DATA LAKE VS DATA-WAREHOUSING

– These are vast repositories that store raw data in its native format, without any predefined structure. – They offer flexibility in storing structured, semi-structured, and unstructured data. – Data lakes can scale horizontally to accommodate petabytes of data. – Ideal for exploratory analysis, big data processing, and machine learning initiatives.

DATA LAKE

– They are structured repositories that store processed and organized data from various sources. – Data warehouses use a schema-on-write approach, where data is organized into predefined structures. – They optimize for fast query performance by pre-aggregating data. – Suitable for business intelligence, reporting, and analytics applications.

DATA WAREHOUSE

– Data lakes store raw data in its native format, while data warehouses store processed and structured data. – Data lakes offer schema-on-read flexibility, whereas data warehouses enforce a schema-on-write approach. – Data warehouses are optimized for fast query performance, while data lakes may require additional processing for analysis.

KEY DIFFERENCES
