The service layer and offline programming platform

Abstract

This invention provides a service layer and an offline programming platform. The service layer of the offline programming platform includes services constructed based on a distributed database. These services include: a path matching service, a pattern service, a data pool service, a listening service, and a publishing service. The path matching service routes offline programming requests after rule mapping. The pattern service identifies the pattern corresponding to each offline programming request and forwards the request to the corresponding service for processing based on that pattern. The data pool service manages the data from offline programming requests through a data pool. The listening service listens to specified topics and receives messages from those topics. The publishing service sends messages to those topics. This allows for offline programming without a dedicated DDC device, enabling a wider range of applications, significantly improving the customer experience, and facilitating market promotion.
