Design Rationale

The design decisions for this urban planning dashboard prioritize flexibility, performance, and user experience. React was chosen for its component-based architecture, allowing for modular and reusable UI elements essential for a customizable dashboard. Node.js on the backend provides a JavaScript-based full-stack solution, simplifying development and maintenance.

PostgreSQL was selected for its robust handling of geographic data and complex queries, which are crucial for urban planning applications. The inclusion of Redis addresses the need for real-time data handling and caching to ensure responsive performance even with large datasets.

The file structure separates concerns clearly, promoting maintainability and scalability. The implementation plan follows an iterative approach, allowing for early testing and feedback on core features. The deployment strategy emphasizes reliability and security, crucial for an application handling sensitive urban planning data.

Overall, these choices aim to create a powerful, user-friendly tool that can adapt to the diverse needs of urban planners while maintaining high performance and data integrity.
