摘要

Processing of the directed acyclic graph query in DUO is studied in this paper. DUO is a graphical query language for the database based on labeled directed graphs. The directed acyclic graph query is the query whose structure is the directed acyclic graph. First, this paper briefly describes DUO. Next, the processing of directed acyclic graph query on the DUO interpreter is presented. Finally, examples of the execution of the interpreter are shown.
