Another relevant discussion.

Then there are several free online courses you can take advantage of here. Especially Creating a Caché Class Definition course.

Do you have a class for your data?

Save it as CSV and import with Data Import Wizard or from the terminal.

On the other note, if you use REST on 2016.1+ you can enable CORS support in a more organised way:

Class cors.REST Extends %CSP.REST
{
/// This parameter influences the CORS support. The default is an empty string meaning 'not specified'.
/// If set to true (1) then CORS processing is ON. If set to false (0) then CORS processing is OFF.
/// If left unset "" then the decision to process CORS is delegated to the setting on the URL map route.
Parameter HandleCorsRequest;    

XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>
<Route Url="/:test" Method="GET" Call="Test" Cors="true"/>
</Routes>
}

/// This is the CORS request handler. User should override this method in their subclass
/// if they don't want the default behavior
ClassMethod OnHandleCorsRequest(pUrl As %String) As %Status
{

    #; The default implementation is simply to dispatch to the
    #; default handler
    Quit ..HandleDefaultCorsRequest(pUrl)
}

}

Note, that if you're okay with HandleDefaultCorsRequest then you don't need to redefine  OnHandleCorsRequest method and need supply only HandleCorsRequest or Cors attribute on per path basis.

In some cases Access-Control-Allow-Origin: * is not a valid value, so I usually determine origin host and supply it:

Do %response.SetHeader("Access-Control-Allow-Origin",..GetOrigins())

And GetOrigins method:

/// Get Origin from %request object
ClassMethod GetOrigins() As %String
{
    set url = %request.GetCgiEnv("HTTP_REFERER")
    return $p(url,"/",1,3) // get http(s)://origin.com:port
}

Also, sometimes additional headers may be required, here's one of the more permissive sets:

Do %response.SetHeader("Access-Control-Allow-Origin",..GetOrigins())
Do %response.SetHeader("Access-Control-Allow-Credentials","true")
Do %response.SetHeader("Access-Control-Allow-Methods","GET, PUT, POST, DELETE, OPTIONS")
Do %response.SetHeader("Access-Control-Max-Age","10000")
Do %response.SetHeader("Access-Control-Allow-Headers","Content-Type, Authorization, Accept-Language, X-Requested-With")

Congratulations!

Why not use SFTP for that?

The following method shows how you can get a list of the files on a server, via SFTP:

Method SFTPDir(ftpserver, username, password) As %Status
{
    set ssh = ##class(%Net.SSH.Session).%New()
    do ssh.Connect(ftpserver)
    do ssh.AuthenticateWithUsername(username,password)
    do ssh.OpenSFTP(.sftp)
    do sftp.Dir(".",.files)
    set i=0
    while $data(files(i))
    {
        write $listget(files(i),1),!
        set i=i+1
        // set st = sftp.Get(files(i), "C:\Temp\myfile.ext")
    }
    quit $$$OK
}

To download file(s) uncomment the line. Documentation.

You have to have HealthShare.

SELECT
NON EMPTY %KPI("PluginDemo","HighScoreCount",,"%CONTEXT")
ON 1
FROM [PATIENTS]
%FILTER ([HOMED].[H1].[ZIP].&[32006],[HOMED].[H1].[ZIP].&[32006])

Or, with %OR:

SELECT
NON EMPTY %KPI("PluginDemo","HighScoreCount",,"%CONTEXT")
ON 1
FROM [PATIENTS]
%FILTER %OR({[HOMED].[H1].[ZIP].&[32006],[HOMED].[H1].[ZIP].&[32006]})

What's the query?

You'll need need to provide more information about your setup.

TCIP

Do you mean TCP? If so you can open TCP listener and parse incoming data from your GPS device. Documentation.

Not the best solution, but DeepSee filters by default have a search input, you can enter part of the filter value and only filter values that have it would be shown (after pressing enter).

If you want to propagate mappings across all namespaces you can create %All namespace and map there. All mappings into %All namespace are visible everywhere (except for samples and docbook) .
