In order to create and execute a workflow, users needs to define the input and output (destination) data sources.

## Creating a Data Source

Data sources can be created via the data sources page. There are two ways to access this page:

![data sources](https://docs.synthesized.io/tdk/latest/user_guide/_images/data_sources.png)

- Data source page > create a data source

![data source](https://docs.synthesized.io/tdk/latest/user_guide/_images/data_source.png)

- Workflow page > list of data sources > [create a data source](https://docs.synthesized.io/tdk/latest/user_guide/010_get_started/workflow)

To create a new data source, the user are to enter the following parameters:

- Data source name (required)
- DB Type (required)

### Supported Data Sources

Synthesized easily connects to a variety of data sources.

**POSTGRES** **ORACLE** **MYSQL** **SQLITE** **MSSQL** **Snowflake** **DB2 LUW** **CSV** **XML** **SAP HANA**

- JDBC URL (needed, starting with `jdbc:[…​]` depending on type and driver)
- Authentication type:
  
  - Username & password (default)
  - No authentication
- Authentication details (depending on auth type)
- Permissions (private by default) \[explained below\]

## Data Source Permissions

Given the sensitive nature of data sources, each data source has its own access levels that is set when creating it.

Possible access levels are:

- Private (default): Only the data source creator, and users with administrator or owner roles can see it.
- Read-only: All users with “read data source” permissions can see it, but it can only be selected as a source (input) data source when creating a workflow
- Read & Write: The data source can be used as a source and as a destination in a workflow.
