Data Flow Diagram of Online Chat Application
A Data Flow Diagram (DFD) for an online chat application illustrates the flow of data within the system, including how data moves between processes, entities, and data stores. Here’s a simplified DFD for an online chat application:
- Processes, represented by circles or ovals.
- Data stores, depicted by rectangles, represent where information is stored.
- Data flows, indicated by arrows, showcase how data moves between processes, data stores, and external entities.
- Let’s draw an Data Flow Diagram of Online Chat Application:
4.4.1 Software Requirements:
This software package is developed using html , react for front end . Node.js and MongoDB Server as the back end to store the database for backend .
- Operating System: Windows 7, 8, 9, 10 .
- Frontend: Html , Css , Javascript, react.js.
- Backend: Node.js, Express.js
- Database: MongoDBServer (back end)
4.4.2 Hardware Requirements:
- Processor: Intel core i3 or above for a stable experience and fast retrieval of data.
- Hard Disk: 40GB and above
- RAM: 256 MB or more, recommended 2 GB for fast reading and writing capabilities which will result in better performance time.
Online Chat Application Project in Software Development
Online chat application is one of the most common software development projects to date. In this article, we are going to make the Online chat application software development project from scratch, college students. We will be covering all the steps you have to do while developing this project.
