title: SOAP Server Application on Delphi XE8 communicate with SQL database
body: <p>I have created a SOAP Server Application on Delphi XE8. 
  I used it as a ISAPI SOAP service, with interface and implementation files. </p>
  
  <p>I deployed this service on IIS, and called it's functions from a VCL client. </p>
  
  <p>I am now trying to make a new function on the SOAP service that communicates with a MSSQL database on the SQL server.
  But every time i create a new Data module on the SOAP server, the service stops working. </p>
  
  <p>Can anyone please tell me how to make a database layer, then connect my SOAP service to it, to be able to call from other clients. </p>
  
  <p>Note : I am creating ISAPI.dll </p>
  
  <p>Thanks.</p>
