The Gwallter Reece Chihuahua Sweater Co. (GRCCo) was established in 2013. It recently signed a large contract with PetCo pet stores. GRCCo will be required to track and forecast sweater sales. The technology that is used for communication between GRCCo and PetCo is

electronic data interchange.

Explanation:

Electronic data interchange is when different parties communicate electronically instead of writing on paper (for example purchase order and invoices).

There is provision for online transactions so that the parties involved will not have toake alternative arrangements.

Companies that do business electronically are called trading partners.

Electronic data interchange standardises the information communicated in such a way that the need for traditional paper is eliminated. The process change is dramatic.
