human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "designing applications with distributed databases in a hybrid cloud"):
  Abstract: Designing applications for use in a hybrid cloud has many features. These include dynamic virtualization management and an unknown route switching customers. This makes it impossible to evaluate the query and hence the optimal distribution of data. In this paper, we formulate the main challenges of designing and simulation offer installation for processing.

Includes members:
  Member "optimal control of applications for hybrid cloud services":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "experimental study of the cloud architecture selection for effective big data processing")
  Member "using object relational mapping to create the distributed databases in a hybrid cloud infrastructure":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "experimental study of the cloud architecture selection for effective big data processing")
  Member "concept of feedback in future computing models to cloud systems":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "using object relational mapping to create the distributed databases in a hybrid cloud infrastructure")
  Member "virtual laboratories in cloud infrastructure of educational institutions":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "experimental study of the cloud architecture selection for effective big data processing")
  Member "use of dynamical systems modeling to hybrid cloud database":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "using object relational mapping to create the distributed databases in a hybrid cloud infrastructure")
