A Pre-joined Service Composition Approach with Dynamic Services in a Graph Database
Database-based composition approaches are evolving and coming into researchers’ notice. In this paper, we present a pre-joined service composition approach with dynamic services in a Graph database. Firstly, services’ information is stored in a graph database. Secondly, a composition network is constructed. Last but not least, a solution by converting the composition problem into graph database queries is fetched. Considering that services are dynamic and lead to frequent changes of service compositions, we discuss how to update the graph database, e.g., service addition, disappearance and update. Preliminary experiment indicates that the proposed approach can support service composition with services’ dynamic changes.
