Embodiment 1

[0020] Embodiment 1. A database access method based on cloud computing. Combine below figure 1 The method provided by the present invention is described in detail.

[0021] figure 1 , S101. Receive a database access request sent by a cloud user.

[0022] S102. Match the database metadata carried in the database access request with the metadata of each database in the cloud system to determine the database to be accessed by the data access request.

[0023] Specifically, when a cloud user wishes to access a database in the cloud system, the cloud user sends a database access request to the cloud system, wherein the database access request carries database metadata. When the cloud system receives the database access request sent by the cloud user, the cloud system matches the database metadata carried in the database access request with the database metadata stored in the cloud system to determine the database to be accessed by the database access request.

[0024] S103. Ana...

Embodiment 2

[0034] Embodiment 2, a database access system based on cloud computing. Combine below figure 2 The system provided by the present invention is described in detail.

[0035] figure 2 Among them, the system provided by the present invention includes a request receiving unit 201, a database determining unit 202, an analyzing unit 203, an executing unit 204 and an executing result feedback unit 205.

[0036] Wherein, the request receiving unit 201 is mainly used for receiving a data access request sent by a cloud user.

[0037] The database determining unit 202 is mainly used to match the database metadata carried in the database access request with the metadata of each database in the cloud system, and determine the database to be accessed by the database access request.

[0038] Specifically, when a cloud user wishes to access a database in the cloud system, the cloud user sends a database access request to the cloud system, wherein the database access request carries datab...

Abstract

The invention discloses a database access method and a database access system based on cloud calculation. The database access method based on cloud calculation comprises the following steps of: receiving the database access request sent by a cloud user; matching database metadata carried in the database access request with the metadata of each database in a cloud system, and determining the database to be accessed according to the database access request; analyzing the database access request to obtain an SQL statement; executing the SQL statement on the current database connection of the user to obtain an execution result; converting the execution result to the data format used by the cloud user and then feeding back to the cloud user.

Description

technical field [0001] The invention relates to the technical field of database database access, in particular to a cloud computing-based database access method and system. Background technique [0002] Cloud computing is an emerging business computing model, which distributes computing tasks on a resource pool composed of a large number of computers, enabling various application systems to obtain computing power, storage space and various software services as needed. At present, most of the data access and integration in the network environment use the visitor to directly interact with the DBS (Database System, database system) service interface. This kind of interaction will force users to solve data access and integration problems within the application system, and make managers or management organizations fall into technical problems such as database connection and data format conversion, which increases the complexity and repetition of management automation program deve...
