Abstract

The invention provides a cross-database access method and device. The method comprises the following steps of receiving a data access request from a user terminal, and analyzing to obtain all target database identifiers and target data characteristics corresponding to each target database identifier; searching a target mapping table corresponding to the target database identifier in all stored Hive data mapping tables; when the target data features are found, querying feature information corresponding to the target data features in a target mapping table; accessing a target server provided with a database corresponding to the target mapping table, and acquiring target acquisition data matched with the inquired feature information; and after obtaining the target acquisition data corresponding to all the target mapping tables, carrying out data arrangement on all the target acquisition data, and feeding back an arrangement data result to the user terminal. According to the method, the cross-database associated access of data among a plurality of databases can be realized, the overall data acquisition timeliness is improved, and the realization progress of big data analysis is ensured.

Description

technical field [0001] The present application relates to the technical field of database cross-database access, and in particular, relates to a data cross-database access method and device. Background technique [0002] With the continuous development of science and technology, the application of big data technology is becoming more and more extensive. With the use of big data technology in various industries, different types of data are usually stored in different types of databases. For example, the general-purpose business system Real-time data is usually stored in a relational database built with an oracle database style or a MySQL database style, while historical data of a general-purpose business system is stored in a non-relational database built with an HBase database style or a Hive database style . In this case, big data technology needs to perform data query on each database separately, and correspondingly obtain the desired data from each database before realiz...
