# Building Data Model

## Create Data Model

The video below guides you through the steps to **create a Data Model** and **set up Primary Keys** for the corresponding datasets.

## Set up Primary Keys

**A Primary Key** is essential for setting up **Relationships** within each Data Model.

## Establish Relationships

The video below walks through the steps to **create a Relationship** in a Data Model, assuming the Data Model has been created previously.

## Define Measures

**Measures** are created using aggregate functions (such as **SUM**, **COUNT**, etc.) that can be calculated from data.

FPT Data Suite supports **Basic Measures** (like SUM, AVG, MIN, MAX), and users can leverage these in the report-building process.

Additionally, users can create their own custom Measures for different, more complex calculations to meet specific reporting needs.

The video below walks you through the steps to **create a Measure** and test the newly created Measure.
