Abstract

The invention discloses a data transfer method and a data transfer device. The data transfer method is applied to a heterogeneous system comprising N data processing systems, and comprises the steps that to-be-transferred data, and M target systems to be sent by the to-be-transferred data are obtained; M external operation description lists corresponding to the M target systems are obtained; the to-be-transferred data is converted to M standard data based on the M external operation description lists; and the M standard data is sent to the M target systems based on the M external operation description lists.

Description

technical field [0001] The present application relates to the field of data processing, and in particular to a data transmission method and device. Background technique [0002] A heterogeneous system refers to a collection of related multiple database systems, which can realize data sharing and transparent access. Each database system already exists before joining the heterogeneous system and has its own database management system. Each component of a heterogeneous database has its own autonomy. While realizing data sharing, each database system still maintains its own application characteristics, integrity control and security control. The heterogeneity of heterogeneous systems is mainly reflected in The following aspects: [0003] (1) Heterogeneity of computer architecture: each participating database in a heterogeneous system can run on mainframe, minicomputer, workstation, single-chip or embedded system respectively; [0004] (2) Heterogeneity of the basic operating s...
