Use what you ve learned to talk about your knowledge of information systems development and your own

Summary. Hello dear, are the characteristics of information useful for information system development? Why?

From the perspective of the characteristics of information system development, the development of information system is an extremely complex system engineering, with a long cycle, large investment and high risk, which is more difficult and complex than general technical engineering. The development of information systems involves computer science and technology, data communication and network technology, artificial intelligence technology, and various decision-making methods. The development process itself is a social process, and the factors that affect the success or failure of information system development include systems, policies, regulations, concepts, technologies, and so on.

Therefore, information system development is by no means different from the relatively simple network construction, database design, and hardware engineering!

Hello dear, are the characteristics of information useful for information system development? Why do you mean unbridledness?

Whether the management information system can be developed and used well is closely related to human behavior. For example, if the management personnel are unwilling to use the information system, or the leaders of the unit do not pay attention to it, do not actively lead the development and application of the system, do not seriously publicize and organize the staff school and the use of the management information system, or the developers and managers can not accept and closely cooperate with the development together.

Then, even if the management information system is technically very strong, it is difficult to run well. When managers are worried that their work may be replaced by computers after using computers, they often have negative confrontational feelings, such as proposing that the developed software system is not easy to use, it is better to deal with it manually, or they do not cooperate well and do not enter data in time. The management information system is a system that combines man and machine, and if man and machine do not cooperate, it is obviously difficult to run well.

The strategic and tactical thinking of information system managers in management directly affects the establishment, development, updating, management, and maintenance of information systems. That is why often a set of information systems does not re-select managers.

The five basic functions of an information system: input, storage, processing, output, and control.

Input function: The input function of the information system is determined by the purpose to be achieved by the system and the capabilities of the system and the permission of the information environment.

Storage function: Storage function refers to the ability of the system to store various information materials and data.

Processing function: Data processing tools: Online analysis and processing (OLAP) and data mining (DM) technology based on the warehouse technology of the digital circle.

Output function: The various functions of the information system are designed to ensure the optimal output function in the end.

Control function: control and manage the various information processing equipment that constitutes the system, and control the entire information processing, processing, transmission, output and other links through various programs.

Information system is a man-machine integrated system composed of computer hardware, network and communication equipment, computer software, information resources, information users and rules and regulations for the purpose of processing information flow.

From the perspective of the development and system characteristics of information systems, it can be divided into five types: data processing system, management information system, decision support system, expert system and virtual office.

Data Processing System (DPS).

Management Information System (MIS).

Decision Support System (DSS).

Expert systems: A subset of artificial intelligence (AI).

Office Automation & Virtual Office (OA).

The management hierarchy can be divided into two levels: manager information system, marketing information system, manufacturing information system, financial information system, human resources information system, and information resource information system. This is a logical MIS rather than a physical MIS, also known as an organizational information system.

Summary. 1.Structured Life Cycle Approach:

The establishment of a system is regarded as the growth process of a species of life. It consists of 6 development stages: system definition - requirement analysis - > system design - > writing ** - > installation and commissioning - > system maintenance.

2.Rapid Prototyping Method:

Quickly create a beta version of the management information system (which can be used for demonstration and evaluation), use this beta version to explore the needs of users, and then modify and enhance the basic version of this version. It consists of 4 development phases: Identification of basic requirements - Development of a prototype system - > Modification of the enhanced prototype using the prototype system.

According to a certain information system you have used, explain the advantages and disadvantages of the information system, and explain how to change the information system from the aspects of new information technology, management methods, processes, etc.

First, the goal of enterprise financial management is moving towards multiplicity.

In the old economic era, the ownership of enterprises belonged to the owners of equity capital, that is, all shareholders. The goal of corporate financial management is to maximize the wealth of shareholders, and employees are compensated for their labor in the form of wages. Enterprises in the new economic era pay attention to the principle of people-oriented, and the goal should not exclude the interests of employees.

Enterprises must rely on the innovative labor of employees in order to survive and develop. The labor of employees is no longer based on repeatable labor as in the industrial economy and society, so enterprises in the new era must also include "maximizing the interests of employees" into their goals.

At the same time, for the group that has a close relationship with the enterprise, such as creditors, customers, businessmen, the public, potential investors, and strategic partners, to meet the interests of these groups, it is also an integral part of the goal, which is to take cost efficiency as the guiding principle, and its purpose is to maintain the good reputation of the enterprise, or to obtain a business license, etc., and ultimately achieve a higher return on investment for the enterprise.

The goal of enterprise financial management in the new era is not the development of the goals of the industrial economy, rather than the total negation of the original goals, the goal is diversified, and the win-win goal is finally achieved.
