Distinguishing OLAP from Transactional Systems It is essential to differentiate Online Analytical Processing from Online Transaction Processing (OLTP). Key Operations: Slice, Dice, and Pivot Users interact with OLAP cubes using specific operations that define its analytical power.
Variants and Implementation Models There are generally three main implementation models for Online Analytical Processing, each offering different balances of speed and data freshness: Model Description ROLAP Relies on relational databases and uses standard SQL queries, offering high data accuracy but potentially slower performance. Pivot: Rotating the cube to view data from different perspectives or hierarchies.

HOLAP A hybrid approach that combines the benefits of ROLAP and MOLAP for flexibility and performance. While OLTP systems handle day-to-day transaction data and operational tasks, OLAP focuses on strategic decision-making.
