OLTP vs OLAP: Is the System Recording Transactions or Analyzing Them?

OLAP

Data warehouse

A warehouse consolidates information from multiple sources for analytical and reporting purposes and often stores historical data.

ETL

Extract, transform, load moves and standardizes data from source systems into an analytical environment.

The takeaway

OLTP records transactions. OLAP analyzes patterns. Data warehouses support broader analysis.
