Explanation
A datasource in Informatica (and in application servers generally) provides database connectivity through a pool of JDBC connections, improving performance by reusing connections. It does not provide information about servers (that is what the domain configuration does), establish thread connectivity (threads are managed by the server), nor bridge connectivity (bridge is a different concept).
