The Synthesized platform is your complete solution for database masking, synthetic data generation, and subsetting. Get privacy-compliant, realistic test data in minutes.

> **New to Synthesized?** Start with our [5-Minute Quick Start](https://docs.synthesized.io/tdk/latest/user_guide/010_get_started/quickstart) to see the platform in action.

## What is the Synthesized Platform?

The Synthesized platform provides a secure, privacy-preserving, tailored version of production data that can be used for many purposes:

- **Creating privacy-compliant replicas** of production data for development, testing, and data engineering
- **Generating large amounts of data** for performance testing and load testing
- **Subsetting production databases** into smaller, manageable datasets while maintaining referential integrity

The platform gives you the ability to generate structured synthetic test data at the database level, replicating database structures and maintaining key features like referential integrity whilst also preserving data privacy.

## How It Works

> **NOTE**
> Platform Workflow
>
> Source DB → Connect → Analyze → Transform → Write → Destination DB

The Synthesized platform connects to your source and destination databases, analyzes the schema and data patterns, then applies transformations according to your workflow configuration:

Transformation Pipeline

  
| Step | Action | Details |
| --- | --- | --- |
| 
**1\. Connect**

 | 

Connects to your source database and reads the schema

 | 

Secure connections via JDBC, supports all major databases

 |
| 

**2\. Analyze**

 | 

Understands data types, constraints, and relationships

 | 

Automatic schema detection, relationship mapping

 |
| 

**3\. Transform**

 | 

Applies masking, generation, or subsetting based on your workflow

 | 

Configurable transformers, maintains data integrity

 |
| 

**4\. Write**

 | 

Outputs transformed data to your destination database

 | 

Batch processing, optimized performance

 |

**What’s Preserved**

The platform maintains these critical elements from source to destination:

<table><tbody><tr><td class="hdlist1">Schema</td><td class="hdlist2"><p>Table and column names</p></td></tr><tr><td class="hdlist1">Data Types</td><td class="hdlist2"><p>All columns maintain their original data types</p></td></tr><tr><td class="hdlist1">DDL</td><td class="hdlist2"><p>Constraints, procedures, views, sequences</p></td></tr><tr><td class="hdlist1">Referential Integrity</td><td class="hdlist2"><p>Primary and Foreign keys</p></td></tr><tr><td class="hdlist1">Key Cardinality</td><td class="hdlist2"><p>Foreign key distributions</p></td></tr></tbody></table>
