What is OLAP, really? OLAP is an answer engine whose goal is to put the power of finding answers into the hands of non-technical individuals. It does this by grouping measures into logical groups and allowing the user to slice the data into different views through the use of dimensions.

An OLAP cube is a data structure that overcomes the limitations of relational databases by providing rapid analysis of data. Cubes can display and sum large amounts of data while also providing users with searchable access to any data points.

OLAP is an acronym for online analytical processing and cube refers to a multi-dimensional spreadsheet of data, so an OLAP cube is a staging platform for data analytics. Basically, a cube is a mechanism used to pull together data in organized, dimensional structures for analysis.

OLAP stands for Online Analytical Processing Server. It is a software technology that allows users to analyze information from multiple database systems at the same time. It is based on multidimensional data model and allows the user to query on multi-dimensional data (eg. Delhi -> 2018 -> Sales data).

A data cube refers is a three-dimensional (3D) (or higher) range of values that are generally used to explain the time sequence of an image’s data. It is a data abstraction to evaluate aggregated data from a variety of viewpoints. As such, data cubes can go far beyond 3-D to include many more dimensions.

In data warehousing, the data cubes are n-dimensional. For example, the 4-D cuboid in the figure is the base cuboid for the given time, item, location, and supplier dimensions. Figure is shown a 4-D data cube representation of sales data, according to the dimensions time, item, location, and supplier.

Limitations of OLAP cubes Vendors offer a variety of OLAP products that can be grouped into three categories: multidimensional OLAP (MOLAP), relational OLAP (ROLAP), and hybrid OLAP (HOLAP). Here is a breakdown of the differences between them.

OLAP cubes are used for the anyalysis of large volumes of disparate data sets. They let you do comparative analyses across multiple dimensions quickly and intuitively (if well designed) through large sets of data that may only be partially related.

Pre-modeling as a must. Regarding the business data,the traditional OLAP tools do not allow for the immediate analysis without pre-modeling.

There are three reasons to use an OLAP cube in addition to your relational database – performance, drill-down functionality and availability of software tools .

How to create cube files for offline use using Excel You need to first create or open a PivotTable or PivotChart report which is connected to SSAS cube. In PivotTable Tools section ,under Options click OLAP Tools dropdown and then Offline OLAP as shown in the image below. Click on create offline data file button as shown in the image below.
