Problems solved by technology

[0003] When multiple databases are mixed and co-exist, that is, heterogeneous data sources, each business system needs to develop corresponding database access codes and services, and the traditional development model is a typical "chimney" architecture, that is, all software services are Develop and access through MVC (Model-View-Controller, Model-View-Controller) mode, call JDBC or Open Database Connectivity (Open Database Connectivity, ODBC) interface to achieve database access, can not achieve based on lightweight unified access interface, in Integrate and access multiple data sources within the software

Embodiment Construction

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] Such as figure 1 As shown, the traditional development model is a typical "chimney" architecture. When developing and accessing different data sources (Jincang database and Dameng database), it is necessary to develop separately according to different data sources, that is, all software services are passed. MVC carries out development...

Abstract

The invention relates to a unified access method for heterogeneous data sources, wherein the method comprises the steps: receiving a data access request sent by a client, wherein the access request is used for requesting to access any data source in heterogeneous data sources; according to the access request, assembling a corresponding access statement, analyzing a data source corresponding to the access request, and loading a drive program of the data source, to obtain data source connection; and connecting the data source to execute the access statement, receiving a result returned by the data source, packaging the result into a universal class entity, and returning the universal class entity to the client. According to the method, on the premise of ensuring the own characteristics of each database, servitization abstraction is carried out based on the access difference of the heterogeneous data sources, and integrated and unified management and access of the heterogeneous data sources are realized; and a set of universal access interfaces and access rules capable of cross-language and cross-platform heterogeneous databases are designed in a Restful mode, and a unified data access mode is provided for upper-layer applications.

Description

technical field [0001] The invention relates to the technical field of database middleware, in particular to a unified access method for heterogeneous data sources. Background technique [0002] A database is a major warehouse for organizing, storing and managing data in a software system, and the database is usually used as a data source. Localized databases (such as Dameng, Renda Jincang) usually use Java database connection, (JavaDatabase Connectivity, JDBC) and other methods to access, and for different database access, the business system needs to integrate multiple database access drivers and method. Its limitations are: [0003] When multiple databases are mixed and co-exist, that is, heterogeneous data sources, each business system needs to develop corresponding database access codes and services, and the traditional development model is a typical "chimney" architecture, that is, all software services are Develop and access through MVC (Model-View-Controller, Mode...
