Retail Banking Transaction Processing

Group Category: Business Requirement

Product Category: Cloud & Data Engineering

Sub Category: Python & SQL for Data Engineering

Business Overview:

Retail banking systems generate large volumes of structured JSON transaction data. However, raw JSON files are not directly usable for reporting or analytics.

In this Business Requirement, learners analyze multiple banking JSON files, design a fully normalized PostgreSQL database, build an API-based ingestion system using FastAPI, and generate business summaries through a frontend UI.

This project simulates a real-world data engineering requirement — transforming hierarchical JSON into a scalable relational architecture with proper relationships, atomicity, and reporting capabilities.

Product Highlights:

JSON-to-Relational Database Design (1NF–3NF)
PostgreSQL schema creation with PK, FK & constraints
FastAPI-based data ingestion pipeline
Multi-file batch processing & tracking
File-wise and overall transaction summaries
Full-stack integration (Database + API + UI)

Learning Outcomes:

By completing this project, learners will be able to:

Analyze complex JSON structures
Design normalized PostgreSQL databases
Implement relational integrity and atomic data storage
Build REST APIs using FastAPI
Load and validate multi-file transactional data
Generate analytical summaries using SQL
Develop an end-to-end data engineering workflow
