However, challenges exist:

• Complexity: Implementing these patterns can be technically demanding.
• Data Privacy: Ensuring compliance with data privacy regulations is crucial.
• Scalability: Systems must handle increasing data volumes without performance degradation.

Common Types

Several Data Integration Patterns are widely used:

1. ETL (Extract, Transform, Load): Extracts data from source systems, transforms it, and loads it into a destination system.
2. ELT (Extract, Load, Transform): Loads data into a destination system first, then transforms it.
3. Data Virtualization: Provides a unified data view without physical data movement.
4. Change Data Capture (CDC): Tracks changes in data sources and updates target systems accordingly.
5. Data Streaming: Processes data in real-time as it flows through the system.
6. API-Based Integration: Uses APIs to connect and integrate different systems.
7. Data Mesh: Decentralizes data ownership and management across domains.

The next sections will introduce these patterns one by one.
