When some products move to other storage in cold chain, the related continuous queries should be also redefined for different storages. To avoid redefining the existing continuous queries, we introduce a new concept of floating continuous query (FCQ) for solving the problem of redefinition of the transformed continuous queries. Dynamic processing of FCQ not only simplifies query management but also improves query processing performance.
