System and method of integrating databases based on knowledge graph

This invention describes an AI system designed to combine information from many different databases, even if they are structured differently. It first converts each database's information into a "knowledge graph," which is like a map of how the data is connected. These maps are then fed into two separate AI learning models to identify correlations between data fields across the databases. The system then produces two integrated knowledge graphs showing these connections, ultimately creating a single, unified knowledge graph that brings all the correlated information together.
