Following table discusses some important parameters required during ODBC setup
Data Source Name: This field identifies the data source and you will see this in WinSQL's connection window.
Database: This is the most important information and is often mistyped by new users. Since we are using the SuperServer architecture, this field expects a host name, TCP/IP port, and the file name representing the database. The format of this string is HostName/Port:FileName . You can omit the TCP/IP port number if the server is listening on the default port, which is 3050. For file name you can either use UNIX style or Windows style separators.
Client: Leave this blank. This is only required for embedded servers.
Database Account: This is the login id. Try using SYSDBA, which is a pre-built account that comes with Firebird
Password: The default password for SYSDBA is masterkey
Role: Leave this blank, particularly if you are using the SYSDBA account.
