I am a director at a business enhancement solutions company that provides mechanical systems and distributes high-quality bearings and related products.

I am planning for b2b e-commerce. I have operations in Singapore, Malaysia, Indonesia, China, and Mongolia. Each country uses a different ERP. Singapore HQ uses JDE (one world), that was last implemented 20 years ago.

I intend to consolidate the data to one 'location' for the integration of data into e-commerce or e-marketplace. Is a data warehouse the best way to go? 

Thanks! I appreciate your help.
