Hvad betyder ovenstående helt præcist?

Koden ser ud som følger:

<%
Set connection = Server.CreateObject ("ADODB.Connection")
DSN = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath ("/mdb_files/data/db.mdb")

Function openConn()
    connection.Open DSN
End Function

Function closeConn()
    connection.Close
End Function
%>
