What is the difference between OLTP and OLAP systems in data mining architecture?

OLTP handles transactional data; OLAP handles analytical queries on aggregated data.

OLTP (Online Transaction Processing) systems are optimized for high-frequency insert/update operations with strict ACID compliance, typically used in operational databases. OLAP (Online Analytical Processing) systems are optimized for complex queries, aggregations, and historical analysis. In data mining architectures, OLTP feeds raw data into ETL pipelines, which then populate OLAP data warehouses. OLAP supports multidimensional analysis using cubes, enabling fast pattern discovery and mining operations.
