PROBLEM TO BE SOLVED: To efficiently read a required piece of data at proper timing. SOLUTION: In an information processing system in which a plurality of computers are connected by a communication network and a plurality of different processes are asynchronously executed the computers, the prescribed pieces of data consisting of at least one piece of data is stored in a storage device by correlating them with a sequence number and a processing flag by using a common identification number as a key in the computer 1 and whether or not the prescribed pieces of data are stored in the storage device based on the processing flag by using the identification number as the key in the computer 2. The prescribed pieces of data are read from the storage device by using the common identification number and the sequence number as the key when storage of the prescribed pieces of data is confirmed in the computer 2 or 3.
