Project-level connections
You can reuse project-level artifacts in multiple projects. You use the Connections tab to define a new project-level connection and its actions or to select an existing project-level connection and its actions.
For example, you can define a project-level connection to a database that is used as a data source or target of multiple projects. A project-level action might be an SQL query and schema that multiple maps use to look up the same database data.
