Abstract: After analyzing the software architecture of a self-help travel strategy generating system,it is found that there are some drawbacks in this system,which cause it to runn slowly and make it difficult to maintain and expand functions.It suggests that the self-help travel strategy generating system use orthogonal software architecture.Based on the traditional orthogonal software architecture,a common shared data component layer is added to improve the performance of the system.The experimental res...
