Research of flexible data integration based on event-driven

The development period of Enterprise Application Integration(EAI) is always long and the normal data integration is simple at data level. For integrating enterprise data effectively, the flexible data integration based on event-driven was proposed. This model, including event management, job management and data adapter, was built on the old enterprise information systems as bus model and could customize integration job. The original system, based on event-driven flexible data integration architecture, was developed by Java. It can be applied to the data integration of different information systems, which request flexibility.
