What is OLAP in SSAS?

An OLAP cube, also known as multidimensional cube or hypercube, is a data structure in SQL Server Analysis Services (SSAS) that is built, using OLAP databases, to allow near-instantaneous analysis of data. The topology of this system is shown in the following illustration.

What are the three types of OLAP server?

There are three main types of OLAP: MOLAP, HOLAP, and ROLAP. These categories are mainly distinguished by the data storage mode. For example, MOLAP is a multi-dimensional storage mode, while ROLAP is a relational mode of storage. HOLAP is a combination of multi-dimensional and relational elements.

In which architectural component does OLAP fit in what is the function of OLAP?

Answer. Online Analytical Processing (OLAP) is a category of software that allows users to analyze information from multiple database systems at the same time. These operations in relational databases are resource intensive. With OLAP data can be pre-calculated and pre-aggregated, making analysis faster.
