AI Technical Summary

Problems solved by technology

A lot of scientific and technological data is repeatedly collected at a low level, and the degree of sharing is low
[0007] 2) The development of scientific and technological data resources lacks standards and norms
[0010] 2) "Information islands" will have a very adverse impact on daily management and business operations. If the problem of "information islands" is not resolved in time, more new "information islands" will emerge
Causes stagnant levels of data sharing

Embodiment Construction

[0024] figure 1 A structural diagram of a heterogeneous database integration system according to the first embodiment of the present invention is disclosed. refer to figure 1 As shown, the heterogeneous database integration system includes: a set of bottom databases 10 , a database integration device 11 , an upper database 12 and an access interface 13 .

[0025] A group of underlying databases 10 are constructed according to different data structures, forming heterogeneous databases. In one embodiment, for example figure 1 In the illustrated embodiment, a group of underlying databases 10 includes a database constructed according to the Oracle data structure, such as figure 1 The underlying database 101 in , or a database constructed according to the SQL data structure, for example figure 1 The underlying database 102 in . In another embodiment, a group of underlying databases may also be structured databases or semi-structured databases.

Abstract

The invention discloses a heterogeneous database integration system, which comprises a group of bottom databases, a database integration device, an upper database and an access interface, wherein the bottom databases are constructed according to different data structures; the database integration device is connected with the bottom databases and used for data exchange with each bottom database, the database integration device is used for data exchange with one bottom database by using the data structure consistent with the bottom database, and the database integration device is used for data format conversion for data acquired from the bottom database so that the data with a unified data format are formed; the upper database is connected with the database integration device and used for acquiring data with a unified data format from the database integration device, so that the data in the upper database are synchronous with the data in the bottom databases in content; and the access interface is connected with the upper database and only accesses the upper database, so that the data with the unified data format are acquired.

Description

[0001] technical field [0002] The invention relates to database technology, in particular to a heterogeneous database integration system. [0003] Background technique [0004] Since the birth of computers, human beings have accumulated rich data resources. The popularity of computer networks makes the sharing of data resources a hot topic. However, due to differences in time and space, people use different data sources, and the data types and data access methods of each information system are also very different. This leads to the inability to efficiently exchange and share data between various data sources and systems, becoming an "information island". The problem of data sharing arises from this, and the problem of heterogeneous data sharing has also attracted more and more attention. Heterogeneous data not only refers to the heterogeneity between different database systems, such as Oracle and SQL Server databases, but also includes the heterogeneity between differe...
