Power Pivot data table is a model which is made up of tables, data types, columns, and table relations. These data tables are constructed for holding the data for a business entity.
In Power BI, a Power Pivot data table refers to a table that has been imported into the Power Pivot data model. The Power Pivot data model is a feature within Power BI that allows users to create more complex data models by importing multiple tables from various sources and establishing relationships between them.
Power Pivot data tables are often used to store large volumes of data that may come from different sources or tables within a database. These tables can be loaded into Power BI for analysis, reporting, and visualization purposes.
Key characteristics of Power Pivot data tables include:
- Columnar storage: Power Pivot data tables store data in a columnar format, which enables efficient compression and fast query performance.
- Relationships: Tables within the Power Pivot data model can be related to each other based on common fields, allowing users to perform complex analyses across multiple tables.
- DAX calculations: Power Pivot data tables support the use of Data Analysis Expressions (DAX), a powerful formula language that allows users to create calculated columns, measures, and complex calculations based on the data in the tables.
Overall, Power Pivot data tables are a fundamental component of Power BI’s data modeling capabilities, enabling users to create rich and insightful reports and dashboards from their data.
