（作者未知） 2010/10/25
摘要 本文針對第四方物流信息系統(tǒng)建設(shè)中存在的多源異構(gòu)數(shù)據(jù)問題，提出了基于虛擬數(shù)據(jù)倉庫和XML技術(shù)，采用B/W/S(Browser / Web Server / Database Server)結(jié)構(gòu)的第四方物流信息平臺，將多類數(shù)據(jù)以XML的形式從各多源異構(gòu)數(shù)據(jù)源中遷移到數(shù)據(jù)庫服務器上，以解決分布、異構(gòu)環(huán)境下數(shù)據(jù)共享及利用的問題。對其中的虛擬倉庫和XML格式轉(zhuǎn)換器技術(shù)做了詳細說明，并結(jié)合實例進一步說明了轉(zhuǎn)換器的具體實現(xiàn)算法。該平臺具有良好的擴展性、靈活性，實際應用取得了很好的效果。

Abstract: The Fourth Party Logistics Information Platform (FPLIP) is designed to provide a broad spectrum of operational data from complex and distributing data sources strategically placed which as the key input to the Fourth Party Logistics Information System (FPLIS). A new architecture develops for the FPLIP based on virtual data warehouse and XML. This paper presents the FPLIP architecture in which the virtual data warehouse receives a wide range of data from multiple and distributing sources and analyzes the functions and advantages of the virtual data warehouse based on the complex and distributing features of the FPLIP, illustrates the virtual data warehouse and XML format transform method even the XML format transform algorithm through an example. The results show that this open, flexible platform has good application effects.
Keywords: virtual data warehouse; 4PL; XML
