A dynamic routing system and working method of multi-target data service layer

Abstract

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.

Description

technical field [0001] The invention relates to a data access system. Background technique [0002] The implementation of the data service layer of the existing application system, such as figure 1 As shown, the user sends a data access request to the business logic interface through the view layer, and the business logic interface is connected to the data service layer, and accesses the database after parsing the operation code. At present, the development of cloud data service technology for information systems has provided new ideas for data access methods of large-scale information business systems. The current data access technology architecture of large-scale business information systems cannot transition smoothly to cloud data services. The verified data service technology has great application risks. At present, the industry lacks an effective strategy to fully carry out cloud data access technology verification on the premise of ensuring the stable operation of th...

Problems solved by technology

[0003] If the existing business logic layer is used to realize the parallel access of the original data service layer and the cloud data service layer, it is necessary to change the program and source code of the business logic interface, such as figure 2 As shown, a data service layer selection module needs to be added between the business logic interface and the data service layer, and the function of the data service layer selection module is realized by software, because it involves the modification of the business logic interface program and source code, it is easy to destroy the original program Therefore, it lacks flexibility in the subsequent modification and improvement process, which is not conducive to the subsequent exploration, research and verification of various heterogeneous databases and data service layer technologies
