System introduction:
Nowadays, the power of science and technology is becoming more and more powerful. By combining with more mature computer technology, it has promoted the development of many industries such as schools, medical care, and shopping malls. In order to adapt to the changes of the times, various industries have carried out management informatization construction by combining technologies such as the Internet and artificial intelligence. The traditional information management model mainly counts and stores literary information through manual recording. This management model is easy to lose information and is inconvenient for managers to update and query relevant data. Compared with the traditional management model, the information management model mainly uses computers to store and manage relevant information records. The operation is simple and convenient, and the specific flexibility is strong. It is easy to query and update data, which is conducive to relevant personnel within the same time. , complete more work, and reduce the probability of staff errors as much as possible. On the idea integrated development platform, the literature website adopts the B/S development structure model, and uses Java language to write relevant codes, design system function modules, MySQL database to design data tables, store literary information, and Tomcat server to publish system URLs and process requests. and response messages. The development of this system improves the working mode of managers in related industries, which is conducive to simplifying work processes, accelerating work progress, and improving information processing efficiency.
Keywords: Literary website; Java language; B/S architecture; MySQL database
The overall development process of this system is carried out using the B/S structure model. System-related functions are designed using Java language, MySQL database and other technologies. After the functional design is completed, the system can be run and used by using a browser. Through the relevant content of the requirements analysis, the main functional design of the system can be basically determined. The users of the WEB-based literature network are mainly divided into administrator roles and user roles. The main functional requirements include user management, novel information management, reading record management, etc. The overall functional design diagram of the system is shown in Figure 4-1.
When the program is handed over to the user for use, the operation flow chart of the program needs to be provided, so that the user can easily understand the specific working steps of the program. Nowadays, the operation process of the program has a general standard, that is, first submit the login data through the login page, After the program is verified correctly, the user can operate the corresponding function on the program function operation area page.
