摘要： An event stream processing system having a processor, wherein the processor registers a temporary object when the object of an event message is unregistered in response to the event message from an event generating device, stores the event message in a pending manner, and Issues an error message. The processor converts the temporary object to a permanent object in response to an automatically-issued event generation message in response to the error message, updates state of the object with state value of the held event message, and executes plug-in corresponding to the updated state.

摘要： A data management method causes a computer to execute processing including: creating, when a predetermined data processing program performs data processing, based on an access frequency to a data store, high-frequency state item list information obtained by listing high-frequency state items of which the access frequency is high; determining, when state information that includes a value of the high-frequency state item is written to the data store, whether or not the state information corresponds to the high-frequency state item with reference to the high-frequency state item list information; grouping and writing pieces of the state information of a plurality of the high-frequency state item.
