A Mainstream Relational Database Table Schema Objectification and Virtualization Method

Abstract

An objectification and virtualization mechanism for a mode of a mainstream relational database table. Rational database tables with huge physical differences are converted into a uniform object model, that is, each of the database tables is simply regarded as a p-v object instance system, and each database table field is converted into a pojo instance to serve as a key attribute of the p-v object instance system and is persistent in a cloud database meta node database so as to form a virtual table resource. Thus, a complex physical structure of a multi-element heterogeneous database is evolved into a uniform virtual database platform with a relatively simple logic, a mapping is established between a logic element and a physical element, and an operation mode of concept of a logic layer is defined and mapped into an operation mode for the physical element, complex underlying physical details and differences are shielded, and a cloud database virtualization platform uniformly based on an object model operation is provided. The solution solves the problem that database data cannot be uniformly managed and cannot interconnect and interwork, and thus can be used for the 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 method for objectifying and virtualizing table patterns of mainstream relational databases. 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 int...

Problems solved by technology

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