Management Information System Overview
Management Information System is that we often say that the MIS, is a human, computers and other information can be composed of the collection, transmission, storage, maintenance and use of the system, emphasizing the management, stressed that the modern information society In the increasingly popular. MIS is a new subject, it across a number of areas, such as scientific management and system science, operations research, statistics and computer science. In these subjects on the basis of formation of information-gathering and processing methods, thereby forming a vertical and horizontal weaving, and systems.
The 20th century, along with the vigorous development of the global economy, many economists have proposed a new management theory. In the 1950s, Simon made dependent on information management and decision-making ideas. Wiener published the same period of the control theory, that he is a management control process. 1958, Gail wrote: "The management will lower the cost of timely and accurate information to better control." During this period, accounting for the beginning of the computer, data processing in the term.
1970, Walter T. Kenova just to the management information system under a definition of the t
erm: "verbal or written form, at the right time to managers, staff and outside staff for the past, present, the projection of future Enterprise and its environment-related information 原文请腾讯3249114,^~.www.lwfree no application model, no mention of computer applications.
1985, management information systems, the founder of the University of Minnesota professor of management at the Gordon B. Davis to a management information system a more complete definition of "management information system is a computer hardware and software resources, manual operations, analysis, planning , Control and decision-making model and the database - System. It provides information to support enterprises or organizations of the operation, management and decision-making function. "Comprehensive definition of this
Explained that the goal of management information system, functions and composition, but also reflects the management information system at the time of level.
With the continuous improvement of science and technology, computer science increasingly mature, the computer has to be our study and work on the run along. Today, c
omputers are already very low price, performance, but great progress, and it was used in many areas, the computer was so popular mainly because of the following aspects: First, the computer can substitute for many of the complex Labor. Second, the computer can greatly enhance people's work efficiency. Third, the computer can save a lot of resources. Fourth, the computer can make sensitive documents more secure.
Computer application and popularization of economic and social life in various fields. So that the original old management methods are not suited now more and social development. Many people still remain in the previous manual. This greatly hindered the economic development of mankind. In recent years, with the University of sponsoring scale is growing, the number of students in the school also have increased, resulting in educational administration is the growing complexity of the heavy work, to spend a lot of manpower, material resources, and the existing management of student achievement levels are not high, People have been using the traditional method of document management student achievement, the management there are many shortcomings, such as: low efficiency, confidentiality of the poor, and Shijianyichang, will have a large number o
f documents and data, which is useful for finding, updating and maintaining Have brought a lot of difficulties. Such a mechanism has been unable to meet the development of the times, schools have become more and more day-to-day management of a bottleneck. In the information age this traditional management methods will inevitably be computer-based information management replaced.
As part of the computer application, the use of computers to students student performance information for management, with a manual management of the incomparable advantages for example: rapid retrieval, to find convenient, high reliability and large capacity storage, the confidentiality of good, long life, cost Low. These advantages can greatly improve student performance management students the efficiency of enterprises is also a scientific, standardized management, and an important condition for connecting the world. Therefore, the development of such a set of management software as it is very necessary thing.
Design ideas are all for the sake of users, the interface nice, clear and simple operation as far as possible, but also as a practical operating system a good fault-tolerant, the user can misuse a timely manner as possible are given a warning, so that users timely correction . T
o take full advantage of the functions of visual FoxPro, design powerful software at the same time, as much as possible to reduce the occupiers system resources.
Visual FoxPro the command structure and working methods:
Visual FoxPro was originally called FoxBASE, the U.S. Fox Software has introduced a database products, in the run on DOS, compatible with the abase family. Fox Software Microsoft acquisition, to be developed so that it can run on Windows, and changed its name to Visual FoxPro. Visual FoxPro is a powerful relational database rapid application development tool, the use of Visual FoxPro can create a desktop database applications, client / server applications and Web services component-based procedures, while also can use ActiveX controls or API function, and so on Ways to expand the functions of Visual FoxPro.1651First, work methods
