Steps to connect a CRM system with MDM

Hi everybody,

I've got a problem here : I should build a connection between a CRM system and MDM (get the data in several tables in the CRM system, normalize them in MDM and then put them back in the CRM).

What would the steps I've got to do to achieve that ? Do I need XI between the two systems ? Do I have to map the tables before sending them in MDM (and how could I do that ?)

Thank you for all the help you can give me

Seb
