concentrated and complex data processing. consider ways.

3 Higher Education Management Information System Security Strategy

Campus Network and Management Information System is completed, anyone can visit college campuses through computer networks. which might be "hackers" tried to attack networks, network sabotage, computer viruses spread, Others may steal confidential technical information and data, etc., it is particularly important to safety management. The main management information system and network security, including physical security and logical security; Physical security refers mainly to the maintenance and use of network hardware and management; logical security from the perspective of the software. mainly refers to data confidentiality, integrity, availability and so on. Since the colleges and departments of the office information system to support school activities, centralized storage, and management of data, These information security. To ensure the security of information sharing, security and data management systems management from the two aspects of security to be guaranteed. Security in data management, input data to test the efficiency of the establishment of a sound data backup and archiving system. System administrators responsible for the system, the key management systems and procedures in the server room management system; safety management systems in multi-layer security mechanism that information server network security, operating system security. Database security in the application layer security and security assurances. Information in the network security server, server to protect the information resources information servers and install a firewall connected to the campus network, and the frequent use of a firewall to prevent unauthorized users download. guess system passwords on the server for the open port limit, which allows the user to visit the port, restrict user access port IP addresses; in the operating system security, system administrators strictly control the power of users, Some users have conducted some operations in the designated machine; Database security of the user access control list doing database audit and inspection records. Campus network security management and management information systems is a major problem, only a good emphasis on safety management, adopt good management practices to ensure the campus network and the normal operation of management information systems.
