Using a connection profile
The connection profile includes information about the database driver, a user ID, password, port, host, and other properties related to the type of data source. BIRT supports using a connection profile when creating a data source in a report design. When a connection profile changes, the BIRT report picks up those changes. This behavior makes migration from a test to a production environment straightforward.
You can use connection profiles for all data source types, except SQL Query Builder data sources. If you have to use connection profiles for this type of data source, you must define a unique connection profile in each report.
