The purpose of introducing system functions is to help users fully understand the system's functional characteristics and usage methods. Through the introduction of system functions, users can clarify the specific operations and business processing capabilities that the system can achieve, thereby evaluating whether the system meets their own needs. The function introduction can also guide users to use the system correctly, improve the application efficiency and performance of the system. For users who are new to the system, a detailed and easily understandable feature introduction is particularly important. It helps users quickly get started and reduces errors or problems caused by incorrect operations. In addition, the introduction of system functions can also provide a basis for subsequent maintenance and upgrade work. When developers need to improve or expand the system, the feature introduction can provide a comprehensive list of features and usage, which helps to formulate a reasonable development plan and plan.
