A structured message adaptive conversion method and device

Abstract

The invention discloses a structured message self-adaptive conversion method and device, the device comprises: a data element dictionary and a message self-adaptive conversion middleware; the data element dictionary includes: an atom extracted from a structured message Field and combination parameters, and data element conversion rules designed according to the atomic fields and combination parameters; the data element dictionary is used to support the operation of the message adaptive conversion middleware; the message adaptive conversion middleware is based on The data element dictionary realizes the adaptive conversion of the structured message received by the receiving end through the structured message conversion algorithm. The present invention does not need to customize and develop conversion codes, and does not require strict consistency of message element accuracy, representation, and arrangement order at both ends of the sending and receiving ends. Good operability and other characteristics.

Description

technical field [0001] The invention relates to the field of computer application software, in particular to a structured message self-adaptive conversion method and device. Background technique [0002] Structured message conversion is an important step in the integration of complex systems. By adapting and converting data messages of different formats, different element precisions, different representation methods, and different orderings, the integration, expansion and integration of complex heterogeneous systems can be realized. interoperability. Currently more mature methods include heterogeneous message conversion for custom code and message format conversion based on public data model. The former is suitable for system integration with simple composition and structure and fixed information interaction relationship. The advantage is high conversion efficiency, but the disadvantage is that the system needs to be developed through code development. Once integrated, the ...

The former is suitable for system integration with simple composition and structure and fixed information interaction relationship. The advantage is high conversion efficiency, but the disadvantage is that the system needs to be developed through code development. Once integrated, the system connection relationship and information interaction relationship are fixed, making it difficult to realize dynamic system expansion and Upgrade; the latter forms a corresponding data model based on the format descriptions of relational databases, XML files, JSON messages, etc. The data integration of the system can solve the format conversion problem of structured messages, such as the conversion of XML format to JSON format, etc., but it cannot realize the automatic conversion of structured messages with different data element precision, representation mode and arrangement order

[0003] At present, the integration of complex heterogeneous systems generally adopts the heterogeneous message conversion technology for custom codes. According to the fixed message content and format requirements, it customizes and adapts a large number of heterogeneous systems in the system one by one. The operation complexity is high, compatibility and flexibility The performance is poor, and the system needs to be re-adapted when the system is upgraded, and the system integration efficiency is low

However, the message format conversion technology based on the public data model can only complete the format conversion of specific messages and has limited functions, so it is rarely used in practice.
