The R＆D in the database system and its technologies is one of the important research topics in the field. The database R＆D in China took off later but it moves along by giant steps. This report presents the achievements Renmin University of China （RUC） has made in the past 25 years and at the same time addresses some of the research projects we, RUC, are currently working on. The National Natural Science Foundation of China supports and initiates most of our research projects and these successfully conducted projects have produced fruitful results.展开更多

They both use metaphors and visual representation techniques to address typical project management tasks. T-Cube uses a metaphor with the Rubik-Cube whereas MetroMap uses a metaphor with a metro map. The tools have been tested on real project data and a qualitative assessment shows the results of testing the visualizations with users attempting several information retrieval tasks. The utility of the tools has been positively evaluated and the article demonstrates the possibilities of visual approaches in project management.展开更多
