In this paper we present NexusDSEditor - an integrated tool for the stream processing middleware NexusDS. NexusDSEditor is an extension module for the NexusEditor and supports developers with designing new streaming applications by providing an integrated tool for orchestrating stream query graphs, define the deployment of query graph fragments to execution nodes, and analyzing data streams. In this paper we demonstrate these single steps and show how NexusDSEditor supports developing streaming data applications for the NexusDS platform by hiding complexity and providing an intuitive user interface.
