Abstract: The present invention provides a distributed processing system for a graph query language and a distributed processing method for a query language thereof. The distributed processing system for a graph query language according to the present invention includes: a client configured to receive the graph query language; a server configured to receive the graph query language from the client, transmit information for query processing for the graph query language to a plurality of dispersively disposed data processing apparatuses, and integrate results of the query processings received from the data processing apparatuses to transmit the integrated results to the client; and the plurality of data processing apparatuses configured to receive the information for the query processing from the server to determine whether the query processing may be performed, and transmit the results of the query processings to the server.

Abstract: The present invention provides a database capable of integrated query processing and a data processing method thereof. The database capable of integrated query processing includes: a storage unit configured to store data including relational data, and graph data; a converter configured to convert a query language for a property graph data model for processing the graph data into a relational algebra that is a statement in an intermediate stage; and a controller configured to control the converter so as to convert the query language for the property graph data model in an input integrated query into a syntactic statement structure, and convert the query language for the property graph data model included in the query into the relational algebra, when the integrated query, in which the query language for the property graph data model and the relational query language are mixed, is input.
