Management of contract data

摘要

A method and system for contract processing. Sent by a procurement contract management system (PCMS) to decentralized execution systems is a list of I identifiers identifying a contract dataset in the PCMS earmarked for archiving. The PCMS receives from each DES a return list of M of the I identifiers approved by each DES for archiving. A generated intersection list includes a logical intersection of the return lists received from the decentralized execution systems. If the intersection list is not empty, the PCMS archives each contract dataset identified in the list of I identifiers and appearing in the intersection list and communicates to each DES that the archiving was performed by the PCMS for the contract datasets appearing in the intersection list. If the intersection list is empty, the PCMS communicates to each DES that the archiving will not be performed.
