MOLAP

MOLAP (Multidimensional Online Analytical Processing) is an online analytical processing (OLAP) that indexes directly into a multidimensional database. It processes data that is already stored in a multidimensional collection in which all possible combinations of data are reflected and each of which can be accessed directly.

Advantages of MOLAP include:

• Effective data extraction
• Fast query performance due to optimized storage, multidimensional indexing, and caching
• Compact for low dimension data sets
• Smaller sized data collection due to its compression techniques
• Natural indexing due to array models
• Automated computation of higher level aggregates of data
