+title: Data export to S3 - database structure reference
+description: Reference guide for identifying which database tables to include when configuring data exports to S3.
+template: concept-topic-template
+last_updated: March 18, 2026
+---
+
+When requesting a data export to S3, you need to specify which database tables to include.
+
+If you know exactly which tables contain the data you need, you can request an export for just those specific tables. However, if you're unsure where certain data lives or need a complete picture of a business domain, this guide helps you identify all the relevant tables.
+
+## How Spryker stores data
+
+Spryker stores business data across multiple relational tables that together form logical domain aggregates. For example, an order is not stored in a single table but spread across tables for addresses, items, payments, shipments, and more.
+
+This guide organizes tables by business domain to help you:
+- Discover which tables are related to a specific domain.
+- Ensure you don't miss important data when exporting a complete domain.
+- Identify project-specific tables that extend standard Spryker tables.
+
+The tables are grouped into two categories:
+
+- **Standard tables**: The default Spryker tables for each domain, listed in [Standard tables by domain](#standard-tables-by-domain).
+- **Project-specific tables**: Custom tables your project may have added. See [Identify project-specific tables](#identify-project-specific-tables).
+
+## Standard tables by domain
+
+The following sections list the standard Spryker tables for common business domains. You can reference these lists or use them as a baseline when requesting an export.
+

+
+## Identify project-specific tables
+
+Your project may include custom tables that extend the standard Spryker domains. To ensure complete exports, identify these tables and include them alongside the standard tables.
+
+Run the following SQL query against your database to find tables related to a specific domain. Replace the table names in the `IN` clause with the base tables of your target domain.
+
+**Example for Order domain:**
+
+```sql
+(
+    -- Tables that reference order tables
+    SELECT DISTINCT kcu.TABLE_NAME AS table_name
+    FROM information_schema.KEY_COLUMN_USAGE kcu
+    WHERE kcu.REFERENCED_TABLE_SCHEMA = DATABASE()
+      AND kcu.REFERENCED_TABLE_NAME IN ('spy_sales_order', 'spy_sales_order_item')
+)
+UNION
+(
+    -- Tables referenced by order tables
+    SELECT DISTINCT kcu.REFERENCED_TABLE_NAME AS table_name
+    FROM information_schema.KEY_COLUMN_USAGE kcu
+    WHERE kcu.TABLE_SCHEMA = DATABASE()
+      AND kcu.TABLE_NAME IN ('spy_sales_order', 'spy_sales_order_item')
+      AND kcu.REFERENCED_TABLE_NAME IS NOT NULL
+)
+ORDER BY table_name;
+```
+
+Compare the query results with the standard tables list. Any tables not in the standard list are project-specific and should be included in your export request.
+
+This query also detects optional Spryker features that may be installed in your project but not listed in the standard tables, such as ECO module tables.
+
+## Next steps
+
+Once you have identified all required tables for your domain, [request an export setup](/docs/ca/dev/set-up-data-export-to-s3.html#request-an-export-setup) by submitting a support ticket with your table list.
