To access your data in PostgreSQL, create a connection asset for it.
PostgreSQL is an open source and customizable object-relational database.
- PostgreSQL 8.2+
Create a connection to PostgreSQL
To create the connection asset, you need these connection details:
- Database name
- Hostname or IP Address
- Port number
- Username and password
- SSL certificate (if required by the database server)
For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.
Choose the method for creating a connection based on where you are in the platform
In a project Click Assets > New asset > Data access tools > Connection. See Adding a connection to a project.
In a catalog Click Add to catalog > Connection. See Adding a connection asset to a catalog.
In a deployment space Click Add to space > Connection. See Adding connections to a deployment space.
In the Platform assets catalog Click New connection. See Adding platform connections.
Next step: Add data assets from the connection
Where you can use this connection
You can use PostgreSQL connections in the following workspaces and tools:
- Cognos Dashboards (Watson Studio)
- Data Refinery (Watson Studio or Watson Knowledge Catalog)
- DataStage (DataStage service)
- Metadata import (Watson Knowledge Catalog)
- SPSS Modeler (Watson Studio)
- Platform assets catalog
- Other catalogs (Watson Knowledge Catalog)
