System Architecture

Designing an ERP system is a complex task, and it requires careful consideration of various technical aspects. Below is a detailed description of the system architecture for your PHP-based ERP system with a MySQL database. 

• Three-Tier Architecture:
  Presentation Layer: User interfaces developed using HTML, CSS, and JavaScript.
  Application Layer: PHP-based business logic handling user requests and interactions.
  Data Layer: MySQL database for storing and retrieving data.
• Server Configuration:
  Web Server: High End Linux server or a cloud server like AWS shall be used to deploy the application.
  Database Server: MySQL database will be used as a database server on the Linux server or Cloud server.
•  Frameworks and Libraries:
  PHP Framework: PHP framework like CodeIgniter, Laravel or Symfony for rapid development and maintainability.
  Frontend Libraries: Utilize libraries like jQuery or Vue.js for enhanced frontend functionality.
• Containerization:
  Docker: Containerize the application for easy deployment and scalability using Dockers.
• Version Control:
  
  Git: Implement version control to track changes in the source code and collaborate with the development team.
• Continuous Integration/Continuous Deployment (CI/CD):
  
  CI/CD Pipeline: Set up a CI/CD pipeline to automate testing, building, and deploying the application.
•  Monitoring and Logging:
  Monitoring: Employ server side monitoring to uptime management and uninterrupted usage.
  Logging: Implement logging mechanisms to capture errors and system events for analysis.
• Cloud Integration:
  
  Cloud Services: Consider integrating with cloud services for scalability and flexibility.
  Data Storage: Utilize cloud-based storage solutions for backups and data redundancy.
• Localization:
  Localization: Allow users to customize date formats, currencies, and other regional settings.
• Testing & Integration:
  
  Unit Testing: Implement unit tests to ensure individual components function correctly.
  Integration Testing: Perform testing to validate the interactions between different modules.
