EFS Networks designed and deployed a generative AI data assistant that translates natural-language questions into SQL queries with enterprise-grade security:
- Amazon Bedrock (Claude 3 Instant) — Natural-language to SQL translation for intuitive data access
- Amazon Athena + Glue Catalog — Query execution and schema management across distributed data sources
- OpenSearch Serverless + Titan Embeddings — Semantic context and metadata grounding for accurate query interpretation
- QuickSight API — Automatic visual summary rendering from query results
- Amazon Verified Permissions — Row-level security enforcement per user role
- SageMaker Pipeline — Continuous learning through user feedback ingestion on query accuracy
