    WMI Scripting layer supports JScript, and Perl as well. The downside is
    that the support for WMI Scripting Objects is in wbemdisp.dll which resides
    on Windows OS's (for the most part). It connects to Windows Management
    Service on the target computer which only Windows has.

    As for ODBC adapter these might help you from older post:
