Data Pipeline Architecture

Data Ingestion: Collect data from various sources
Data Processing: Transform and clean data
Data Storage: Store processed data efficiently
Data Serving: Provide data to ML models

ETL/ELT processes

Extract: Pull data from source systems
Transform: Clean and transform data
Load: Load data into target systems
Data Quality: Ensure data accuracy and completeness

Data Infrastructure

Data Lakes: Store raw data in native format
Data Warehouses: Store processed data for analytics
Data Marts: Store data for specific use cases
Streaming Platforms: Process real-time data

Data Governance

Data Lineage: Track data flow and transformations
Data Catalog: Metadata management
Access Control: Manage data access permissions
Compliance: Ensure regulatory compliance
