An adaptive heterogeneous database integration framework based on Web service composition techniques

To improve adaptability and flexibility of heterogeneous database integration system, the paper proposed a heterogeneous database integration framework based on Web services composition which is implemented by Web services composition template. The paper also adopted granular computing to optimize Web services composition to improve efficiency and quality of heterogeneous integration systems. The experiments show that the Web service composition techniques based on granular computing can increase the adaptability and flexibility of heterogeneous database integration system.
