It is an ecommerce architecture that separates the front-end presentation layer of an online store from the back-end ecommerce functionality, allowing for greater flexibility, customization, and scalability. This way, the front-end design and user interface (UI) can be created separately from the platform and can be updated or changed without affecting the underlying ecommerce infrastructure. This enables retailers to create highly personalized, engaging, and interactive user experiences tailored to their customer's needs and preferences. At the same time, back-end ecommerce functionality, such as order management, inventory management, and payment processing, remains intact and can be accessed through an API (application programming interface), enabling seamless integration with third-party tools and services, making it easy to add new functionality, experiment with new technologies and adapt to changing market trends without disrupting the core ecommerce infrastructure.

The Homepage is the website's main page that usually contains information about the company, and serves as the gateway to the other pages. In the Online Store, this page is significant as it guides the user to help him find the products or services he wants to purchase.

Inventory is the stock of goods that an ecommerce retailer sells (or plans to sell in the future).
