Information exchange method for heterogeneous system

Abstract

The invention discloses an information exchange method for a heterogeneous system. The method comprises the following steps: receiving data published by a publishing system, simultaneously carrying out publisher verification, published data verification and data conversion, and publishing the data to a central site of integrated exchange middleware; acquiring input data from an input message queue at regular time, finding a data storage list, judging an operation type of the data, and distributing a unique main key key-value of the data storage list to finish message input and storage; meanwhile, sending the input message to a published message queue; taking a published message out from the published message queue at regular time, calling subscription rule service and carrying out subscription calculation to form a data subscriber and subscription data information of the data subscriber; meanwhile, sending the subscription information of the subscriber to a subscription message queue; carrying out subscription data pushing of the subscriber. According to the information exchange method disclosed by the invention, the problems of single integration measures, high technical difficulty, high integration cost and long implementation cycle in an integration process of application software are effectively solved.

Description

technical field [0001] The invention relates to the field of software information exchange, in particular to a heterogeneous system information exchange method. Background technique [0002] Middleware (Middleware) is the software between the operating system and the application program, and it is a technical realization that effectively solves the integration of heterogeneous systems. Middleware uses standard interfaces to improve system portability; adopts standard protocols to improve system interoperability, so many standardized work middleware has become the main component. The middleware defines a relatively stable high-level application environment through the program interface. No matter how the underlying computer hardware and system software are updated, only the middleware needs to be updated and the external service interface definition of the middleware remains unchanged. No modification is required, thus effectively protecting the significant investment of the...

AI Technical Summary

Problems solved by technology

[0004] Existing technologies cannot solidify exchange standards, resulting in weak exchange standard definition and expansion capabilities for integrated exchange middleware; existing technologies define standard interface specifications, allowing the access system to undergo program modification to complete integration with middleware, making The integration time period is long, the coordination workload is heavy, and the access cost is high

[0005] In the existing technology, there is no unified standard definition for external information exchange of different application software manufacturers, and seamless integration with heterogeneous systems cannot be realized, and the complexity and access cost of software integration are high
