A data processing system includes a number of business domains that co-operate with each other, each of the business domains being managed by a separate organisation. The system also includes a register domain, which holds information common to the business domains. Each business domain includes a process for checking whether a particular data item currently exists within that business domain. If it does not exist in that domain but exists in the register domain, the process copies the item from the register domain into the business domain. <IMAGE> |
