Zopstore Web App Built using Three Layered Architecture in Java Springboot

Abstract

Sprint boot is one of the popular Java frameworks to create reliable and scalable web applications.. The three tiered architecture of spring boot consists of a presentation/controller layer, a layer for managing business logic(service layer) and a Data Transport Object(DTO) layer. The job of the presentation layer is to take appropriate response bodies, query parameters and so on from the client(web app, web page etc.) and to send responses accompanied by appropriate headers and status codes. Data layer or DTO or Repository layer’s main task is to communicate with the database and perform one of the core functionalities like persisting an entity, reading from the database, updating and deleting entries from the database. Sitting between these two layers is the service layer. Service layer is responsible for handling business logic like validation, preparing responses and so on.
