// Open opens a database specified by its database driver name and a

// database name and connection information.
//
// Most users will open a database via a driver-specific connection
// helper function that returns a *DB. No database drivers are included
// in the Go standard library. See https://golang.org/s/sqldrivers for
// a list of third-party drivers.
//
// Open may just validate its arguments without creating a connection
// to the database. To verify that the data source name is valid, call
// Ping.
// The returned DB is safe for concurrent use by multiple goroutines
// and maintains its own pool of idle connections. Thus, the Open
// function should be called just once. It is rarely necessary to
// close a DB.
