Information processing system, information processing apparatus, and information processing method for implementing a system rollback process

An information processing apparatus comprising:

• a first storage unit configured to store, with respect to an application for executing a first process corresponding to a series of processes using electronic data, application identification information that identifies the application in association with information relating to the first process;
• a receiving unit configured to receive a request from a device connected to the information processing system, the request including the application identification information and information relating to electronic data generated using the device;
• a process execution unit configured to execute the first process based on the information relating to the first process stored in the first storage unit in association with the application identification information that is included in the request received by the receiving unit, the process execution unit executing the first process with respect to generated electronic data based on the information relating to the generated electronic data that is included in the request;
• and
• a process generation unit configured to generate information relating to a second process when an error has occurred during execution of the first process executed by the process execution unit, the second process corresponding to a series of rollback processes for rolling back a processing result of the first process executed by the process execution unit until the error has occurred,
• wherein
• the process execution unit executes the second process based on the information relating to the second process generated by the process generation unit when the error has occurred during the execution of the first process to undo the processing result of the first process at a designated storage destination until the error occurred, and
• the process generation unit
• refers to flow progress information including information relating to processes of the first process that have been executed and successively acquires processes that have been executed before the error has occurred in the execution of the first process, and
• refers to rollback process information for rolling back a processing result of each of the processes of the first process that have been executed to a state before execution of the first process, and acquires corresponding rollback processes in a reverse order from an order in which the processes were acquired to generate a second process.

An information processing method implemented by an information processing system including a first storage unit configured to store, with respect to an application for executing a first process corresponding to a series of processes using electronic data, application identification information that identifies the application in association with information relating to the first process, the information processing method comprising:

• a receiving step of receiving a request from a device connected to the information processing system, the request including the application identification information and information relating to electronic data generated using the device;
• a process execution step of executing the first process based on the information relating to the first process stored in the first storage unit in association with the application identification information that is included in the request received in the receiving step, the process execution step executing the first process with respect to generated electronic data based on the information relating to the generated electronic data that is included in the request;
• and
• a process generation step of generating information relating to a second process when an error has occurred during execution of the first process executed in the process execution step, the second process corresponding to a series of rollback processes for rolling back a processing result of the first process executed in the process execution step until the error has occurred,
• wherein
• the process execution step includes executing the second process based on the information relating to the second process generated in the process generation step when the error has occurred during the execution of the first process to undo the processing result of the first process at a designated storage destination until the error occurred, and
• the process generation unit
• refers to flow progress information including information relating to processes of the first process that have been executed and successively acquires processes that have been executed before the error has occurred in the execution of the first process, and
• refers to rollback process information for rolling back a processing result of each of the processes of the first process that have been executed to a state before execution of the first process, and acquires corresponding rollback processes in a reverse order from an order in which the processes were acquired to generate a second process.
