Problems solved by technology

[0003] The present invention aims at the phenomenon that the data sources of the existing software application system are diverse, heterogeneous, and different places, which lead to the inability of unified management and interconnection of database data to form information "islands", and provides a mainstream relational database table model object Mechanism of virtualization and virtualization

Embodiment Construction

[0025] figure 1 , including several basic elements of the cloud database virtualization platform, and the correspondence between these basic elements and virtual databases and virtual tables. In general network applications, the application server and the database server connected to the backend serve multiple front-end users, and the database server has its corresponding database. Each network application invokes and customizes its own virtual resource, that is, a virtual table according to its own needs, and then invokes data resources through the virtual resource address and the mapping relationship between the virtual table and the underlying database. When the user scale or data scale of the system expands, the application server and database server can be expanded separately to form a networked cluster service platform. At the same time, when the load of a single database server is too high, multiple tables in one or more libraries can be further split and deployed to ...

Abstract

The invention relates to the technical field of computer application, in particular to a mainstream relation type database table mode objectification and virtualization mechanism. According to the mechanism, relation type database tables huge in physical difference are converted into unified object models, that is, each database table is simply regarded as a p-v object instance system, and each database table field is converted to be a pojo or a simple object instance to serve as the key attribute of the p-v object instance system and arranged in a cloud database element node database in a persistence mode to form virtual table resources, so that the complex physical structure of a multielement heterogeneous database is evolved to be a unified virtual database platform relatively simple in logic, mapping is conducted between logic elements and physical elements, and operation modes of logic layer concepts are defined and mapped to be operation modes of the physical elements, complex underlying physical details and difference are shielded, and a cloud database virtualization platform uniformly based on object model operation is provided. By means of the mainstream relation type database table model objectification and virtualization mechanism, the problem that database data cannot be uniformly managed and the problems of interconnection and interworking are solved, and the mechanism can be used for interconnection and interworking of the database data.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a mainstream relational database table schema objectification and virtualization mechanism. Background technique [0002] Multiple, heterogeneous, and remote data sources are the basic forms of existing software application systems. Due to the complexity of the system business and the different application environments, the databases used are also different; as a result, data between systems cannot be directly interconnected, let alone Unified management. At this stage, the mainstream relational database technologies are inconsistent and difficult to master. It is difficult for developers and maintenance personnel to take care of the management and maintenance of all types of relational databases, let alone realize data interconnection from the underlying physical structure of the database. This will inevitably lead to the data information of each information inter...
