To access your data in MariaDB, create a connection asset for it.
MariaDB is an open source relational database. You can use the MariaDB connection to connect to either a MariaDB server or to a Microsoft Azure Database for MariaDB service in the cloud.
- MariaDB server: 10.5.5
- Microsoft Azure Database for MariaDB: 10.3
Create a connection to MariaDB
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 MariaDB connections in the following workspaces and tools:
- Data Refinery (Watson Studio or IBM Knowledge Catalog)
- DataStage (DataStage service). See Connecting to a data source in DataStage.
- Decision Optimization (Watson Studio and Watson Machine Learning)
- Metadata enrichment (IBM Knowledge Catalog)
- Metadata import (IBM Knowledge Catalog)
- SPSS Modeler (Watson Studio)
Platform assets catalog
Other catalogs (IBM Knowledge Catalog)
- Watson Query service
- You can connect to this data source from Watson Query.
Setup depends on whether you are connecting from a local MariaDB server or a Microsoft Azure Database for MariaDB database service in the cloud.
