Heterogeneous database storage unified interface and database access method

Abstract

The invention relates to a heterogeneous database storage unified interface and a database access method by using the same. The interface mainly comprises a heterogeneous database drive management unit, a heterogeneous database connection pool, a heterogeneous database operation unit, a heterogeneous database connection configuration unit and a unified external API (Application Program Interface) unit. Through the heterogeneous database storage unified interface, a plurality of application processes can simultaneously access databases with different structures without modifying the databases and / or programs or knowing the kinds of the databases, so that the design of an application program can completely independent of different database treatment designs to achieve the aim that program design is irrelevant with the databases; and the operation APIs of all the databases are same, therefore, application codes are simplified, the maintenance is convenient, data transplanting and changing are realized.

Description

technical field [0001] The invention relates to a unified interface for storing heterogeneous databases and a method for simultaneously accessing data when multiple different databases coexist. Background technique [0002] At present, the global enterprise system is getting bigger and bigger, and the total data capacity is about to quadruple every three years. In this case, the more widely the data storage may be distributed, the data of the same system may be placed in different databases In the process, or due to the need to upgrade the system to different databases, or to migrate data between different databases, at this time, the methods and methods of accessing different databases of the application system are completely different, resulting in a large amount of upgrade workload and man-hours . Most existing systems are too tightly bound to database applications, causing a lot of inconvenience in the system. Contents of the invention [0003] The technical problem ...
