ROLAP stands for Relational Online Analytical Processing. ROLAP is an alternative to the MOLAP technology. While both ROLAP and MOLAP analytic tools are designed to allow analysis of data through the use of a multidimensional data model, ROLAP differs significantly in that it does not require the pre-computation and storage of information.

  • ROLAP stands for Relational Online Analytical Processing. ROLAP is an alternative to the MOLAP technology. While both ROLAP and MOLAP analytic tools are designed to allow analysis of data through the use of a multidimensional data model, ROLAP differs significantly in that it does not require the pre-computation and storage of information. Instead, ROLAP tools access the data in a relational database and generate SQL queries to calculate information at the appropriate level when an end user requests it. With ROLAP, it is possible to create additional database tables (summary tables or aggregations) which summarize the data at any desired combination of dimensions. While ROLAP uses a relational database source, generally the database must be carefully designed for ROLAP use. A database which was designed for OLTP will not function well as a ROLAP database. Therefore, ROLAP still involves creating an additional copy of the data. However, since it is a database, a variety of technologies can be used to populate the database. == ROLAP vs. MOLAP
  • ROLAP significa Procesamiento Analítico OnLine Relacional, es decir, se trata de sistemas y herramientas OLAP (Procesamiento Analítico OnLine) construidos sobre una base de datos relacional. Es una alternativa a la tecnología MOLAP que se construye sobre bases de datos multidimensionales. Ambos tipos de herramientas, tanto ROLAP como MOLAP, están diseñadas para realizar análisis de datos a través del uso de modelos de datos multidimensionales, aunque en el caso de ROLAP estos modelos no se implementan sobre un sistema multidimensional, sino sobre un sistema relacional clásico.
