OLTP vs. OLAP: Know the Difference
By Shumaila Saeed || Published on February 3, 2024
OLTP (Online Transaction Processing) handles real-time database transactions; OLAP (Online Analytical Processing) is used for complex data analysis.
Key Differences
OLTP systems are designed to manage transactional data and are optimized for real-time operational tasks. OLAP, on the other hand, is geared towards complex queries and data analysis, working with historical data.

OLTP databases are structured for fast, reliable, and efficient transaction processing, typically involving insertions, updates, and deletions. In contrast, OLAP systems are optimized for reading and analyzing large volumes of data.
