title: Software as a service - Approach
body: <p>I have a desktop ERP application used by around 100 customers at different locations.Since its cumbersome to manage deployment and installation of such environment,i am planning to move this to web platform.I came accross this concept of software as service..I intend to go for this design approach...
  The challenge i face here is that all customers will have there own databases and i want to make single web application which can connect to all the databases based on some licensing mechanism...
  I am not quite sure how to do this.</p>
  
  <p>Feedback and suggestions on this are most welcome.</p>
