Cross-environment data synchronization method and system, storage medium and computer

The invention provides a cross-environment data synchronization method and system, a storage medium and a computer, and the cross-environment data synchronization method comprises the steps: obtaining and analyzing change data in a source environment database, and pushing the analyzed change data to a source environment message array; after a message in the source environment message array is received, determining a target environment in which data change needs to be synchronized; obtaining a synchronization table range configured by the target environment, determining whether the change data is valid according to the synchronization table range and the data table of the change data, encrypting the valid change data and then writing the encrypted change data into a public network message queue; and obtaining the message in the public network message queue, performing data decryption, converting the decrypted data into an execution statement, and executing the execution statement in a database in the target en
