Semantic acyclicity on graph databases [PDF]
Proceedings of the 32nd ACM SIGMOD-SIGACT-SIGAI symposium on Principles of database systems, 2013 Summary: It is known that unions of acyclic conjunctive queries (CQs) can be evaluated in linear time, as opposed to arbitrary CQs, for which the evaluation problem is NP-complete. It follows from techniques in the area of constraint-satisfaction problems that semantically acyclic unions of CQs -- i.e., unions of CQs that are equivalent to a union of ...

Graph Database Modelling on Malay Architecture IFC Data
Proceedings of the International Conference of Contemporary Affairs in Architecture and Urbanism-ICCAUA, 2021 Architecture is the manifestation of society and its cultural practice. Preserving the architecture is an important thing that must be done both physically and digitally. One of the architectural cultures that must be preserved is Malay architecture.

Which Category Is Better: Benchmarking Relational and Graph Database Management Systems
Data Science and Engineering, 2019 Over decades, relational database management systems (RDBMSs) have been the first choice to manage data. Recently, due to the variety properties of big data, graph database management systems (GDBMSs) have emerged as an important complement to RDBMSs. As
