摘要：An independent distributed database system comprising a plurality of siteswherein all users at all sites work off-line with local data. All application transactions areagainst the local database only, and every site stores \"all and only\" the data it needs. On-line transactions occur only in the background, including a periodical \"synch\" betweensites that transmits any changes to data of interest to that site. If the backgroundoperations are interrupted or the network is temporarily unavailable, the user does notsee new changes made at other sites until the data link is available again, but is otherwiseunaffected. It is a feature that no site acts as a \"server\" for any other site. Some sites maystore more data or have more users than others, but all sites are logically peers.
