Systems and methods for use in data coupling among data structures

Abstract

Systems and methods are provided for coupling data structures in different domains to provide cross-domain data access. One example computer-implemented method includes receiving, from a requestor, an access request including a case type and indicators for multiple domains and determining restrictions associated with the domains. The method also includes compiling a first message key specific to the access request and transmitting the first message key to the requestor. The method further includes receiving an information request including a second message key and a query specific to a person, verifying the second message key based on the first message key, and coupling multiple knowledge graphs for multiple data structures across the domains. The method then includes, in response to verifying the second message key, submitting the query from the information request to the data structures of the coupled knowledge graphs and providing a response to the query to the requestor.
