Data access method and device, storage medium and electronic equipment

The invention relates to a data access method and device, a storage medium and electronic equipment, and relates to the technical field of computers.The method comprises the steps that a target access request is initiated to a target client deployed in a second network segment in response to a target application deployed in a first network segment, a target access request is filtered through a proxy client deployed in a first network segment, the target access request is forwarded to a proxy server deployed in a second network segment, and then the proxy server deployed in the second network segment authenticates the target access request. And forwarding the authenticated target access request to the database server in the second network segment, wherein the database server in the second network segment responds to the target access request. Therefore, by setting the proxy client and the proxy server and limiting access to the proxy client and the proxy server, the security of cross-network-segment network co
