Data Model


1. About Data Model


In Microsoft Excel, a Data Model refers to a collection of tables and their relationships that can be used for more advanced data analysis.

It allows users to create relationships between tables, define calculated columns and measures, and leverage powerful features like PivotTables and PivotCharts.

The Data Model is available in Excel 2013 and later versions.


2. Key components and features of Data Models in Excel include:


  • Tables and Relationships:

    • Users can import multiple tables of data into the Data Model. These tables might come from different sources or represent various aspects of the same dataset.

    • Relationships can be established between tables based on common columns, allowing Excel to understand how the tables are related.

  • Calculated Columns:

    • Calculated columns can be added to tables within the Data Model. These columns contain formulas that derive values based on calculations performed on other columns.

  • Measures:

    • Measures are calculations that are applied to the entire dataset. They often involve aggregations, such as sums, averages, or other complex calculations. Measures are particularly useful in the context of PivotTables and PivotCharts.

  • PivotTables and PivotCharts:

    • With the Data Model, users can create more sophisticated PivotTables and PivotCharts that leverage the relationships, calculated columns, and measures. This allows for dynamic and interactive data analysis.

  • Data Analysis Expressions (DAX):

    • DAX is a formula language used within the Data Model for creating custom calculations and expressions. It is especially powerful for creating complex measures and calculated columns.

  • Importing External Data:

    • Users can import data from external sources directly into the Data Model, such as data from databases, online services, or other Excel workbooks.

Using a Data Model in Excel provides a more structured and powerful way to analyze large and complex datasets.It is particularly beneficial when working with multiple related tables and when advanced calculations and visualizations are required.The Data Model enhances Excel's capabilities for business intelligence and data analysis.
