How a Leading Bank Is Driving Actionable Intelligence with a Big Data Platform
About the Customer
A leading banking institution with 700+ branches with over 3 million customers and with diverse business functions that rely on data from a multitude of source systems for critical operations, reporting, and strategic decision-making.
The Challenge
The bank's data was fragmented across numerous, disparate source systems, making it difficult to achieve a unified view for data. They needed a robust, centralized platform to streamline the management of large data volumes, enforce data quality, and provide reliable, business-ready insights for both internal MIS and regulatory reporting.
The Solution
Smart Analytica led the initiative to build a modern, centralized data platform through:
- Centralized Data Lake: Built an enterprise Data Lake on the Hadoop Cloudera Data platform to serve as the central repository for all data.
- Data Refinement and Curation: Leveraged PySpark to perform comprehensive data quality (DQ) checks, transformations, and standardization, creating a refined "Gold Layer" to act as the single source of truth.
- Business-Focused Data Marts: Developed tailored Data Marts for different business domains, specifically designed to support MIS and regulatory reporting requirements.
- Automated Data Ingestion: Utilized Sqoop to efficiently ingest high volumes of structured data from various source databases into the Data Lake.
