A transaction processing system

摘要

A transaction processing system (1) has a set of modules (4 -6) accessed via a router (3). The modules operate independently, but access programs and other modules via a pass co-ordinator (7) which automatically supplies a list of paths in priority order. Data files (10-13) in flat format are accessed separately via the central node (2), as is a database engine (15) an automatic update program (16) takes update information from an external source, writes it to a temporary memory section, and gradually clears this section by use of a structure buffer and a control register in the central node (2) to automatically complete an update.
