Re-explain
ElasticSearch Relational Database
Document-oriented (JSON) Table-based (rows/columns)
Schema-flexible Fixed schema
Horizontal scaling Vertical scaling (primarily)
Near real-time search ACID transactions
Denormalized data Normalized data with JOINs
RESTful API SQL queries
Optimized for read-heavy workloads Balanced read/write operations

ElasticSearch excels at search, analytics, and handling unstructured data, while traditional databases are better for transactional operations requiring ACID properties.
