MOLAP: In this type of OLAP, a cube is aggregated from the relational data source (data warehouse). When these variables are tracked on a spreadsheet, they are set on axes (x and y) where each axis represents a logical grouping of variables in a category. Multidimensional OLAP (MOLAP) is a classical OLAP that facilitates data analysis by using a multidimensional data cube. OLAP is a specialized tool that creates a multidimensional view of data for the user to do the analysis. … Another popular scenario is the “What if” scenarios of OLAP software. Since they have been created based on multidimensional databases. This type of OLAP system offers scalability for managing large volumes of data, and even when the data is steadily increasing. It combines data by dividing data of database between relational and specialized storage. OLTP is a class of systems that supports or facilitates high transaction-oriented applications. 1.

Some of the top HOLAP is as follows: Now let’s go through the advantages that OLAP tools have in the domain of Business Intelligence. This video explores some of OLAP's history, and where this solution might be applicable. Large blocks of data is cut into smaller segments and the process is repeated until the correct level of detail is achieved for proper analysis. If we now click on our pivottable or pivotchart we will see a new menu in the ribbon called PivotTable Tools. Throughout this time, I saw an incredible demand for faster processing, at the same time as data volumes grew bigger. Data analysis is based on OLAP: pivoting, drilling, dicing and slicing provides capability to mine data on different data subsets and abstraction levels. Or  perhaps users are better served by a dynamic spreadsheet “delivery” system to achieve, for example, a collaborative budgeting and forecasting solution.
