NLP-to-SQL Interface for Enterprise Databases
Executive Summary
This demo demonstrates how natural language processing can bridge the gap between business users and complex enterprise databases, potentially reducing query time from hours to minutes while eliminating dependency on technical teams.
The Challenge
Non-technical business users struggle to query complex financial databases, leading to 2-hour delays for simple reports, dependency on IT teams, and missed opportunities for real-time decision making. Traditional SQL requires technical expertise that business analysts don't have.
Key Pain Points:
- • 2+ hour delays for simple database queries
- • Complete dependency on IT teams for data access
- • Missed opportunities for real-time decision making
- • Business users lack SQL expertise
The Solution
Built a natural language interface that translates plain English queries into SQL with 95% accuracy. The solution includes a React frontend for intuitive query input, OpenAI API integration for natural language processing, and a FastAPI backend that generates and executes SQL queries against PostgreSQL databases.
Technical Architecture:
- • AWS serverless cloud infrastructure for production deployment
- • OpenAI API integration for advanced NLP processing
- • PostgreSQL integration with enterprise security
- • Docker containerization for scalability
- • FastAPI backend for robust API management
- • React frontend with intuitive natural language input
Business Impact & Results
Demonstrates potential to reduce query time from 2 hours to 2 minutes, eliminate 80% of IT support tickets, and enable real-time business insights. The solution scales to handle enterprise-level database complexity while maintaining security and performance.
Cloud Infrastructure
The solution is built on AWS serverless cloud infrastructure with enterprise-grade security, scalability, and reliability. The architecture follows cloud-native best practices for production deployment.
AWS Services & Architecture:
- • AWS RDS: Managed PostgreSQL database with automated backups
- • AWS API Gateway: RESTful API management and rate limiting
- • AWS Lambda: Serverless functions for NLP processing
- • AWS CloudFront: Global CDN for frontend assets
- • AWS IAM: Fine-grained access control and security
DevOps & Deployment:
- • Infrastructure as Code: AWS CloudFormation for reproducible deployments
- • Monitoring: CloudWatch for performance and error tracking
Implementation Approach
The project was delivered using an agile methodology over 3 weeks, focusing on rapid prototyping and iterative development to validate the concept with stakeholders.
Development Phases:
- • Week 1: Core NLP engine and OpenAI integration
- • Week 2: AWS infrastructure setup and backend API
- • Week 3: Frontend interface, testing, and deployment
