What does online analytical processing (OLAP) primarily do?

Online Analytical Processing (OLAP) primarily focuses on facilitating complex queries and analyzing business data for reporting and decision-making purposes. It allows users to perform multidimensional analysis of business data, enabling them to view it from different perspectives.

By calculating and summarizing vast amounts of data, OLAP tools provide insights that aid in identifying trends, patterns, and anomalies. These capabilities are essential for business intelligence applications where users expect quick and flexible access to data analysis. The strength of OLAP lies in its ability to quickly generate aggregated data that can be further dissected, allowing analysts to make data-driven decisions efficiently.

While other options may touch on aspects of data management or performance, they do not capture the core function of OLAP, which is centered on analytical processing and reporting rather than design, performance improvement, or data generation.
