Core Concepts & Terminology

The faizanGeek/ClaimProcessingSystem is designed to manage the lifecycle of claims efficiently and securely. This section introduces the fundamental concepts and terminology essential for understanding how the system operates and interacts with users and other components.

Core Concepts & Terminology

Understanding these core concepts will provide a solid foundation for interacting with and extending the Claim Processing System.

1. Claim

A Claim is the central entity within the system, representing a formal request for payment or benefit, typically submitted by a User. Each claim has a unique identifier and progresses through various stages, tracked by its Claim Status.

• Key Attributes:
  • Claim ID: A unique identifier for the claim.
  • User ID: The identifier of the user who submitted the claim.
  • Claim Date: The date when the claim was submitted.
  • Claim Amount: The monetary value associated with the claim.
  • Claim Type: Categorization of the claim (e.g., medical, insurance, expense).
  • Claim Status: The current state of the claim in its lifecycle.

2. User

A User is any individual or system interacting with the Claim Processing System. Users can submit, view, and manage claims, and their permissions are often tied to their assigned Role. The system supports user registration, login, and profile management.

• Key Attributes:
  • User ID: A unique identifier for the user.
  • Username: A unique name used for login.
  • Email: The user's contact email address.
  • Role: Defines the user's permissions and access level within the system (e.g., claimant, administrator, reviewer).
  • Status: The user's account status (e.g., active, inactive).

3. Claim Lifecycle & Statuses

The Claim Lifecycle describes the entire journey of a claim, from its initial submission to its final resolution. This journey is primarily driven by changes in the Claim Status.

• Common Claim Statuses:
  • Submitted: The initial status of a claim after a user submits it.
  • Pending: Claims awaiting review or further action.
  • Processed: Claims that have undergone initial automated or manual review.
  • Approved: Claims that have been validated and accepted for payment.
  • Rejected: Claims that have been denied.

When a claim's status changes, the system typically triggers Notifications to inform relevant parties.

4. Automated Claim Processing

The system includes Automated Claim Processing via scheduled tasks. These tasks run periodically (e.g., hourly) to automatically evaluate and update claims based on predefined criteria. For example, claims with a Pending status might be automatically moved to Processed after a certain period or condition.

5. User Authentication & Authorization

• Authentication: The process of verifying a user's identity. Users provide credentials (like username and password) to log in. The system uses secure password encoding and OAuth2 for robust authentication.
• Authorization: Once authenticated, Authorization determines what actions a user is permitted to perform based on their assigned Role. For instance, only authenticated users can access most system functionalities, while login and register endpoints are publicly accessible. The system leverages JWT (JSON Web Tokens) for secure session management.

6. Notifications

Notifications are real-time or near real-time alerts and messages sent to users to inform them about significant events, most notably Claim Status Updates. The system uses Apache Kafka as a distributed streaming platform to handle these messages asynchronously, ensuring reliable and decoupled communication.

• Types of Notifications:
  • Claim Status Update: Informs a user when their claim's status has changed (e.g., from Submitted to Processed).
  • User Notifications: General messages or system alerts sent to specific users.
  • Email Notifications: The system sends emails (e.g., for claim status updates) by consuming messages from Kafka topics.

7. Reporting

The system offers Reporting capabilities to generate summaries and detailed reports about claims. These reports provide valuable insights into claim processing volumes, status distributions, and aggregated financial data.

• Key Reports:
  • Claim Report by Status: A breakdown of claims by their current status, often including totals and amounts.
  • Claims Summary: An overview of all claims, providing metrics like the total number of claims and the total amount claimed.

8. Claim Status Cache (Redis)

The system uses Redis as an in-memory data store to cache frequently accessed data, specifically Claim Statuses. This Claim Status Cache allows for extremely fast retrieval of a claim's current status, improving the overall responsiveness and performance of the application by reducing direct database lookups.
