The invention relates to a cross-database interactive service platform. The cross-database interactive service platform comprises a data layer which provides database data information, a service layerwhich carries a RESTful API, a bus layer which carries a light-weight service bus and an application layer; the data layer sends data information to the service layer; the application layer receivesan access request signal and sends the access request signal to the bus layer; the light-weight service bus of the bus layer performs arranging management on preset service information of the bus layer and data information received by the service layer so as to obtain an arrangement result and outputs the arrangement result to the application layer so as to obtain a access result. As the RESTful API and the light-weight service bus are adopted to perform arranging management on service processes and data information, the cross-database interactive service platform becomes more convenient and more efficient, a use disadvantage that a new data service needs to be developed repeatedly when a service demand changes is avoided, efficient and safe data interactive access services between different types of databases are realized, service rapid deployment and flexible configuration are satisfied, and good applicability is realized.
