# Schema

Schema in AWS refers to the structure definition used within AWS EventBridge Schemas. It describes the format, properties, and data types of events, enabling applications to understand and validate event data. The DescribeSchemaResponse provides details about a specific schema, such as its name, version, and content. This helps developers integrate and process events consistently across services.
