Multi-data source dynamic isolation access method

Abstract

The invention discloses a multi-data-source dynamical isolated access method. Aiming at requirements of multi-data-source dynamic access, the dynamic database connection, access and multi-transaction processing technologies are utilized, and multi-data-source dynamic isolated access is realized through three stages including multi-data-source dynamic connection, multi-data-source dynamic inquiry and multi-data-source isolated storage. High-speed access and management of multiple (unlimited number) data sources can be completed simultaneously, and by the data isolation technology, non-interfering of data transmission of the multiple data sources is guaranteed and safety and high speed are realized, so that oneness and inefficiency of operations on data sources of conventional software are overcome. The multi-data-source dynamical isolated access method can be widely applied to software development environments needing simultaneous access to different data-source data, especially SaaS (software as a service) and PaaS (platform as a service) environments in the field of cloud computation.

Description

technical field [0001] The invention belongs to the technical field of computer data access and management, and in particular relates to a dynamic isolation access method for multiple data sources. Background technique [0002] With the vigorous development of cloud computing and the Internet, many systems and platforms will be faced with massive amounts of data, and the amount of these data is increasing at an explosive speed, which directly leads to the increasing size of many software architectures and increasing processing power. It is these huge massive data that support the operation of these software and provide services for users. For software services, not only need to face a large amount of data, but also face data from different data sources, including from different database servers. , different data structures, distributed data storage and other environments. [0003] At present, for massive data from a single data source, many database services provide powerfu...

Problems solved by technology

[0004] In view of the increasingly large software system and the increasingly complex data structure, especially the development of cloud computing technology, the data source that the software needs to process is no longer a single target database, but may be multiple different data sources. The traditional database Access technology can only operate one data source in a software system. Although there are some improved technologies that can be configured to achieve access to multiple data sources, these technologies are essentially simple extensions to a single access technology, and need to be specified in advance. The location and number of data sources, that is to say, the parameters of the target database must be set in advance, and cannot be dynamically and automatically expanded according to needs, which does not meet the requirements of multi-database access
