# ExecutionSchema

The ExecutionSchema is essential for organizing the execution flow in a program. 

When you call the **\_\_or\_\_** method of [**Component**](/core/component.md), it binds components in the [**ExecutionSchema**](/structural-components/executionschema.md) to create the execution pipeline. However, if you call **\_\_or\_\_** on the [**ExecutionSchema** ](/structural-components/executionschema.md)directly, a [**Component**](/core/component.md) is added to the schema. To maintain the ExecutionSchema's context, it's needed to wrap it within another Component, like another [**ExecutionSchema**](/structural-components/executionschema.md) or an [**Evaluator**](/core/evaluator.md).
