Software Architecture Document for Customer Web Interface
by

This document outlines the architecture for a Customer Web Interface, detailing system components, user flows, database structures, and integrations to support efficient shipment and account management.

1. Introduction

1.1 Purpose

The Customer Web Interface is designed to provide users with a platform for managing shipments, orders, billing, and accounts. This interface will allow users to create and track shipments, manage their address book, view invoices, top up balances, and perform various account-related tasks. It also supports API integrations, notifications, and enhanced security measures.

1.2 Scope

This document outlines the architecture and technical framework required to develop and deploy the Customer Web Interface, including system components, user flows, data structures, and the technologies required to implement the solution.

2. System Overview

2.1 Users

The interface will cater to two primary user types:

  • Business Users: Those managing bulk shipments.
  • Individual Users: Customers handling personal shipments.

Each user type will have access to specific features based on their account type and requirements.

2.2 System Modules

Key modules include:

  • Dashboard
  • Shipments
  • Address Book
  • Billing
  • API Integrations
  • Notifications
  • Security

This diagram will depict the overall system architecture, showing the interaction between the frontend, backend, database, and external services.

3.2 Components

3.2.1 Frontend

  • Technology Stack: HTML, CSS, JavaScript (React.js framework suggested for dynamic content).
  • Key Features:
    • Dynamic content rendering based on user actions.
    • Integration with Google Maps and What3Words for location services.
    • Responsive design for optimal usability across different devices.

3.2.2 Backend

  • Technology Stack: Node.js or Python for the API layer.
  • Key Features:
    • Handles business logic for creating orders, user profile management, and payment processing.
    • Integrates with third-party services for payment processing and shipment tracking.
    • Ensures secure access to data and API integrations.

3.2.3 Database

  • Database Type: MySQL/PostgreSQL for relational data; Redis for caching.
  • Key Features:
    • Stores user profiles, shipment details, billing information, and API keys securely.
    • Ensures data integrity and efficient access control, with encryption for sensitive data.

3.2.4 APIs

  • Key Features:
    • Allows API key generation and deletion.
    • Facilitates interactions with external tracking, payment, and notification services.

3.2.5 Notifications

  • Channels: Email, WhatsApp.
  • Key Features: Configurable alerts to keep users informed of shipment statuses and account-related actions.

3.2.6 Security

  • Authentication: JWT or OAuth for secure user sessions.
  • Encryption: Bcrypt for passwords, SSL/TLS for secure data transfer.

4. Detailed Design

4.1 Functional Components

4.1.1 User Account Management

  • Processes:
    • Registration, login, and password reset flows.
    • CRUD operations for user accounts and profile information.

4.1.2 Order and Shipment Management

  • Processes:
    • Creation of new shipments with parcel details, pickup and delivery locations, and service levels.
    • Special requests such as after-hours delivery, tender delivery, and more.

4.1.3 Billing & Top-Up

  • Processes:
    • Account balance top-up through payment gateway integrations.
    • Management of transaction history and invoices.

4.1.4 Notifications

  • Processes:
    • Configurable notifications for shipment updates and account balances, with options for email and WhatsApp channels.

4.1.5 API Integrations

  • Processes:
    • Create, edit, and delete API keys for external integrations.
    • API functions for real-time tracking, billing, and shipment updates.

4.2 Non-Functional Requirements

4.2.1 Performance

  • Target response times of less than 2 seconds for primary actions.
  • Caching mechanisms to enhance speed for frequently accessed data.

4.2.2 Scalability

  • The system must support horizontal scaling, especially for peak usage periods.
  • Utilization of a microservices approach to support separate scaling of modules like the shipment and billing services.

4.2.3 Security

  • Encryption for sensitive user data and API communications.
  • Secure token management for user sessions and multi-factor authentication where applicable.

6. Deployment Architecture

6.1 Environment Setup

  • Development: Local and cloud-based for initial development.
  • Staging: Pre-production environment to test features.
  • Production: Hosted on a cloud platform for deployment.

6.2 Servers

  • Frontend: Served via a CDN for optimal performance and low latency.
  • Backend: Hosted on scalable cloud services like AWS Lambda or EC2.
  • Database: Cloud-hosted databases such as AWS RDS or Google Cloud SQL.
