+title: Database Group
+---
+
+
+
+Database groups are a powerful feature in Bytebase that allow you to manage collections of databases as a single unit. This simplifies operations when you need to apply consistent changes or run queries across multiple databases with similar structures.
+
+## Overview
+
+A database group is a logical collection of databases that share common characteristics. Instead of selecting databases individually for each operation, you can define a group once and reuse it for batch operations.
+
+Database groups are particularly useful in the following scenarios:
+
+- **Multi-Tenant SaaS Applications**: Software as a Service providers often maintain separate database instances for each customer or tenant. Database groups enable you to apply updates across all tenant databases simultaneously while maintaining isolation.
+
+- **Geographic Distribution**: Organizations operating across multiple regions (US, EU, AP) often deploy separate database instances for compliance, latency, or data sovereignty requirements. Groups help manage these regional deployments efficiently.
+
+- **Database Sharding**: For applications using horizontal partitioning, database groups simplify managing sharded databases by treating all shards as a cohesive unit during schema migrations.
+
+## Creating a Database Group
+
+### Prerequisites
+- You must have appropriate project permissions
+- Target databases should already be added to your Bytebase project
+
+### Steps
+
+1. **Navigate to Database Groups**
+
+ Within your project, click **Database > Groups** in the left sidebar.
+
+ 
+
+2. **Create New Group**
+
+ Click **New database group** to open the creation dialog.
+
+3. **Configure Group Settings**
+
+ - **Name**: Provide a descriptive name for your database group
+ - **Description** (optional): Add details about the group's purpose
+ - **Database Selection Rules**: Define criteria to automatically include databases
+
+ 
+
+### Database Selection Methods
+
+#### Basic Filtering
+Select databases based on:
+- Environment (Development, Staging, Production)
+- Instance location
+- Database name patterns
+
+#### Advanced Filtering with Labels
+For more complex scenarios, use database labels with raw expressions:
+
+```
+Where resource.labels.YOUR_LABEL_KEY == "YOUR_LABEL_VALUE"
+and has(resource.labels.YOUR_LABEL_KEY)
+```
+
+**Example expressions:**
+- Filter by tenant: `Where resource.labels.tenant == "enterprise" and has(resource.labels.tenant)`
+- Filter by region: `Where resource.labels.region == "us-west" and has(resource.labels.region)`
+- Combine multiple labels: `Where resource.labels.tier == "premium" and resource.labels.region == "eu" and has(resource.labels.tier) and has(resource.labels.region)`
+
+4. **Save the Configuration**
+
+ Click **Save** to create the group. The new group will appear in your database groups list and be available for batch operations.
+
+## Managing Database Groups
+
+### Editing Groups
+To modify an existing group:
+1. Navigate to **Database > Groups**
+2. Click on the group name
+3. Update the configuration as needed
+4. Save your changes
+
+### Deleting Groups
+To remove a database group:
+1. Navigate to **Database > Groups**
+2. Click the delete icon next to the group
+3. Confirm the deletion
+
+**Note**: Deleting a group does not affect the underlying databases; it only removes the grouping configuration.

-If you always change a fixed set of databases together, you can pre-define a `database group` to enclose those databases. Typical scenarios of using database group are:
+Database groups allow you to manage and batch change multiple databases together. This is particularly useful for SaaS multi-tenant architectures, geographic deployments, or database partitioning scenarios.
-- A Software as a Service (SaaS) provider provides separate database instances for each of its customers (aka. tenants) alongside their application deployments.
-- For compliance and performance reasons, companies provision separate database instances in US, EU, AP respectively.
