A connection is a repository object that defines a connection in the domain configuration repository.
The Data Integration Service uses database connections to process jobs for the Developer tool and the Analyst tool. Jobs include mappings, data profiles, scorecards, and SQL data services.
You can create and manage connections in the Administrator tool, the Developer tool, and the Analyst tool.
The tasks that you can perform in each tool depend on the tool that you use. For example, you can create an SAP NetWeaver connection in the Developer tool and manage it in the Administrator tool, but you cannot create or manage it in the Analyst tool.
These connections are independent of the connections that you create in the PowerCenter Workflow Manager.
