Multi-target data service layer dynamic routing system and work method thereof

The invention discloses a multi-target data service layer dynamic routing system and a work method thereof and relates to a data accessing system. If the existing business logic layer is used to realize parallel access of an original data service layer and a cloud data service layer and the programs and source codes with changed business logic interfaces are used, the stability is poor. The system comprises a view module, a business logic interface, a dynamic router connected with the business logic interface, a data service module and a cloud data service module and used for accessing the data service module or the cloud data service module according to the requests of the business logic interface, a dynamic router configuring module used for configuring the dynamic router and connected with the view module, a common data service module connected with the dynamic router and a common database and used for analyzing and accessing the common database, and the cloud data service module connected with the dynamic router and used for accessing a cloud database. By the system, the business logic layer stability of the original application system is guaranteed.
