Information System exists in any organization. Generally speaking, the so-called information system refers to the information system composed of computer hardware Beijing website production , network and communication equipment, computer software, information resources, users, and rules and regulations constitute a human-computer integration system for the purpose of processing information flow, to acquire, store, process, and transfer data, information, and knowledge for the organization's operation, management, and decision-making, and to help the organization effectively achieve the goals set. Information system discipline is classified as management discipline in China. In CC2004, IS-2002 based undergraduate knowledge field is given, which is divided into three parts, covering information technology, organization and management, system theory and development discipline fields. Their composition is shown in Table 10-2. It can be seen that the information system specialty is actually the engineering implementation and system construction of "computer application field". The knowledge field of this discipline involves various application fields and industry businesses. The computer-based information system has always been a key part of the organization's products, services, operations and management. Efficient use of information systems is an important factor for organizations to gain and maintain competitive advantages and provide quality services. The information system supports the management process at all levels of operation, tactics and strategy. Information system plays a vital role in the process of finding problems, analyzing problems, making decisions and solving problems. Information system is also a professional direction of computer science and technology, which cultivates professionals who can effectively and conveniently obtain and use information by means of informatization, support enterprises and departments to operate efficiently, and participate in the planning, design, evaluation, implementation, operation and optimization of information systems. The problem space of information system discipline is shown in Figure 10-6. The professional direction of information system is obviously different from the other four professional directions of "computer science", "computer engineering", "software engineering" and "information technology". Its uniqueness lies in that it introduces the knowledge of the organization and its internal functional management in the "basic knowledge field" and "related knowledge field". Compared with the professional direction of computer science, information system is a professional direction with strong applicability and practicality. It does not emphasize deep and systematic mastery of basic computer theory, but it focuses on leadership, communication skills, and the ability to insight into organizational business processes, analyze organizational needs, propose organizational information system planning and evaluate information system solutions. Compared with computer engineering and software engineering, although they both emphasize the practical teaching link, there are differences in the nature and content of practice. The practical link of computer engineering and software engineering emphasizes the "manufacturing" or "development" of computer software and hardware; The practice of information systems emphasizes how to plan, evaluate, design, build, operate and upgrade information systems for various organizations. Compared with the information system direction, the information technology professional direction emphasizes technology, pays more attention to the construction, management, operation and maintenance of the physical and logical support system of the information organization carrier, and emphasizes the realization of system integration under given conditions and requirements to meet the requirements of selection, creation, application, integration The needs of computing management and other aspects. The information system major focuses on the organization and utilization, analysis and design of information, pays more attention to training students' management ability, team cooperation and communication ability to plan, build and operate information systems according to the organization's development strategy, and focuses on the effective acquisition and full use of information. The direction of information system specialty is also different from that of "information management and information system" specialty currently offered in Chinese universities. The school running subjects of the latter are respectively from the Business School, the School of Economics and Management and the School of Information. The training programs and curriculum systems of different colleges and universities have different priorities, some emphasize the mastery of functional management knowledge, and some emphasize information retrieval, information analysis and information services. In addition to emphasizing the balance of computer and management knowledge and the knowledge of information system construction methodology, the direction of information system specialty under computer science and technology has obvious advantages in computer technology, network technology, etc. Starting from two different basic disciplines, the "information system" of computer discipline More emphasis is placed on the technology of information system construction and information processing, and the "information system and information management" of management discipline emphasizes the management of organization information itself and the application oriented to organization business.
