OLAP stands for _________.

• A. Online Analytical Processing
• B. Online Analysis Processing
• C. On-Line Analytical Processing
• D. Offline Analytical Processing

Answer: (A)

OLAP stands for Online Analytical Processing. This term identifies a category of database technology designed for quick, multidimensional analysis of data in a data warehouse. The word Online highlights interactive, real-time querying rather than batch processing. Analytical emphasizes the focus on computing aggregates, trends, and insights across multiple dimensions like time, product, and geography. Processing indicates the set of operations used to shape data for analysis, such as roll-up, drill-down, slicing, and dicing. This capability is what enables fast, complex queries for decision-making, setting OLAP apart from online transaction processing, which is oriented toward routine data updates and transactions. The other options differ by using the wrong word (Analysis instead of Analytical), the wrong form of Online (On-Line vs Online), or by implying Offline Processing, which doesn’t match OLAP’s purpose of interactive analytical querying.
