Data Management Lab of Peking Univeristy (abbreviation: PKUMOD) is subordinate to Wangxuan Institute of Computer Technology of Peking University. The lab's director is Lei Zou. Furthermore, PKUMOD is the main support unit of the Knowledge Integration and Intelligent Decision-making Center of the National Engineering Laboratory for Big Data Analysis and Applications (Peking University).

PKUMOD's recent research focuses on graph-based data management, such as streaming graph analysis, distributed graph systems and hardware-accelerated graph computing. The lab is also interested in graph deep learning, as well as natural language question answering system over knowledge graphs. 

Our lab developed a graph database system, gStore, which can perform high-efficient data management and analysis over big RDF data. The natural language question answering system gAnswer is honored as champion in QALD-9.In 2022, the knowledge graph automated construction platform gBuilder will be officially launched
