A connection string stores the information required to connect to a database server. A connection string usually includes a DSN, as well as the user ID and password required to log in to the database server. This information varies depending on the particular database server. The 'Additional Connection String Parameters' feature of Strategy allows the user to specify additional connection string parameters manually.
