The Designment And Development Of The Tianjin Customs Decision-supported System

This paper describes the Tianjin Customs decision-supported System's background ,main functions and testing methods.As two sub-systems of the Tianjin Customs decision-supported System , queueing services and modify/cancel requisitions have defferent functions . Queueing services have many functions, such as online queueing, declaration management and contrasting data. Using the modify/cancel requisitions could take the customs declaration in many uses.Based on the object-oriented software development methods and ASP.NET technology, the Tianjin Customs decision-supported System constituted with popular 3-layers distributed structures and SQL Server 2000 database. This system has high-level technology, expansibility, strongbility and maneuverability. Because of reasonable risk control in the designment, the system could run safety. The system also has many advantages, such as strategy filtration, authentication, timer-backup, injection recovery and several fault degrees. Using efficiency performance testings and forecastings, this system could avoid the bottle-neck in runtime. This system could improve efficiency of customs. In the declaring hall, the order and query/statistics performance has been improved by this system. This system could improve the justice in the customs declaration course. Along the safety manmagement measure, this system also has stability and credibility in the runtime.
