# 3. Connectors & workspace creation
To start working in Syntho, the first step is to connect your data sources and initialize your workspace.

### Supported databases

Missing a database connector? Let us know. Custom connectors can be built on request.

### Initialization modes overview
| Mode | When to use | What happens |
| ---------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- |
| Synthesize all | For one or more two related tables. To preserve maximum statistical validity with high privacy. | PII columns receive mock generator suggestions, and non-PII columns use AI synthesis. |
| Mock all | Theoretically the most secure, since all data is generated independently of the original data. This is also the best choice if there is no or limited input data available. | All PII and non-PII columns get one or more suggested mock generators. |
| Mock or mask all | Like “Mock all”, except masking generators may be applied in certain scenarios to generate more realistic data. | All PII and non-PII columns get one or more suggested mock and/or mask generators. |
| De-identify | When only replacement of PII is required, while non-PII columns should remain in-tact, making it suitable for internal test cases. | Suggested generators are applied only to PII columns. Non-PII columns do not receive any generator suggestions.. |
| From scratch | For custom configurations or when only a few tables need to be configured. | All tables start excluded by default, and the application doesn't suggest generators. |
