Design and Implementation of E-commerce Website using Automata Theory

The current growth of technology has made a tremendous increase in the e-commerce industry. Internet-based e-commerce becomes the sole choice of a media to promote their industry as it offers most exciting business opportunities. This paper involves designing the backend structure of an e-commerce web-application. The method incorporated in this paper is a development of a prototype which is structured with flow chart tools, context diagram and data flow diagram. In the given structure, we take the user through the routes of creating a new user or login using automata theory concepts (push down automata to check if the user is already present or the password is wrong), choosing items via favorite categories, adding them to cart and placing orders. The design also includes the payment gateway structure as well as the return policy design (in which a pushdown automaton is used to work in reverse of the ‘order’ structure). A database could be incorporated which can maintain the input and output of the user and achieve uniqueness for the user. The challenges faced were brainstorming the simplest yet feasible and optimized structure of the backend of the architecture which is easy to understand for both the developers and users. We finally figured out that the best method is to have multiple databases for various tasks.
