However, relatively little effort has been devoted to preparing the graph data for analysis, in particular to transform and integrate data from different sources. To support such ETL processes for graph data we investigate transformation operations for property graphs managed by the distributed platform Gradoop. We also provide initial results of a runtime evaluation of the proposed graph data transformations.enGraph analyticsBig DataGraph transformationsData integrationGraph Data Transformations in Gradoop10.18420/btw2019-121617-5468
