Online bookstore system is a new, web-based product design to provide online bookselling.

While the web-based application is the main focus of the project, there is also a server- side component which will be responsible for database and synchronization services. And there should be a client-side smart phone application to provide necessary working information to drivers. The scope of the project encompasses both server- and client- side functionalities.

The diagram shown above demonstrates the interactions between the user and the system, including the system structure.
