What is OLAP?
On-line Analytical Processing (OLAP) is a category of software technology that authorizes managers, analysts, and executives to gain in-depth insights by accessing a wide variety of data generated from raw sources quickly to reflect the real dimensions of the organization as per the client’s understanding.
Business information is subjected to multidimensional analysis using OLAP, which also offers complex estimations, trend analysis, and advanced data modeling. The vital framework for intelligent solutions, which includes business performance management, planning, budgeting, forecasting, analysis, simulation models, knowledge discovery, financial documentation, and data warehouse reporting, is being quickly improved. OLAP enables ad-hoc analysis of records in various aspects, giving end-users the knowledge and understanding they need for informed decision-making.
Who uses OLAP and Why?
OLAP applications are considered for a variety of organizational functions:
Finance and Accounting:

There are two primary uses for OLAP cubes. First, a data model that is more intuitive to business users than a tabular model must be made available to them. This model is referred to as Dimensional Model. The second goal is to provide quick query responses, which are quite challenging to achieve with tabular models.
