%X In a mobile environment,mobile hosts may disconnect from server frequently.To meet the data availablility during mobile hosts are disconnected,data items accessed by transaction must be hoarded to mobile host.A relation graph of realtime transaction is defined in this paper.According to the relation graph,data hoarding algorithms based on time limit,roo mlimit and validity limit are proposed.Using the algorithms,avaibilitiy of data and the timing constraints of realtime transaction are met.
