Modern Lightweight ETL with SQLite

Traditional ETL processes often require heavy infrastructure and complex tooling. With SQLite and surveilr, we can implement lightweight yet powerful data transformation pipelines that run anywhere.

The SQLite Advantage

SQLite provides a self-contained, serverless database engine that's perfect for: - Edge computing scenarios - Local-first applications - Portable data analysis - Compliance and audit trails

ELT vs ETL

The Extract-Load-Transform (ELT) pattern flips traditional ETL on its head: 1. **Extract**: Gather data from various sources 2. **Load**: Import raw data into SQLite 3. **Transform**: Use SQL views for on-demand transformation

Implementation with surveilr

surveilr's architecture makes ELT natural: - Resource surveillance captures raw data - SQL views define transformations - Results are queryable in real-time

Healthcare Use Case

For remote patient monitoring: - Ingest device data from multiple vendors - Normalize data formats with SQL views - Generate compliance reports on-demand
