Layered Technology for Software Development

The Method and Practice of Application of Layered Technology in Software Development

Layering technology refers to the stage of computer software development, which divides and develops the software according to the difference in structure and function, solves the development problems from different levels, and ensures the close cooperation of different links and the internal logic. relation. In the process of software development, compared with single-layer technology, the application effect and comprehensive effect of layered technology are higher. Layered development technology mainly includes two-layer development, three-layer development, four-layer development, five-layer development and middleware development. technology. The number of layers of software development will change according to the actual situation, the requirements of users are different, and the requirements of different layers are also quite different.

1.The characteristics of layered technology in software development

(1) Strong pertinence: Since the computer software development system is relatively complex, and the functions of different computer software are also quite different, in order to improve the efficiency of software development, it must be pertinent. The layering technology clearly divides the functions of the computer system, divides the complex system into several fields with different functions, and different fields are handled by their own virtual layers. In this way, even if there is a problem in a certain field, it will not affect the whole, thus effectively avoiding the continuity problem of the software development system.

(2) Strong flexibility and expandability: layered technology can effectively improve the flexibility and reliability of computer system operation, flexibly transform the original system during the development process, and then achieve the effect of shortening the development time of complex software. It can also guarantee the quality of the developed software. Layering technology can also moderately expand and upgrade software functions in a targeted manner, fundamentally change the upper and lower layers and functional layers of the system, to better meet the needs of computer software users, and improve and adjust different functional layers of the software system. Classify according to the needs, improve the analysis ability of the software, and finally optimize and upgrade the software, which effectively improves the reusability and scalability. Because of the strong flexibility of layering technology, it can also make the function of software better.

(3) Strong technicality: layered technology can enable computers to define different interfaces by using layered technology, and achieve the greatest degree of seamless docking through standardized interfaces. Through such technical means, the relevance and difference of software can be improved , effectiveness, rationality and stability, improve the overall quality of computer software, reduce development costs, enhance teamwork capabilities, and ensure the warranty period and use efficiency of software.

2. Specific application of layering technology in computer software development

2.1 Application of double-layer technology

There are two main endpoints in the two-layer technology, the client and the server. Customers can better improve the quality of the user interface through corresponding users, and effectively deal with the internal logical relationship. In this process, the server can receive user demand information from various levels, and then summarize the information inside the computer before putting it into use. Double-layer technology plays an incomparable role in improving work efficiency. If the user uses too much, the server will be paralyzed, and the computer will even be paralyzed in it. It should be said that the internal networking systems of many large companies operate on the basis of double-layer technology. And can have a good use effect in the future.

2.2 Three-layer technology

The three-layer technology is developed on the basis of the two-layer technology. It can even be said that it was developed on the basis of the second floor. For example, such a three-tier technology can help courier companies store more information, and effectively improve the efficiency of computer access for similar courier companies and logistics companies, and finally improve work efficiency. Compared with the two-layer technology, the three-layer technology will have a greater improvement and strengthening ability, and finally improve the access efficiency of the computer server.

2.3 Four-layer management technology

If there is no way to use double-layer technology and three-layer technology in the process of computer operation to make the computer run effectively in an effective environment. In particular, it is necessary to better integrate the database, interface layer and business processing layer within the three-tier technology, so as to better shorten the impact between the various levels. All four-layer technologies are extensions of three-layer technologies.

The four-tier management technique is often applied to the management process of the library. In particular, it can better integrate the book resources in different periods and different regions, and finally form a database. In this way, we can better carry out informatization construction by fully enabling these digital services.

2.4 Five-layer technology

The five-tier technology itself is an expansion of the four-tier technology, and some large supermarkets will also use the five-tier technology to manage in the process of operation and management. Such five-layer technology can be widely used in various modules in the supermarket management process. First, if the five-layer technology is applied to the process of product entry, it is possible to comprehensively establish and maintain various information codes, and maintain and query personnel files in a timely manner. Cashier password and other related parameters. Second, the business management module can mainly manage the inventory of goods, and better summarize including return subpoenas, price adjustments, querying product balances, collecting product details and other types of business. Thirdly, the sales module can conduct a comprehensive query on the data at the front desk, and effectively monitor the return information, discount information, credit card information and the sales performance of the cashier. It is also necessary to change and monitor relevant sales data in a timely manner.

It should be said that the five-layer technology is at the highest level in the computer hierarchy, and it is believed that it will be more widely used in the future.

epilogue

The development of computer software, as an important link that can improve computer functions, is directly related to whether computers can provide convenience for people's daily life. Among them, the layered technology in computer software development is an important development technology, and its application effect is better. , can adapt to today's technological trends, and has broad development prospects, including two-layer technology, three-layer technology, four-layer technology, five-layer technology and middleware technology. Studying the application method and practice of this layered technology can not only meet the individual needs of software users, optimize the performance of computer software systems, but also ensure the efficiency and security of user information, and improve the speed of software development by software development companies. Save the development cost of the enterprise.
