HYBRID OLAP Meaning and
Definition
-
Hybrid OLAP, also known as HOLAP, is a data analysis technique that combines the benefits of both Relational OLAP (ROLAP) and Multidimensional OLAP (MOLAP) models. It aims to provide a balanced approach that addresses the limitations of each model and offers enhanced performance and flexibility in querying and analyzing large datasets.
In HOLAP, data is stored in both relational and multidimensional formats. Aggregated and summarized data is typically stored in a multidimensional database, while detailed or granular data is stored in a relational database. This approach allows users to efficiently handle large amounts of data while still providing fast query response times.
HOLAP provides the capability to perform both relational and multidimensional operations on data. It offers the flexibility of ROLAP by allowing users to access and analyze detailed data stored in the relational database. On the other hand, it also leverages the fast query processing and analytical capabilities of MOLAP for aggregated data stored in the multidimensional database.
This hybrid approach enables users to perform complex and ad-hoc queries that require both detailed and summarized data. It allows for the exploration and analysis of data from multiple perspectives, dimensions, and levels of granularity, while maintaining efficient performance.
Overall, HOLAP combines the strengths of ROLAP and MOLAP to provide users with a flexible, scalable, and efficient solution for analyzing and querying large datasets.

Etymology of HYBRID OLAP
The term "hybrid OLAP" does not have a specific etymology. It is a combination of two concepts: "hybrid" and "OLAP".
- "Hybrid" refers to something that is a combination of two or more different elements. In the context of technology or computing, a hybrid typically refers to a system or approach that combines multiple technologies or methodologies to achieve specific goals.
- "OLAP" stands for Online Analytical Processing. It is a technology used in data analysis and reporting to perform complex calculations and analysis on multidimensional data. OLAP allows users to analyze data from various perspectives and dimensions, enabling decision-making and business intelligence.
The term "hybrid OLAP" is used to describe a combination of different OLAP technologies or approaches.
