Apama and social data


I am interested in exploring the use of Apama combining business data and social data and would like to understand more about the social data sources which you integrate to/are available.

My questions are:

Is the social data real time only?
What sources of social data can be used?
Do you provide access to social data across multiple channels?
Which countries are covered in the social data you have access to?

What else can you tell me about the social data used by Apama?

thank you
