and S10, splitting the data access service according to actual requirements, and deploying a plurality of data processing services, including a data entry receiving service, a queue cache service and a data processing service.
S20, presetting an interface protocol, and handing over a corresponding interface key to a data push platform (application), wherein the data push platform (application) receives service push data to an entrance of multi-source data through a fixed format, the entrance receiving service provides a uniform entrance service interface for acquiring a data source according to configuration, and the source mode comprises HTTP, Webservice, files and the like.
