UML Diagram & Case Diagram: Mobile Application System Design Project

This project provides a comprehensive system design for a mobile application, employing a variety of UML diagrams to illustrate different aspects of the system. The project begins with a system description, outlining the application's functionality, which allows therapists to register and manage their work. It then presents a use case diagram depicting the interactions between the therapist and the system. Following this, the project includes a flowchart that visualizes the overall flow of activities within the application. The core of the project consists of detailed use case and activity diagrams for key functionalities like login, user registration, registering autistic children, creating therapist classes, adding categories, and adding images. The project also covers database design, including normalization to ensure data integrity, an entity-relationship diagram (ERD) to represent the database structure, and a schematic diagram that illustrates the relationships between database entities. The project also includes a bibliography of relevant resources.

System Description:
The system is a mobile application that allows therapists to register and store their work.
The mobile application provides different screens for different functions. The application has
authentication and authorization policies inbuilt in it. The therapists have to register first in order
to login to the system application. The application provides the services like storing child details,
category details, creating classes and many more.
The system diagram is presented through UML diagrams like Use case and Activity
along with Data Models like ERD and Schematic Diagram. The system has many parts such as
category, class, therapist, child, image and more. The ERD shows how the database will store all
these data. The schematic diagram represents the child and parent relationship among the data
database entities. The use case diagram and activity diagram shows the interaction of the user
with the system through a dynamic graphical representation. On the other hand, the flowchart
shows overall flow of activities within the application.
