Graph-based data structures are extremely important in the field of representing complex relationships across various domains, such as social networks. Among different types of graphs, property graphs stand out because of their ability to store detailed attributes for nodes and edges. However, the increased data volume presents a significant challenge on how to efficiently query within large-scale property graphs. This project aims to address these performance issues by proposing a system called Facraym, which is optimized for blending visual property graph query and processing. It can efficiently generate query results within large-scale property graphs by utilizing the delay between user actions. It introduces an adaptive index schema, the Adaptive Property Candidates (APC) Index, that stores candidates for each query node and edge, efficiently pruning unavailable candidates to rapidly generate query results. Additionally, a large-scale property graph dataset called Dummy Social Network Dataset is generated, which simulates a huge social network. Experiments were con ducted using Facraym to query within this dataset, and the results were compared with those from a well-known database, Neo4j. Results demonstrate that Facraym reduces waiting time compared to Neo4j when generating results.
