+- [Watermarking](/security/watermark) to track and trace data access patterns
+- [Complete audit logs](/security/audit-log) for compliance reporting and forensic analysis
 
 ## Database Change Automation
 
-Similar to how GitLab/GitHub streamlines the code delivery, Bytebase streamlines the database change deployment from the non-prod environment all the way to the prod environment. Bytebase also supports GitOps with [built-in VCS integration](/vcs-integration/overview) and custom CI integration via [API](/integrations/api/overview/).
+**Problem:** Manual database deployments cause delays, errors, and weekend emergencies.
+
+**Solution:** Bytebase automates the entire database change lifecycle with GitOps-style workflows, built-in rollback capabilities, automated testing, and seamless CI/CD integration.
+
+**Perfect for:** Engineering teams practicing continuous deployment who need database changes to match their code delivery speed.
+
+**Key outcomes:**
+- Deploy schema changes 10x faster with zero manual errors
+- Eliminate weekend deployments and emergency rollbacks
+- Achieve 99.9% deployment success rate with automated testing
+- Reduce database-related deployment delays by 90%
+
+**Key features:**
+- [VCS Integration](/vcs-integration/overview) for GitOps workflows

+
+## Multi-Database & Multi-Cloud Operations
+
+**Problem:** Managing PostgreSQL, MySQL, MongoDB, and Snowflake across AWS, GCP, and Azure creates operational chaos.
+
+**Solution:** Bytebase provides a single control plane for all your databases, regardless of type or location. Manage 100+ database instances as easily as one.
+
+**Perfect for:** Organizations with heterogeneous database environments or multi-cloud strategies.
+
+**Key outcomes:**

+- [20+ database types](/introduction/supported-databases) including SQL and NoSQL
+- Cross-cloud management (AWS RDS, GCP Cloud SQL, Azure Database)
+- Unified operations for OLTP and OLAP workloads
+- Consistent security policies across all databases
+
+## Multi-Tenant & Sharded Database Management
+
+**Problem:** Whether you have 1,000 tenant databases or 50 sharded partitions, deploying schema changes manually is error-prone, time-consuming, and risks data integrity.
+
+**Solution:** Bytebase treats multiple databases as a single logical unit, executing changes in parallel with automatic rollback on failure. Deploy to thousands of databases in minutes, not days.
 
-## Holistic Database Security
+**Perfect for:** B2B SaaS companies with database-per-tenant architecture and high-scale applications with horizontally partitioned data.
 
-Organizations want to limit database access and enforce approval flow to conform compliance and avoid data leaks. Bytebase provides a suite of features to support this:
+**Key outcomes:**
+- Deploy to 10,000 databases in under 1 hour (vs. days of manual work)
+- Achieve 100% consistency across all tenant databases
+- Reduce deployment errors by 95% with automated rollback
+- Scale database operations without scaling operations team
 
-- [Database Permission](/security/database-permission/overview)
-- [Dynamic Data Masking](/security/data-masking/overview)
-- [Watermark](/security/watermark)
-- [Audit Log](/security/audit-log)
+**Key features:**
+- [Batch operations](/change-database/batch-change/) with parallel execution
+- Automatic rollback on any failure
+- Zero-downtime migrations with health checks
+- Progress tracking and detailed execution logs
+- Tenant/shard-aware deployment strategies
 
-## Just-in-Time (JIT) Database Access
+## Schema Quality & Standardization
 
-You can grant temporary database permissions to the users when they need to troubleshoot. Users can self-request the permission via the Bytebase UI or it can be integrated into the existing GitOps flow.
+**Problem:** Inconsistent naming conventions and poor schema design lead to technical debt and production issues.
 
-## Multi-Database Management
+**Solution:** Enforce schema standards automatically with 100+ customizable SQL review rules. Catch issues before they reach production.
 
-Organizations normally have more than one database system for managing OLTP and OLAP workload. Bytebase supports all [mainstream databases](/introduction/supported-databases).
+**Perfect for:** Platform teams establishing engineering excellence standards.
 
-## Schema Enforcement
+**Key outcomes:**
+- Reduce schema-related incidents by 90%
+- Enforce consistent naming conventions across all teams
+- Prevent performance issues with automated detection of missing indexes and schema anti-patterns
+- Customize rules for different environments (stricter for production)
 
-Data quality and system robustness are largely determined by the database schema. And being able to enforce standards consistently is the key to a high-quality schema. Bytebase can enforce [100+ SQL Review rules](/sql-review/overview) including naming convention, anti-SQL pattern detections and etc. You can also configure each individual rule for prod and non-prod environments respectively.
+**Key features:**
+- [100+ SQL review rules](/sql-review/overview) with customizable enforcement
+- Automated detection of anti-patterns and performance issues
+- Environment-specific rule configurations
+- Integration with development workflows
 
-## Multi-Tenant Service
+## Platform Engineering & IDP Integration
 
-A SaaS service may provision separate databases for each of its tenants. It's painful and error-prone to make sure a database change is consistently applied to each individual tenant's database. Bytebase can [change databases from multiple tenants](/change-database/batch-change/#change-databases-from-multiple-tenants).
+**Problem:** Building database management capabilities into your Internal Development Platform requires months of engineering effort.
 
-## Partitioned Database
+**Solution:** Use Bytebase as a headless database platform via comprehensive APIs. Get enterprise database management without building it yourself.
 
-As data grows, databases and tables maybe partitioned into smaller chucks. Meanwhile, you still want to
-apply the same database change to all partitions since they share the same schema. It's painful and error-prone to make sure a database change is consistently applied to each partition. Bytebase can [batch change many databases in a consistent manner](/change-database/batch-change/#change-database-group).
+**Perfect for:** Platform teams building golden paths for developers.
 
-## Internal Development Platform (IDP)
+**Key outcomes:**
+- Reduce IDP development time from months to weeks
+- Provide developers with self-service database capabilities
+- Maintain centralized control while enabling team autonomy
+- Integrate seamlessly with existing developer workflows
 
-The Bytebase UI console is built on the [public API](/integrations/api/overview/). If you have your own IDP
-and want to integrate database capabilities, you can treat Bytebase as a headless backend and call the API.
+**Key features:**
+- [REST API](/integrations/api/overview/) for all operations
+- Webhook notifications for event-driven workflows
+- SSO integration with existing identity providers
+- Embeddable UI components for custom portals
