What and how does online analytical processing work?

Data is gathered from several places and kept in one data warehouse from where it gets divided into data cubes for better analyses. 

The diversion of data is made in OLAP cubes on biases of various factors like the product category, geographical location, time duration, sales, and price list. 

Each dimension is filled with customer information, including the name, email address, delivery address, country, mobile numbers, purchase history, and other necessary details. 

The online analytical processing can perform several operations that include the following. 

  • Pivot: By rotating the axes of the cube, you can get a different view of data 
  • Slice: It allows the analyst to segregate and display certain information that they want to monitor. So, for example, if the analyst wants to see the sales performance in Mumbai from 2018 to 2019, the slice operation will enable them to display detailed information. 
  • Roll-up: This operation allows the analyst to consolidate the data along the required dimension. 
  • Dice: The operation that allows us to select data from multiple dimensions and evaluate the data. For example, if you want to fetch data of a particular date and a fixed geographical location, this feature will bring data and complete the analyses. 
  •  Drill-down: When the analyst wants to dig in-deep data, they use the drill-down operation to fetch minute details.
