Designing a Dorm Social Connection Platform: Technical Architecture and Database Schema

To facilitate college students in befriending each other in dorms, we'll design a mobile-first application with a microservices architecture, utilizing a graph database for social connections and a relational database for user profiles and events. The system will prioritize privacy, scalability, and real-time interactions.

Introduction

The challenge at hand is to create a technical solution that fosters social connections among college students living in dorms. This involves designing a system that can handle user profiles, social interactions, and event management while ensuring privacy, scalability, and engaging user experience. I'll outline a comprehensive technical approach, focusing on the architecture and database schema that can support these requirements.

Step 1

Clarify the Technical Requirements (3-4 minutes)

Before diving into the solution, I'd like to clarify a few key technical aspects:

• Looking at the potential scale of this system, I'm considering a microservices architecture to handle different functionalities independently. Could you provide insights into the expected user base size and growth rate? This will help determine if a microservices approach is justified or if a monolithic structure would suffice initially.

Why it matters: Determines the initial architecture and scalability needs. Expected answer: 10,000 initial users with 50% year-over-year growth. Impact on approach: Would lean towards microservices for future scalability.

• Considering the sensitive nature of student data, I'm thinking about implementing end-to-end encryption for user communications. Are there any specific data protection regulations or university policies we need to adhere to?

Why it matters: Influences the security measures and data handling processes. Expected answer: FERPA compliance required, along with university-specific data policies. Impact on approach: Would necessitate robust encryption and access control mechanisms.

• Given the dynamic nature of dorm life, I'm considering real-time features like instant messaging and live event updates. What's our stance on using WebSocket technology for these real-time interactions?

Why it matters: Affects the choice of backend technologies and infrastructure requirements. Expected answer: Open to WebSocket technology if it enhances user experience without compromising performance. Impact on approach: Would incorporate WebSocket servers into the architecture for real-time features.

• Thinking about the social graph aspect, I'm leaning towards using a graph database for managing connections. Are there any preferences or constraints regarding database technologies we should be aware of?

Why it matters: Influences the database schema design and query performance for social features. Expected answer: No specific constraints, open to using the most suitable technology for the use case. Impact on approach: Would proceed with a hybrid database approach, using a graph database for social connections and a relational database for structured data.
