We perform a model of information sharing based on webservice , which can be conveniently used in engaging hotels and tickets , etc . because of the using of webservice , the complicated degree of system is quite reduced ; by combining the scripts and webservice behavior , clients can access data from webservice directly and use the information to update web pages dynamically . this new capability is faster and more efficient than the traditional approach , which requires a full refresh of the web page ; the using of xml makes the data exchange much easily ; the transaction and cursor in db keep the security of data - fetching 由于采用web服務(wù),服務(wù)端、客戶端只涉及信息交換接口的定義,從而降低了整個系統(tǒng)的復(fù)雜度;將webservicebehavior技術(shù),和腳本技術(shù)結(jié)合,高效地實現(xiàn)了基于web服務(wù)的信息共享;以xml格式交換數(shù)據(jù),極大方便數(shù)據(jù)的交換及共享;采用組件開發(fā)模式,進一步提高了軟件的開發(fā)效率;事務(wù)和游標在數(shù)據(jù)庫中的使用保證了數(shù)據(jù)提取的安全。
