Preface

Recently, there has been a lot of interest in the application of graphs in different domains. They have been widely used for data modeling of different application domains such as chemical compounds, multimedia databases, protein networks, social networks and semantic web. With the continued emergence and increase of massive and complex structural graph data, a graph database that efficiently supports elementary data management mechanisms is crucially required to effectively understand and utilize any collection of graphs. This workshop focuses on issues related to graph databases. GDM 2011 will be held in conjunction with the IEEE International Conference on Data Engineering (ICDE 2011) in Hannover, Germany. GDM 2011 aims at bringing together researchers in different fields related to graph databases who have common interests in interdisciplinary research. The workshop provides a forum where researchers and practitioners can share and exchange their knowledge and experience.
