WAMDM means " Web And Mobile Data Management", Which is Professor Xiaofeng Meng( local mirror )'s research lab and is affiliated with the Key Laboratory for Data Engineering and Knowledge Engineering MOE and the Department of Computer Science, School of Information, Renmin University of China.

The research vision in WAMDM is how database techniques would fit into the Web and Mobile computing environments. The research style in our lab is having two tracks - research and system - in order to ensure that the research is actually applied. Innovative data systems research is our goal.

WAMDM Lab has been conducting database related research for many years, and is considered one of the best database groups in the country. It's projects range from the Web Data Management, XML Data Management to Mobile Data Management, focusing on Web data extraction, Deep Web data integration, dataspace for PIM, native XML Database, ontology data management, road network moving objects management, smart DBMS, RIFD data management, data management in Context-aware computing, Location privacy, outsourced databases security, etc..

The site contains information on the projects that are currently in progress and the people in the group. You can also find information on the weekly seminar and annual report. In addition, this site hosts the following webpages:

	Database Society of China Computer Federation
	MDM2008
	WISA2007
	ICDE 2009

WAMDM Lab locates at the First floor, Computer Building, Renmin University.
