1 design principle of computer information management system
1. 1 Selection basis of programming language
According to relevant surveys, when developing system software, if computer programmers have a solid foundation, C++ is often the first choice in language selection. However, smarter programmers often don't choose this language, because although c++ has good integrity and can achieve high efficiency, it is difficult to learn and use flexibly. At the same time, due to the slow update speed of c++, some programmers will choose other programming languages. At present, the modes of computer information system are: foreground program and background database. Operating the background database through the foreground program must go through the data engine. According to the investigation, VB, PB and Delphi are the programming languages that can provide users with relatively perfect data interfaces at present. Compared with these three programming languages, C++ is obviously at a disadvantage in this respect. Therefore, it is more appropriate to design a computer information management system with these three programming languages. The system not only runs fast, but also is easy to maintain. If developing Windows system, c++ is often more suitable.
1.2 design principles of computer information management system
When designing a computer information management system, it is often divided into several independent areas or modules, and each module has its own independent function. The quality and independence of module division are often evaluated by "cohesion" and "coupling". "Coupling" is a technical term used to express the independence of each module of computer information management system. Coupling includes illegal coupling, data coupling and control coupling, and data coupling is the best coupling mode. Cohesion is mainly an index to measure the integration degree of each module's own components. Cohesion includes logical cohesion, coincidence cohesion and process cohesion.
Generally speaking, the division of computer information management system modules must follow certain standards. The most scientific module division method should be based on the strength of module combination, and strive to be independent of each other and not interfere with each other, so as to ensure that the interface between modules is simple and clear. To put it simply, it is necessary to design a computer information management system according to the design principle of "big cohesion and small coupling". The design of high cohesion and low coupling module is shown in figure 1.
Design principle of 1.3 module
When designing the module structure of computer information management system, it is necessary to refer to the characteristics of modules in independent subsystems and describe the module structure in detail to ensure that the follow-up work is more clear and reliable. Therefore, when designing modules, we must fully consider how to set the purpose and configuration of data transmission between modules and subsystems. In addition, programmers should also pay attention to some problems in module design, such as how to output and save the module structure diagram from the data flow diagram, actively explore similar problems and find solutions to promote the design efficiency of computer information management system.
2 computer information management system design method
2. 1 prototype design method
Prototype design method is a method with short design time, quick effect and convenient information exchange. This method mainly refers to the user's needs, uses the system rapid development tool in the design, constructs the system model, and then realizes the communication with the user on the basis of this model, and finally meets the user's needs. When designing a computer information management system with this method, it includes system preliminary design, system requirement description, system test, system debugging and so on. In the stage of system preliminary design and system explanation, users need to participate, and system designers can obtain basic demand data, and then make corresponding application systems quickly with the help of relevant development tools.
2.2 Periodic design method
Periodic method belongs to a design method of management information system, which is mainly composed of structured system analysis and design. The principle of this design method is to divide the life cycle of the system into different stages, such as system analysis, system detection and system transformation. Then, according to the needs and processes of relevant personnel, with the help of corresponding icon tools and working methods of the system, information documents are made, and then the management information system is designed in a structured and modular way. When designing an information management system with periodic design method, the whole system is usually regarded as a large module, and then the large module is decomposed and combined according to the specific needs of system analysis. When designing a computer information management system, the periodic design method has some characteristics: First, the development idea is clear. The development goal of developing a system by periodic design method is "user-oriented", which ensures effective communication with users in the whole process of system development, and then achieves * * * understanding in design. Secondly, stylized design works. Usually, the work content of each stage must be clear in order to control the system design process.
When the phased design task is completed, it is necessary to re-examine the design according to the work requirements and objectives set at this stage, so as to eliminate possible safety hazards in time and ensure the normal follow-up work. In addition, standardize the design of working documents. In order to make the working documents of computer information management design standardized, certain requirements are put forward for programmers. Programmers must complete the related documents, reports and icons in accordance with the relevant requirements whenever they complete a design task in a cycle method, so as to effectively connect the work in each stage and effectively monitor and maintain the working process of the system. Finally, the structural design method.
When designing a computer information management system by periodic method, it is necessary to ensure that each subsystem is independent and does not interfere with each other, so as to ensure the efficient analysis, design and maintenance process of the computer information management system. In addition, in order to improve the design efficiency of computer information management system as much as possible, we should choose other modes such as cooperative development or purchase of ready-made software in combination with the difficulty of system design, human resources and financial situation.
2.3 Comprehensive design method
The so-called comprehensive design method is to use the cycle method and prototype method in the design of computer information management system and combine them effectively. In general, when comprehensive design method is adopted, the design idea of circular method can be used to improve the design effect. The preliminary design of the system and the design of the analysis management system adopt the prototype design method, and then communicate with the users about the design. After reaching the understanding of * * *, the next step is to adopt the structured life cycle method. Through investigation and study, it is known that the comprehensive design method has the same characteristics as the two design methods, which not only can control the design process well, but also has a short development cycle and quick results. Therefore, when designing business information management system software, we can consider using comprehensive design method according to the actual situation, which not only embodies the flexibility in the design process, but also achieves better design results.
With the continuous development of information technology, computer information management system is more and more widely used in enterprise management, which even determines the quality of enterprise development and is related to the survival of enterprises. At the same time, the design method of computer information management system is constantly developing and perfecting, from the earliest periodic design method to the later prototype design method, and then to the comprehensive design method. At present, many new technologies and design auxiliary software have appeared, which effectively improves the design and development efficiency of information management system.
3. Concluding remarks
When designing a computer information management system, we must follow the principles of openness and diversity and adopt an appropriate programming language. In the design, according to the needs of users and the actual situation, appropriate design methods are adopted to improve the development efficiency of computer information management system. With the research and progress of computer information management system, computer information resources can be shared in real time in a wider range, improving its utilization and practical value. We will carry out research work in this field. The wide application of computer information management system will certainly promote the institutionalization, standardization and scientificity of information management in all aspects.

Design principles, methods and principle analysis of computer information management system Part II:
With the continuous development of computer information technology, computer information management system has been widely used in many fields. This paper briefly analyzes the problems existing in the mode of computer information management system, and briefly describes the application of computer information management system in computers.
Key words:
Computer, information management and management system
In recent years, with the rapid development of science and technology, computer management systems have been widely promoted and applied, and the number and types of software that can be applied are also increasing. Some departments and units have adopted special computer information management software, and some departments and units have adopted local area networks. Computer information management system can make group enterprises and units enjoy information through the network and make information service more convenient and fast. In addition, computer work can also organically combine business, retrieval and service, which is convenient for all departments to grasp the development information of the industry in time and collect effective information. However, due to various factors, the computer information management system has been affected in the application process.
First, the problems existing in the old IT management system model.
In the initial IT management system, there are usually two factors that affect the application of computer information management system. On the one hand, the speed of the system is very slow, for example, enterprises need to open documents when selling goods, and it takes several minutes from the beginning to the completion of the whole process. On the other hand, the system data is inaccurate, for example, the actual inventory is inconsistent with the computer inventory, which makes the data of the unit or company have a great impact on statistics, and also leads to the ineffective use of financial related data, so manual entry is chosen to fill in, which not only increases manpower, but also increases financial resources.
Generally speaking, if the computer management system is not in place in the process of developing the company's business, enterprises and units will face many unnecessary influences. For example, the business operation is relatively complex and the process details are numerous, which will also affect a lot. Relevant personnel and some projects need to be completed in a short time, but there is not enough funds, which will involve some restrictions such as personnel factors. The computer management system is outdated or the system structure is chaotic, so it is difficult to maintain. If they are all carried out by hand, there will be irregularities and details that are not in place, which will affect the development of the business and at the same time reduce the progress and have a great negative impact on the company.
Second, the feasibility of computer information management system.
With the continuous development of science, computer technology has gradually matured and played a very important role in many fields. Our daily life generally embodies the convenience brought by computer technology. In computer application, information management system is a very important part, which has great advantages compared with manual management. The internal design of computer information management system endows it with the characteristics of fast retrieval, super secrecy and reliability, and the characteristics of computer itself also make it have larger storage space and longer information preservation time. These advantages greatly improve the efficiency of information management, and at the same time, these advantages can also make the computer information management system scientific and standardized to a great extent.
If you want to create a new computer management information system, you must analyze its feasibility and necessity. The feasibility of establishing a computer information management system is reflected in many aspects such as economy, technology and operation. The new system can obtain the most effective economic benefits with the minimum development cost. In the whole development process, it will involve many problems such as required personnel, software technology, cost and so on.
(1) Economic feasibility.
Modern computer information management systems all adopt network mode, and network computing and management can greatly improve work efficiency and talent utilization rate, thus creating more favorable value for enterprises and groups. Computer information management reduces the amount of labor for manual management, which is equivalent to reducing labor costs. At the same time, computer information management has also improved the utilization rate of talents, which is a very obvious achievement of network management in the information age.
(2) Technical feasibility.
Every computer information management system has the function of editing its own language, and such a system can also choose the appropriate language to establish a database according to its own actual situation. At present, most databases choose Microsoft Access 2000 database, and JAVA language is the most commonly used language, because JAVA language has platform-independent characteristics, so it can run on any computer.
(3) Feasibility of operation.
After careful design and testing, the computer information management system is very simple and convenient to operate. At the same time, there is no high requirement for computer operators. As long as they have some online experience, they can meet the different needs of different users. In addition, it also contributes to the effective management of group enterprises and units. Only simple operation is needed to complete the required requirements, and the user's learning and mastering time is short, which can improve its acceptability.
Third, implement computer information management system.
Computer information management is very important and a long-term work. At the beginning, it can't be transformed to a large extent, and it needs to be infiltrated step by step. The implementation of computer information management system can be divided into hardware construction, software design, use and maintenance.
(1) hardware construction.
The purpose of developing computer information management system is to establish a scientific and practical network system. This networking system includes indoor LAN system and Internet access. The computer information management system establishes a new database on the infrastructure of indoor LAN, and the application platform completed by www service allows users to query the required data and information quickly and conveniently.
(2) Software design.
According to the main functions of computer information management system, develop or purchase application software. First of all, we should make a software system demand plan, which must be supported by professional software technicians. To obtain a detailed software requirement, on the one hand, it should conform to the national standard of computer information management, on the other hand, it should conform to the particularity of enterprise information management.
(3) Use and maintenance.
After the computer information management system began to be used normally, it entered the maintenance stage. In the maintenance stage, it is necessary to fill the internal data of the computer scientifically and effectively to make the system serve the enterprise or group more effectively and better.
The information processing of a complete computer management system can basically be divided into four processes, namely, data acquisition, data processing, data analysis and decision-making consultation and support. Usually, as long as the computer management system selected by an enterprise or group is suitable for its own actual situation, the efficiency of information management will be effectively improved.

Design principles, methods and principle analysis of computer information management system Part III:
With the continuous development of information technology, computers are playing an increasingly important role in human life. Ensuring the safe and efficient use of computers is an important task for relevant researchers at present. In order to achieve this, it is of great significance to use computer database system to manage computer information. The application of computer database system in information management is analyzed in detail.
Key words:
Computer; Database system; Information management; App application
Database management system is an indispensable and important system in the process of computer operation. With the support of the operating system, the database management system can integrate all kinds of irrelevant data resources, and at the same time, structure and digitize the data, and finally achieve the effect of efficient information management. In addition, the database system can safely store and transmit data when in use, which is of great significance to the safe use of computers and the improvement of efficiency [1]. This study actually analyzes the application method and significance of database system in the process of computer information management.
1, concept
Computer database system is actually a collection of data, which is structured data to meet or achieve a certain purpose. Generally speaking, computer database system has its unique characteristics. First of all, the computer database system needs to be structured. Although some structures have actually been entered into the file system of the computer, there is no relationship between the internal records. But with the help of computer database system, the whole data can be structured. It can be said that structuralization is the biggest feature of computer database. In addition, the computer database has a high degree of data enjoyment, and the computer database is not lengthy, so it will be very convenient to expand if you need to add data, especially in the process of data enjoyment, which can effectively avoid incompatibility and inconsistency between data in time [2]. Finally, the computer database has high data independence, mainly physical independence and logical independence. Because of this feature, if the data changes logically, the whole data can still remain unchanged, and the data will not be affected by the storage medium, which is of great significance to data security.
2. Application status
Through analysis, it is found that the computer database system is of great significance in computer information management, which shows that it is particularly important to analyze the application of computer database system in the actual information management implementation process. At present, computer database system has been well applied in information management. For example, the current database technology is constantly developing [3]. Up to now, the database systems used have strong operability and practicability, and can be well applied to the process of computer information management. At the same time, the application scope of database system is also expanding. This is actually the general trend and the inevitable development of computer technology. Especially for China, the computer database system has been perfectly applied in the three major industries, and the computer database system has also played a particularly important role in the development of the three major industries. Finally, the security of the database system is improved. In fact, computer data is threatened by many factors at present. Faced with these threats, the current database system has improved its own performance and security, which provides a strong guarantee for data security.
3. Development of computer database system
3. 1 integrating theory with practice
In order to ensure the more perfect use of computer database system, we must pay attention to the combination of theory and practice, so that the security and practicability of computer database system can be obviously improved. This has a considerable role and effect on the management of computer data, and can also help the computer database system to be better applied in the current information management process. At the same time, integrating theory with practice can also lay a solid foundation for the better application of computer database system in actual information management.
3.2 Further enhance the security of computer database system.
Through analysis, we can find that the main goal of computer database system is to make computer information management safer and more efficient. At present, in the actual use of computer database system, its main goal is to ensure the safety of computer information management. Although in most cases, computer database system can ensure the security of computer information management, in the actual use process, the security of computer database system still has a high threat [4]. Especially with the continuous development of computer network computing, computer database system will face more dangers and challenges. If there are risks in computer information management, it is very likely to pose a serious threat to the information security of the computer itself, and may even cause quite serious consequences. Under this premise, it is necessary to continuously improve the applicability and security of the computer database system itself and play a more important role in computer information management.
4. Conclusion
Computer database system is a particularly important system in the use of computers, which is of great significance to the safe use of computers and the improvement of efficiency. This study analyzes the application method and effect of computer database system in computer information management, and provides reference materials for improving the efficiency and security of computer information management.
