Users of Oracle databases can specify connection strings: on the command line (as in: sqlplus scott/tiger@connection_string) via environment variables ($TWO_TASK in Unix-like environments; %TWO_TASK% in Microsoft Windows environments) in local configuration files (such as the default $ORACLE_HOME/network/admin.tnsnames.ora)
Connections are built by supplying an underlying driver or provider with a connection string, which is a way of addressing a specific database or server and instance as well as user authentication credentials (for example, Server=sql_box;Database=Common;User ID=uid;Pwd=password;).
