Developers, if you utilize multiple database servers and have a hard time remembering the exact connection string to make connections (OLEDB, ODBC, DSN, etc.), then take a look at ConnectionStrings.com.

This is a straight to the point site which has information only about the connection strings required for dozens of data sources. Everything from SQL Server to Exchange to MySQL and SQLite is covered in a very logical and quick to access style.

Definitely a bookmark worthy site for any developer.
