ROLAP operates on relational databases, offering detailed data analysis and flexibility. MOLAP uses multidimensional databases for faster data retrieval and aggregation.
ROLAP vs. MOLAP

Key Differences

ROLAP (Relational Online Analytical Processing) works directly with relational databases, making it ideal for complex queries over large data volumes. In contrast, MOLAP (Multidimensional Online Analytical Processing) excels in summarizing data, thanks to its storage in multidimensional cubes.
