Abstract: The data exchange between heterogeneous nodes in the representative instances of data grid has low efficiency. In order to overcome the disadvantage of the data grid, an event-driven based asynchronous message pass model is proposed. The related definitions and the architecture of this model are discussed. The data access middleware of SDG based on this model is also developed. The initial usage shows the event-driven based synchronous message pass model is important for SDG, which has mass data.
