I want to get a free trial version for contact ondemand. I am aware of crm ondemand free trial version and used it. How to get one similar version for contact ondemand? what is the basic difference between crm ondemand and contact ondemand?
You can't get a trial version of Contact On Demand. You can get a demo from a partner - I could help you with that.
CRM On Demand and Contact On Demand are different applications with different uses. See the Oracle site.
