End-to-end mastery: Datavid's application development expertise

Full stack development involves working on both the front-end (user interface) and back-end (server and database) aspects of software development, covering the entire technology stack of a web application.

The three layers of full stack development are:
1) Presentation Layer (Front-End): This layer focuses on the user interface and how the application is presented to users in their web browsers or mobile devices.
2) Logic Layer (Back-End): This layer contains the application's business logic, server, and database management, handling data processing and communication between the front-end and back-end.
3) Data Layer: This layer deals with data storage, retrieval, and management, often involving databases and other data storage solutions.

An e-commerce (e.g., Amazon) is an example of a full stack development application. It includes a front-end for product listings and user interfaces, a back-end for processing orders, managing inventory, and handling payments, and a data layer for storing product information and user accounts.
