Enterprise Data Integration by Internal and External Systems

ERP helps enterprises to integrate internal information and to improve operating performance and reaction capability. However, it is not enough to depend on ERP if enterprises want to develop quickly. The enterprise also needs several external supporting sub-systems such as personnel management system, equipment management system, etc. These sub-systems maybe outsourcing customized or developed by internal IT staff. They may be distributed in many branches or headquarter to collect the first line of data and then to deliver data to ERP for data integration. Most enterprises use human or timing batch process via internet to deliver data to ERP, but the two methods are not ideal from the view point of efficiency and security. This paper proposes a fast and safe way with both trigger and data replication techniques to deliver in time the distributed data to ERP for data integration.
