As Ryan mentioned in his post, SalesLogix offers the IDataService class that allows you to retrieve information about the underlying data connection.  The class also allows you to fetch a connection to the underlying data source as well and then execute commands directly to the data source rather than going through the provider. 

I wanted to talk about the attributes you can retrieve from the IDataService.  There are four properties you can retrieve.  These include:

• Server
• VenderVersion (Even though misspelled but this is the correct property)
• Alias
• Database

Each of these attributes can be accessed the same way, by instantiating the IDataService object and then calling the property, like so:

Sage.Platform.Data.IDataService datasvc = Sage.Platform.Application.ApplicationContext.Current.Services.Get<Sage.Platform.Data.IDataService>() as Sage.Platform.Data.IDataService;
    string alias = datasvc.Alias;
    string server = datasvc.Server;
    string version = datasvc.VenderVersion;
    string db = datasvc.Database;
    throw new Sage.Platform.Application.ValidationException("Alias: " + alias + "<br> Server: " + server + "<br> DB: " + db + "<br> Version: " + version);

This returns the following type of information:

7.5.3 Change

In addition to the above described properties (which all exist in 7.5.2)  SalesLogix 7.5.3 also introduces the property "Port".
