Problem Statement
In the banking sector, detecting fraud in real-time transactions is crucial but often challenging due to the complexity and volume of data involved. Traditional platforms may struggle to deliver timely insights, leading to potential financial losses and security risks.
Solution Overview
Databricks offers a solution through its Lakehouse Platform, combining data lakes and data warehouses to build a real-time fraud detection system for banking transactions. The platform enables the ingestion of data from external systems like EPR/Salesforce, transformation using Delta Live Tables (DLT) for reliable data processing pipelines, secure data governance, and the utilization of Databricks SQL for dashboard creation and fraud analysis. Additionally, machine learning models developed with Databricks AutoML flag risky transactions, and Databricks Model Serving deploys a REST API for real-time inferences with model A/B testing. Orchestration of these steps is managed with Databricks Workflows.
