Not that anyone ever forgets Walmart is a really big company, but every now and then a fresh reminder surfaces. That was the case this week with an announcement by Datacert, Inc., that Walmart had selected its Passport technology platform to help manage domestic legal processes and systems. Big companies that make a lot of money tend to get sued a lot, and in Walmart’s case the situation is magnified by the fact that it has more than two million employees interacting each week with 200 million customers in its 8,000 stores. Now the company has on its side a new technology provider in Datacert, which bills itself as the premier global provider of enterprise legal management solution.
