Embodiment Construction

[0038] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.

[0039] Such as figure 1 Shown:

[0040] A method for realizing synchronous online exchange and sharing of heterogeneous databases, which is used to realize synchronous online exchange and sharing of data between heterogeneous databases, defines the database that actively initiates data exchange or sharing requests as the access terminal, and defines the database that passively accepts data exchange or The shared database is the receiving end.

[0041] In this embodiment, four heterogeneous databases are taken as examples for illustration, such as figure 1 Shown includes database A, database B, database C, and database D, but it should be understood that the number of data that can realize data sharing and exchange in the present invention is not ...

Abstract

The invention relates to a method for realizing synchronous and online exchange and sharing of heterogeneous databases, which is used for realizing the synchronous and online exchange and sharing of data between the heterogeneous databases. The method comprises the following steps: S1: establishing a sharing sever for realizing data exchange and sharing of the plurality of heterogeneous databases;S2: sending a data exchange or sharing request by an accessing terminal; S3: receiving an accessing request by the sharing sever and identifying an accessing authority; if the accessing terminal hasthe authority, identifying a structure type of the database of the accessing terminal; otherwise, refusing and stopping requiring; S4: calling corresponding exchange or sharing data by the sharing sever, and converting the exchange or sharing data into a corresponding format according to the structure type of the database of the accessing terminal and sending to the accessing terminal. The systemhas a simple framework and can realize the data exchange or sharing within short time.

Description

technical field [0001] The invention relates to the field of databases, in particular to a method for realizing synchronous online exchange and sharing of heterogeneous databases. Background technique [0002] A heterogeneous database system is a collection of related multiple database systems, which can realize data sharing and transparent access. Several database systems already existed before joining the heterogeneous database system, and have their own data array management system and external database. Each component of the database system has its own autonomy. While realizing data sharing, each database system still has its own application characteristics, integrity control and security control. The heterogeneity of heterogeneous database systems is mainly reflected in the following aspects: [0003] The computer architecture is heterogeneous, and each participating database can run on mainframes, minicomputers, workstations, PCs or embedded systems. [0004] The het...
