Hi Laxman v
Master Data Management is a general consept that you should learn. I don't know all the product you mentioned but Multidomain MDM is the product you should focus in my opinion. For expamle product 360 is special product for Product data management, it has different uı, diffrent tools but every thing on Product 360 can be done via Multidomain MDM. I think it will be a good choose Multidomain MDM to start learning general concepts.
