WebAPI Web Access To Telemation
How It Works
Retrieved data is stored on the client in “reference sets,” identified by a “reference number” (Refno). This permits multiple data sets from multiple data requests to be held in client memory for use by client applications. Reusing a reference set resets its contents and stores only the results of the new request.
Files are identified by their File Definition name as stored in DBASE. Fields are named, and prior knowledge of the File Definitions (at least at this beta release) is required in order to use the WebApi routines (a routine called WebApiDescribeFields() will return a list of all named fields for a file; however, only returned lengths are described, not data type).
