Question

OLAP is

a. a tool that enables users to view the same data in different ways using multiple dimensions.
b. a tool to store object data in a database.
c. a online learning algorithm.
d. a protocol for reliable transmission on the Internet.

Answer 1

OLAP, or Online Analytical Processing, is a tool used in business intelligence to allow users to analyze data from multiple perspectives by organizing it into multiple dimensions.

Step-by-step explanation:

OLAP stands for Online Analytical Processing. It is a tool that enables users to view the same data in different ways using multiple dimensions. OLAP systems are useful in complex analytical and ad-hoc queries, primarily in the area of business intelligence. These tools facilitate the organization of data into multiple dimensions, enhancing data analysis and interpretation. Techniques related to OLAP include, but are not limited to, eigen-based principal components analysis (PCA), correspondence analysis (CA), and distance-based multidimensional scaling (MDS). Although these techniques are distinct from OLAP, they share a similar underlying goal of reducing complexity and summarizing data effectively.
