You can add connections to a broad array of services (data sources) in projects and catalogs. Source connections can only be used to read data; target connections can only be used to load (save) data. When you create a target connection, be sure to use credentials that have Write permission or you won't be able to save data to the target.
Not all connections are available for all Watson Studio and Watson Knowledge Catalog plans.
From a project, you must create a connection to a data source before you can read data from it or load data to it.
From a catalog, you must add a connection asset before you can add data assets for the tables you can access from the connection.
Note: This topic does not apply to streams flows. See Creating a connection in a streams flow.
