OLAP is a software that performs multidimensional analysis with great speed on vast volumes of essential data from a data mart, data warehouse, or some other centralized and unified data store. 

However, on the other hand, Azure is a platform for public cloud computing, which includes the solutions like Platform as a Service, Infrastructure as a Service, and Software as a Service that can be used for the tasks like virtual computing, analytics, networking, storage, etc. So, let us discuss what Azure OLAP is and why it is used by top businesses.

What is OLAP or online analytical processing?

OLAP is a specific technology that can organize large business databases and also helps in complex analysis procedures. This technology can be used to perform several analytical queries that are complex without negatively affecting the transactional systems.

The databases used by a business to store all the essential documents and transactions are known as online transaction processing or OLTP databases. These databases have records that can be entered at a time. 

However, the databases that are used for OLTP were not developed for analysis. Hence, retrieving the required answers from those databases becomes a process that needs a reasonable amount of time and effort.

The OLAP systems were created to help extract information regarding business intelligence from the data in a highly performable way. This is possible because the OLAP databases are usually designed and optimized for low write and heavy read workloads.

What is Azure OLAP or OLAP in Azure?

In Azure, the vital data is held in OLTP. The flow of data to OLAP from OLTP is usually orchestrated with the help of SQL Server Integration Services. This can be executed quickly with the support of Azure Data Factory.

In Azure, the data stores that will meet the core needs for OLAP are:

  • Azure Analysis Services.
  • SQL server and Column Store Indexes
  • SSAS or SQL Server Analysis Services.
