Databricks Certified Data Engineer - Associate

The data lakehouse architecture combines the best features of data lakes and data warehouses to simplify and unify siloed data architectures. Data lakehouses provide:

1. Data lake flexibility - Ability to store raw, semi-structured, and structured data
2. Data warehouse performance - ACID transactions, schema enforcement, and BI tool support
3. Unified platform - Eliminates the need for separate specialized systems for different use cases
4. Simplified architecture - Reduces data movement and duplication between siloed systems

Traditional data lakes and data warehouses alone are specialized for specific use cases and contribute to siloed architectures. The data lakehouse addresses this limitation by providing a unified platform that serves both analytics and data science workloads.
