Tutorial - Property Search & Review System
Introduction
Building on the foundation established in our Housing Rental Platform tutorial, we now focus on creating sophisticated search and review functionality. This tutorial demonstrates how to implement the features that transform a basic property database into a comprehensive rental marketplace where users can discover, evaluate, and book accommodations.
We'll work with real Airbnb data from Hong Kong to create practical, production-ready features that handle the complexity of modern rental platforms.
User Journey & Core Scenarios
Let's explore the typical user journey on a rental platform, from initial search to post-stay review:
1. Property Discovery
Users start by searching for properties using various criteria:
- Keyword Search: Location names, property types, or specific features
- Date-based Availability: Checking calendar availability for specific dates
- Location Proximity: Finding properties near points of interest
2. Filtering & Refinement
Once users have initial results, they refine their search with filters:
- Quality Filters: Minimum rating requirements
- Capacity Needs: Number of beds, bathrooms, or guest capacity
- Budget Constraints: Price range filtering
- Amenity Requirements: Specific features like WiFi, parking, or pools
3. Property Evaluation
Before booking, users research properties by:
- Reading Guest Reviews: Learning from previous experiences
- Analyzing Ratings: Understanding overall satisfaction levels
- Checking Recent Feedback: Ensuring current quality standards
4. Post-Stay Engagement
After their stay, users contribute to the platform by:
- Writing Reviews: Sharing their experience with future guests
- Rating Properties: Providing numerical feedback on various aspects
- Updating Reviews: Modifying feedback if circumstances change
Database Schema Design
Our platform requires three core tables to support the complete user journey:
Property Listings Table
The listings
table serves as our central repository for property information:
Guest Reviews Table
The reviews
table captures user feedback and experiences:
Availability Calendar Table
The calendar
table tracks property availability and pricing by date:
Data Import & Setup
Let's set up our database with sample data. First, verify your tables are created:
Now import the sample data using the COPY command:
Enable Full-Text Search
To support keyword-based property searches, we'll add a full-text search column:
Feature Implementation
