Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0031]At present, in the related technologies of data access across data sources, the network between multiple data sources can be opened up to achieve data access across data sources, but opening up the network requires high manpower and material costs, and may also affect the data source. In another way, data from multiple data sources can be migrated to one data source, and data federation qu...

Abstract

The invention provides a data access method, a data access device and a server. If a received data access request is associated with at least two data sources in a plurality of data sources, a data query plan of the data sources associated with the data access request is generated; the data query plan is sent to a data source associated with the data access request by utilizing a Spark calculationengine and an encryption connector, and access data corresponding to the data access request returns through the data source. In the mode, the generated data query plan is encrypted and sent to the corresponding data source through the Spark calculation engine and the encryption connector, so that cross-data-source data access is realized, and data federation query among multiple data sources isrealized at a relatively low cost while the data security of each data source is ensured.

Description

technical field [0001] The present invention relates to the technical field of data access, in particular to a data access method, device and server. Background technique [0002] Usually, different data sources may be deployed in different private networks, which can be virtual private clouds or computer rooms; in order to realize data federation query among multiple data sources, data access across data sources needs to be realized first. In related technologies, the network between multiple data sources can be opened up to achieve data access across data sources, but opening up the network requires high manpower and material costs, and may also pose a threat to the data security of the data source; In one way, data from multiple data sources can be migrated to one data source, and data federation query can be realized in this data source, but the way of data migration also needs a lot of manpower and material resources, and the implementation cost is high.
