relational OLAP (ROLAP) [ROLAP]

Share This

“Data for OLAP and hyper cubes is stored in relational database tables. The approach is often simpler to configure than MOLAP, but it requires computing subtotals on the fly for all queries. Most systems that use ROLAP include tools to pre-build some subtotals, such as Oracle’s materialized views.”
