Claim 2:
3. A distribution management system, comprising;
a plurality of distribution management apparatuses each of which includes:
one or more processors; and
a memory storing instructions that when executed by the one or more processors, configures the one or more processors to:
store rule master information indicating, for each of a plurality of types of processes of distribution of a predetermined product, whether a concerned party has a forward access right and a backward access right,
receive a plurality of transaction data from a predetermined terminal, each transaction data indicating information of a completed processes among a plurality of processes and a concerned party in the completed process,
generate access right information for each of the plurality of the received transaction data, the access right information indicating, for each transaction, whether the concerned party in the completed process has the forward access right and the backward access right, and the type of the respective process, the forward access right indicating a right to access data of processes downstream from the completed process and the backward access right indicating a right to access data of processes upstream from the completed process,
receive an information provision request for a process in the distribution of the product from a predetermined terminal,
determine whether a sender of the received information provision request has the downstream access right and/or has the upstream access right based on the generated access right information,
identify, based on the determination, information of a downstream process and/or an upstream process to which the sender is determined to have the right to access;
transmit the identified information on the process to the terminal that has sent the information provision request,
upon receipt of the transaction data, transfer the received transaction data to the other distribution management apparatuses, and
receive, from the other distribution management apparatuses, generation results of predetermined data generated by the other distribution management apparatuses based on the transferred transaction data.
