DSS

Hi all,

I am new to the forum, also new to BI. I have been working for marketing research agency for quite sometime now i am trying into BI. As i understand Market Intelligence, Business Intelligence and Competitive Intelligence are 3 major components in Decision Support System, i want to know is there real serious correlation among these components. what i am trying to understand here is how far these field contribute to DSS of any corporation. It can be evaluate better by understanding contribution by BI vs. MI and BI vs. CI and MI vs. CI.

i appreciate your help!
thanks,
