Case Study: County of Santa Clara achieves unified welfare case management and real-time fraud detection with TigerGraph

How the County of Santa Clara Improves the Management of Welfare Services Using TigerGraph

The County of Santa Clara, a government serving 1.9 million residents with more than 22,000 employees across 70 agencies, faced a complex identity and benefits-management problem: roughly half a million welfare recipients existed across multiple legacy case systems, making it difficult to determine who was who and to see family/household relationships needed to prevent duplicate benefits or missed entitlements. To address this, the County of Santa Clara selected TigerGraph’s native, parallel graph database and analytics platform to support Master Data Management and entity resolution across its disparate relational sources.

TigerGraph implemented a graph-based solution that connected multiple relational feeds into a single, queryable graph to merge records, reveal household and cross-household relationships, and support fraud detection. The result was immediate — queries and relationship traversals that once took hours or days now return in real time — enabling the county to consolidate benefits across households, more quickly identify potential double-dipping or abuse, and operationalize MDM across ~500,000 beneficiary records using TigerGraph.
