(1) The transaction processing system (TPS) is mainly used to support the daily activities of operators. Mainly responsible for handling daily affairs.
(2) The management information system (MIS) needs to include the transaction processing system within the organization, providing comprehensive internal data and general and large-scale external data. The information provided by many tactical layers can be provided in a familiar and favorite form as the managers of this layer hope. However, it is impossible to determine in advance another part of the information for tactical managers and most of the information for strategy manager. These uncertainties are a great challenge to the designers of management information systems.
(3) Decision Support System (DSS) can get information from management information system to help managers make good decisions. The system is an analysis program, which deals with data summary and speculation to support managers to make decisions. It is an interactive information system based on computer, which combines the analysis and decision-making model, the information in management information system and the speculation of decision makers to achieve good decision-making effect.
Question 2: What characteristics should a complete office information system have? Personnel management, schedule management, document management, message management, system management, attendance management, etc. The best thing to do in this respect is Zhiyuan Software, which has ranked first in the market share for ten consecutive years.
Question 3: What are the main features of management information system? The contents of the 360 encyclopedia entry "Information Management System" are reproduced for your reference!
A perfect management information system (MIS) has the following four standards: clear information requirements, information that can be collected and processed, information provided to managers through programs, and manageable information.
Unified planning database is an important symbol of the maturity of management information system, which indicates that management information system is the product of software engineering. Information appreciation is realized by MIS, and data are statistically analyzed by mathematical model to realize auxiliary decision. MIS develops and changes, and MIS has a life cycle.
The development of management information system must have a certain scientific management foundation. Only on the basis of reasonable management system, perfect rules and regulations, stable production order, scientific management methods and accurate original data can the development of MIS be carried out. Therefore, in order to meet the needs of MIS development, enterprise management must gradually improve the following work: (1) Management work is programmed, and all departments have corresponding operation processes; The standardization of management business, each department has corresponding operating norms; Unified report documents, fixed content, time limit and format; Perfection and coding of data.
Question 4: What are the characteristics of excellent IT information system management software? Successful case of enterprise management consulting An excellent and suitable software should include the following characteristics: First, it is the business characteristics and functions supported by the system. In other words, the functions provided by the system should be comprehensive and powerful, targeted to a certain extent, and fully meet the needs of existing business applications of enterprises. Second, the ease of use of the system. This means a friendly interface, easy to learn and use; Use the function to see online help; Have applied for a fast track; Personalized functional interface and menu options can be customized according to work characteristics and preferences; Graphical presentation of business processes and system functions to guide operators to operate smoothly and quickly; Business data information can be linked according to business logic characteristics and attention. The third is the stability and high availability of the system. That is to say, whether the system can feed back the application request to users in time for a long time and stably. It mainly includes: whether it is developed based on a mature platform; Whether it has been tested by hundreds of actual customer applications; Whether it can give customers a uniform response in operation, and whether the response speed will decrease or collapse when the number of users reaches a certain amount; Will there be data loss? Whether there are protective measures to prevent data from being damaged due to misoperation; Whether the data input by the customer is legal or not. Fourthly, it is the applicability and flexibility of the system. Usually, the architecture of system technology determines whether the system is applicable and flexible. It mainly includes: whether the business process and input and output forms of the system can be customized, report format and report output file format; Whether query conditions, related calculation formulas and data sources can be customized; Whether the fields in the system data table can be customized and reconstructed; Can you support the diversity of clients, so as to meet the personalized needs of different industries and enterprises without programming, as well as the application needs of new business or business transformation in the future? Fifth, it is the expansibility of the system. That is, whether the system is easy to expand or integrate with other systems (an enterprise always has multiple systems, and the business of the enterprise is related, so it is objectively necessary to integrate the systems).
Question 5: What is a management information system and what are its characteristics? Management information system (MIS) is a human-centered system that uses computer hardware, software, network communication equipment and other office equipment to collect, transmit, process, store, update, expand and maintain information.
Management information system (MIS) is a new discipline, and its definition is as follows.
Structure principle of management information system
The progress of computer technology and communication technology is also constantly updated. At present, it is generally believed that MIS is a system for managing information, which is composed of people, computer equipment or other information processing means. [2]
Management information consists of six aspects: information collection, information transmission, information storage, information processing, information maintenance and information utilization. A perfect management information system (MIS) has the following four standards: clear information demand, information acquisition and processing, providing information for managers through procedures and management information. Unified planning database is an important symbol of the maturity of management information system, which indicates that management information system is the product of software engineering. Management Information System (MIS) is an interdisciplinary comprehensive subject, which is composed of computer disciplines (network communication, database, computer language, etc.). ), mathematics (statistics, operational research, linear programming, etc. ), management, simulation and other disciplines. Information is an extremely important resource in management. The success or failure of management depends on whether effective decisions can be made, and the correctness of decisions depends largely on the quality of information. Therefore, whether information can be effectively managed has become the primary problem faced by enterprises. In the modern society that emphasizes management and information, management information systems are becoming more and more popular.
Features:
1. Data processing function
2. Planning function
According to the existing conditions and restrictions, provide the plans of various functional departments. Such as production plan, financial plan, procurement plan, etc. And provide corresponding planning reports according to different management levels. [2]
3. Control function
According to the data provided by various functional departments, supervise and inspect the implementation of the plan, compare the differences between the implementation and the plan, analyze the differences and the reasons for the differences, and assist the management personnel to control them in time. [2]
4. Prediction function
Use modern mathematical methods, statistical methods or simulation methods to predict the future according to the existing data. [2]
5. Auxiliary decision-making function
Using the corresponding mathematical model, the optimal solution and satisfactory solution of related problems are deduced from a large number of data to assist managers in decision-making. In order to make rational use of resources and obtain greater economic benefits.
Question 6: What are the characteristics of information technology? Information technology is sensing technology, communication technology, computer technology and control technology. Maybe you are not satisfied with this definition, but it is a concise, concrete, systematic and practical definition. Sensing technology is the technology of obtaining information, communication technology is the technology of transmitting information, computer technology is the technology of processing information, and control technology is the technology of using information. Therefore, this definition not only gives the content of information technology, but also clarifies the system of acquisition-transmission-processing-utilization of information technology, and also clarifies the functions and relationships of sensing, communication, computer and control technologies with clear concepts, clear fields and public perceptual knowledge in information systems.
Although the four technologies of sensing, communication, computer and control have their own functions in the information system, they are mutually contained, intersected and integrated in terms of technical elements. Sensing, communication and computer are inseparable from control; Sensing, computer and control are also inseparable from communication; Sensing, communication and control are inseparable from computers.
In addition, from the current situation, the functions of sensing, communication, computer and control are not at the same level, and computer technology is in a relatively basic and core position compared with the other three. Because it is the rapid development of computer technology that drives the rapid development of the whole information technology. In fact, before computer technology came into being, sensing technology, communication technology and control technology had already come into being. But at that time, these technical levels were still relatively low, and many operations needed to be carried out manually. Since the emergence of computer technology, the level of sensing technology, communication technology and control technology has been greatly improved. Not only the level of automation can't be compared with the past, but also the functions and services that are more and more powerful, more complex, more convenient and more efficient are realized through program control. It can be said that the basic feature of current information technology is computer program control.
The advantages of program control are: first, it can run reliably for a long time. Because once the program is designed correctly, it can be executed repeatedly once and for all to complete the specified function or service, and its reliability far exceeds that of manual work. Second, technology has made rapid progress. Any complex and powerful program is composed of many simple and single-function programs. The continuous development of programs will naturally accumulate, and the accumulation of programs will directly bring about technological progress. Moreover, technical updates are often only software updates, and the cost is lower. Third, it is convenient to build large-scale systems. Large-scale systems can be divided into many subsystems, which are controlled by internal programs and connected and coordinated by data or protocols. In this way, it is not difficult to establish a large-scale information system covering the whole world.
It is precisely because of these advantages that information technology has made rapid progress since the emergence of computer technology. Its application has penetrated into all walks of life and every corner of society, greatly improving the level of social productivity and bringing unprecedented convenience and benefits to people's work, study and life.
Although today's information technology has brought unexpected benefits to people, the pace of technological progress will not stop. In the technological transformation facing 2 1 century, the development direction of information technology will be intelligence.
Today's information technology has surpassed the human brain's ability in information processing in some aspects, such as memory ability, computing ability and so on; But it is not as good as human brain in many aspects, such as character recognition, speech recognition, fuzzy judgment, fuzzy reasoning and so on. More importantly, the human brain can continuously improve its information processing ability through self-learning, self-organization and self-adaptation. All the capabilities of the stored program computer are given to it by people through programming. It is mechanical and rigid, and cannot improve itself compared with the human brain.
In view of the above problems, people began to study the theory and technology of intelligence many years ago, and explored the mechanism of human brain information processing in order to better simulate the function of human brain with machines. After decades of efforts, the theory and technology of intelligence have made great progress. It is these advances that provide the foundation for the intelligentization of information technology.
Good luck!
