The original title is "OLTP vs OLAP : Understanding the Foundation of Modern Data Systems"

Short summary

OLTP and OLAP are two complementary database paradigms serving distinct business needs. OLTP systems (PostgreSQL, MySQL) handle fast, high-volume day-to-day transactions with normalized, row-oriented storage and ACID guarantees. OLAP systems (Snowflake, BigQuery) process complex analytical queries over large historical datasets using denormalized, columnar storage, with data flowing between the two via ETL/ELT pipelines.

• •OLTP handles fast transactional workloads with row-oriented, normalized schemas and ACID compliance
• •OLAP handles complex analytical queries over historical data using columnar, denormalized schemas
• •Data flows from OLTP to OLAP via ETL/ELT pipelines to support reporting without impacting operational performance
