One of the issues with SAS for many IT departments is the lack of integration with service oriented architecture (SOA). The good news is with many new features coming online with versions 9.X+ are service oriented.
Lets look quickly at the Proc SOAP procedure now available.
For those SAS programmers out there that aren't familiar with SOAP or services, get your basis here: SOAPUser-Basics
In a nutshell, SOAP is transporting XML data via a HTTP Post. In order to make a successful SOAP call from SAS you need a couple of things.
1. a request XML file
2. a repsonse XML file
3. a webservice URL and WSDL (Web Service Definition Language) -Think webservice users manual
Here is a simple example of a SOAP call we use on a daily job.
filename rqst_xml 'some file system reference';
* Create the XML;
if first.records=1 then do;
put '<?xml version="1.0"?>
if last.records=1 then do;
filename rspns_xml 'some file system reference';
proc soap in=rqst_xml
Upon executing the call, you can read in the rspns_xml data with the SAS XML engine.
This is meant to be a simple example with very limited scope. Service architecture can quickly get complicated with error and condition handling. Please let us know if you need help with your SAS architecture or coding.
