Most existing data publish/subscribe systems applied in a particular field, the lack of generality. In order to satisfy the general support for interdisciplinary model, proposed an improved model of general data publish/subscribe. The model supports the configuration and modification of the underlying data types. In order to avoid the impact on the application layer while changing the underlying DDS product, proposed an encapsulation on DDS based on the abstract factory pattern. Finally, through simulation experiments to verify the feasibility of the proposed model, the simulation results show that the improved model can be well applied to various types of data publish/subscribe occasions, with high performance.
