3. Database Structure
We used MySQL as our database backend. Our web service stores and retrieve data
from here. To have minimum functionality in our project we created two table on a
database “user” & “message”. One is for storing & verifying user information and other
is used to store & retrieve messages for users.

Web Service
Backbone of this project is web service behind it. Our web service is built using PHP /
MySQL. Our web service runs on Apace Web Server. Main parts of our service are
Authentication, Send, Receive & Transceiver.
Authentication – When a client tries to connect to service it verifies the
authenticity of the user by matching username & password stored in database.
After verifying this service returns an access token to the user.
Send – When an authenticated user sends a message this endpoint receives it &
store it in database.
Receive – When an authenticated client contacts this endpoint, it returns new
messages in database.
Transceiver – This endpoint is for sending & receiving at the same time. Our C
based client uses this endpoint for faster access.
4. C Based Client
Most important part of this project is to display the possibility of creating a fully
functional C based chatting client.
Our C client uses Socket & Thread. Socket helps in accessing internet; Thread helps in
sending & receiving message at the same time without blocking the standard input /
output stream. The main benefit of this C client is it can run on different platforms.
Desktop Client
Our desktop client is built using Electron which is a cross platform application builder.
Due to this our application can run on most of the popular operating systems out there.
5. Web Client
Our web client is built using HTML / CSS / JavaScript and it uses the web service for
authenticating, sending & receiving message.
Mobile Client
Interface for our mobile client looks symmetrical to our desktop & web interface. Since
our theme is responsive we can fit it into almost any size of display.
