First of all, the thesis clearly discusses the systematic research content at the very beginning. Secondly, the analysis of system requirements analysis, understand what to do, including business analysis and business process analysis and use case analysis, further clear system requirements. Then, on the basis of understanding the requirements of the system, we need to further design the system, mainly including software architecture pattern, overall functional modules and database design. The software architecture of the project chooses B/S mode and Java technology, and the overall functional modules adopt the top-down hierarchical idea. Then is the realization of the system and code writing to achieve the function. The last chapter of the paper summarizes the experience and summary of the completion of this paper and the development of this project. Through the basketball forum system will make the basketball forum in all aspects of work efficiency to bring substantial improvement.
