Electronic bill processing method and system based on XML(Extensive Markup Language)

Abstract

The invention discloses an electronic bill processing method based on XML(Extensive Markup Language). The method is characterized by comprising the following steps of: selecting key data elements from electronic bill XML files; distributing corresponding fields of relational databases for each key data element and electronic bill types of the electronic bill XML files, and storing the data of the key data elements and the electronic bill types to the corresponding fields; distributing a separate field of the corresponding relational database for the electronic bill XML files, and storing the electronic bill XML files to the separate field, wherein the data of the key data elements in the relational databases are suitable for common service operations.

Description

technical field [0001] The present invention relates to XML data storage, and in particular to an XML-based electronic bill processing method and system. Background technique [0002] Due to the advantages of XML's openness, simplicity, self-describing and interoperability, data exchange based on XML has been widely used in the e-commerce environment, enabling e-commerce companies to exchange information conveniently. As a key part of e-commerce, electronic bills also use XML extensively. In Europe, where electronic bills have been successfully promoted and applied, XML-based data exchange standards (such as OIOXML, UBL, etc.) are the first choice for data transmission of electronic bills. There are relatively mature solutions for the display technology of XML data. XML display methods based on XSLT or CSS, for example, can display XML data in formats such as HTML and PDF. [0003] However, because the traditional relational database lacks support for efficiently processin...

Problems solved by technology

[0004] For the case of electronic bills, there are some frequently accessed business data in the electronic bills. If the method of parsing XML is adopted, the advantages of relational databases can be fully utilized and the efficiency of frequent access to business data can be solved, but it will cost A lot of effort has been devoted to the conversion from XML files to relational databases, and XML presentation technology cannot be directly used. More importantly, this processing method will make the electronic bill processing system lack of scalability and flexibility, for example, it cannot be flexibly expanded New Electronic Note Types

If the method of storing the entire XML file is adopted, there will inevitably be a problem of retrieval efficiency when processing electronic bill business, and it cannot cope with frequent access to business data in electronic bills
