摘要

In order to realize efficient information sharing and interoperability among varying platforms or large-scale systems, in this paper, we present an approach to SOA-based service integration which makes the service granularity flexible to change. Through choreographic description of local fine-grained component service, and provision of this description in form of SOA to an entity that executes it, then the fine-grained component service appears as coarse-grained one. In this way, the flexibility and running efficiency of system are improved. A particular application to logistics customs-clearance information sharing platform is given to demonstrate the design and part implementation of this approach.
