The Banking Application is built using a microservices architecture, incorporating the Spring Boot framework along with other Spring technologies such as Spring Data JPA, Spring Cloud, and Spring Security, alongside tools like Maven for dependency management. These technologies play a crucial role in establishing essential components like Service Registry, API Gateway, and more.

Moreover, they enable us to develop independent microservices such as the user service for user management, the account service for account generation and other related functionalities, the fund transfer service for various transfer operations, and the transaction service for viewing transactions and facilitating withdrawals and deposits. These technologies not only streamline development but also enhance scalability and maintainability, ensuring a robust and efficient banking system.

• Service Registry: The microservices uses the discovery service for service registration and service discovery, this helps the microservices to discovery and communicate with other services, without needing to hardcode the endpoints while communicating with other microservices.

• API Gateway: This microservices uses the API gateway to centralize the API endpoint, where all the endpoints have common entry point to all the endpoints. The API Gateway also facilitates the Security inclusion where the Authorization and Authentication for the Application.

• Database per Microservice: Each of the microservice have there own dedicated database. Here for this application for all the microservices we are incorparating the MySQL database. This helps us to isolate each of the services from each other which facilitates each services to have their own data schemas and scale each of the database when required.

• 👤 User Service: The user microservice provides functionalities for user management. This includes user registration, updating user details, viewing user information, and accessing all accounts associated with the user. Additionally, this microservice handles user authentication and authorization processes.

• 💼 Account Service: The account microservice manages account-related APIs. It enables users to modify account details, view all accounts linked to the user profile, access transaction histories for each account, and supports the account closure process.

• 💸 Fund Transfer Service: The fund transfer microservice facilitates various fund transfer-related functionalities. Users can initiate fund transfers between different accounts, access detailed fund transfer records, and view specific details of any fund transfer transaction.

• 💳 Transactions Service: The transaction service offers a range of transaction-related services. Users can view transactions based on specific accounts or transaction reference IDs, as well as make deposits or withdrawals from their accounts.

To get started, follow these steps to run the application on your local application:

• Make sure you have Java 17 installed on your system. You can download it from the official Oracle website.
• Select an Integrated Development Environment (IDE) such as Eclipse, Spring Tool Suite, or IntelliJ IDEA. Configure the IDE according to your preferences.
• Clone the repository containing the microservices onto your local system using Git. Navigate to the directory where you have cloned the repository.
• Navigate to each microservice directory within the cloned repository and run the application. You can do this by using your IDE or running specific commands depending on the build tool used (e.g., Maven or Gradle).
• Set up Keycloak for authentication and authorization. Refer to the detailed configuration guide provided here for step-by-step instructions on configuring Keycloak for your microservices.
• Some microservices and APIs may depend on others being up and running. Ensure that all necessary microservices and APIs are up and functioning correctly to avoid any issues in the application workflow.

For a detailed guide on API endpoints and usage instructions, explore our comprehensive API Documentation. This centralized resource offers a holistic view of the entire banking application, making it easier to understand and interact with various services.

Explore the linked Java Documentation to delve into detailed information about classes, methods, and variables across all microservices. These resources are designed to empower developers by providing clear insights into the codebase and facilitating seamless development and maintenance tasks.

As part of our ongoing commitment to improving the banking application, we are planning several enhancements to enrich user experience and expand functionality:

• Implementing a robust notification system will keep users informed about important account activities, such as transaction updates, account statements, and security alerts. Integration with email and SMS will ensure timely and relevant communication.
• Adding deposit and investment functionalities will enable users to manage their savings and investments directly through the banking application. Features such as fixed deposits, recurring deposits, and investment portfolio tracking will empower users to make informed financial decisions.
• and more....
