THE DESIGN OF INFORMATION SYSTEM INTEGRATION ON THE BASIS OF CHAIN GROUP

摘要

The integrated architecture of information system can be researched lengthways and crossways. From the longitudinal aspect, it is a three-level control structure, which includes top production units, dispatching level and bottom production units. From the cross aspect, it is a two-level actualizing structure, which includes the integration of phase -step-level and chain-group. We put forward to the longitudinal design in which top production units, dispatching level and bottom production units are connected by the decision chain, supported by the support chain and construct function main chain for each control level. Meanwhile, from the cross, each phase (top level, production unit level, soft component level), each chain line (decision chain, support chain, function main chain) is integrated by some means.
