Abstract

The invention discloses a general data exchange device based on an extensible markup language (XML). The general data exchange device is characterized by comprising a database (DB) 2 XML module and an XML2DB module, wherein the DB2XML module is used for importing data in an original system and generating an XML document; the XML2DB module is used for importing the XML document which is generated by the DB2XML module into a database of a new system; and the DB2XML module is connected with the XML2DB module. By adoption of the general data exchange device based on the XML, when a database table interface of the new system is not compatible with a database interface of the original system during upgrading or replacement of the system, by using the characteristic that the XML is a data description language which is widely used in a network, XML data serve as intermediate data, and data import and export interfaces of the XML and the database are provided, so that the problem that a source database interface is not compatible with a destination database interface is effectively solved, and inter-system seamless migration of all databases is realized.

Description

technical field

[0001] The utility model relates to the field of computers, in particular to a general data exchange device based on XML. Background technique

[0002] With the popularization of computer applications, a large amount of data is stored in the database. When the computer system is upgraded or replaced, it is often necessary to migrate the data of the original system. Data migration refers to cleaning, converting, and loading the data in the old system into the new system. However, when the system is upgraded or replaced, the interface or data storage format of the database in the new system often changes, which is incompatible with the interface or data storage format of the source database, so that the data of the source database cannot be migrated, which in turn causes the system to fail. Upgrade or replacement failed. SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to provide a general data exchange device based on XML, so as to...
