What is the primary function of the business layer in e-commerce?

The primary function of the business layer in e-commerce encompasses all exchanges between buyers and sellers, making it essential for the overall operation of e-commerce systems. This layer is integral in coordinating the activities that allow transactions to occur, including the management of inventory, product information, and customer orders. By addressing the dynamics of supply and demand, the business layer ensures that the marketplace functions smoothly, effectively supporting the interactions between the two main parties involved in e-commerce: buyers seeking products and sellers offering them.

This role serves as the foundation for various processes that include listing products, managing pricing, and facilitating the logistics involved in transactions. While the business layer does touch upon aspects of communication, financial transactions, and marketing strategies, its defining characteristic is the comprehensive management of all exchanges related to buying and selling, which is crucial for facilitating commerce in a digital environment.
