# Difference Between Concepts and Metrics

## Difference Between Concepts and Metrics

While concepts and metrics share the same structural components, they serve distinct purposes in the semantic model:

**Concepts:**

* Represent business entities or objects (things)
* Focus on characteristics, properties, and relationships
* Answer "what" and "who" questions
* Typically have one record per business entity instance

**Metrics:**

* Represent business measurements and KPIs (values)
* Focus on quantification, aggregation, and trends
* Answer "how much," "how many," and "how well" questions
* Typically aggregate data across multiple records

Understanding this fundamental difference helps when designing your semantic model and deciding whether a particular business entity should be implemented as a concept or a metric.
