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. |
