• Admin

Admin services:

• View transaction history of a particular client.
• View account balance of a particular client.
• Get account number of a particular client.
• View Bank dataBase
• Create a client account .
• Update a client account data.
• Delete client account.

User services:

• View transaction history of a particular client.
• View account balance of a particular client.
• Get account number of a particular client.
• Make a transaction either a deposit or a withdrawal.
• Make a transfer from one account to another.

you can log in to the system either as a regular user or as an admin.

System Details

Server Application :

• multithreaded server capable of handling multiple requests concurrently.
• Singleton pattern used to create the Database.
• Global mutex shared among all the threads to prevent data race over the Data base .

Client Application:

• Gui application.
• Separate thread for the logic .
• Observer pattern applied between the gui and the logic component.
• Singleton pattern used to create the application.
• Each functionality provided by the gui is implemented in a separate class which complies the single responsibility principle.

System Architecture:

• the system is designed based on the MVC pattern ( Model View control).
• Platform independent since it's designed using Qt framework.
• OOP principles are applied.
• Single responsibility principle is applied where each user request is implemented as a singlet class.
• singleton, observer design patterns applied.

To use the system :

• you should have a Linux distro and Qt framework installed
• Many distributions have a working FUSE setup out-of-the-box. However if it is not working for you, you may need to install and configure FUSE manually.

For example, on Ubuntu (>= 22.04):

sudo add-apt-repository universe
sudo apt install libfuse2

• Download the client image and the server image in the deployed file
• Give them execution permission
• Run each of the executables.
