For Tableau Bridge, use the same drivers as. RDBMS use cases include online transaction processing (OLTP) and online analytical processing (OLAP). An OLAP cube, also known as multidimensional cube or hypercube, is a data structure in SQL Server Analysis Services (SSAS) that is built, using OLAP databases, to allow near-instantaneous analysis of data. Firstly, a cube is a three dimensional object. Yes, that is the basic idea. No driver needed. Architecture: Requirements: What is OLAP? OLAP (for online analytical processing) is software for performing multidimensional analysis at high speeds on large volumes of data from a data warehouse, data mart, or some other unified, centralized data store. The result can be NULL. In contrast to an OLTP database, an OLAP database is designed to process large datasets quickly to answer questions about data. I’ve come across BigQuery (BQ) at work a few times recently - mostly in the context of our data engineering team enabling data analysts to ask questions of our data. Processes that benefit from materialized views include online analytical processing (OLAP) operations that require significant processing with predictable and repeated queries like those in from extract, transform, load (ETL) processes or business intelligence (BI) pipelines.
