🎯 Dubai DLD Analytics API - Ready to Deploy

✅ Implementation Complete

Your Dubai Land Department Analytics API is fully implemented with:

🧠 Context-Aware Query Processing

• Multi-turn conversations: Users can refine queries progressively
• Session management: 30-minute context retention
• Natural refinements: "Summarise by week", "Apartments only"
• Context merging: Follow-up queries inherit previous context

📊 All 10 Questions Implemented

1. ✅ Q1-3: Rental price trend with context awareness
2. ✅ Q4: Brief about the Project (transaction summary)
3. ✅ Q5: List of fast moving projects in last 6 months
4. ✅ Q6: Which area is seeing uptick in off-plan projects
5. ✅ Q7: Which area is having more rental transactions
6. ✅ Q8: Top 5 areas for Commercial leasing and why
7. ✅ Q9: Top 5 areas for Residential leasing and why
8. ✅ Q10: Avg price of 3BHK apartment by area (monthly, top 5)

🎨 Chart.js Integration

• Line Charts: Time series trends
• Bar Charts: Area comparisons
• Pie Charts: Distributions
• Cards: Summary statistics

Specific Query Endpoints

GET /api/queries/project-summary-detail      # Q4
GET /api/queries/fast-moving-projects       # Q5
GET /api/queries/offplan-uptick            # Q6
GET /api/queries/top-areas                 # Q7
GET /api/queries/commercial-leasing        # Q8

🎯 Context Flow Example

// Q1: Initial query
POST /api/query
{
  "query": "Give me the last 6 months rental price trend for Business Bay",
  "sessionId": "user123"
}
// Returns: Monthly rental data for Business Bay

// Q2: Refinement - Change grouping
POST /api/query
{
  "query": "Summarise by week",
  "sessionId": "user123"
}
// Returns: SAME data (Business Bay, last 6 months) but WEEKLY grouped

// Q3: Refinement - Add filter
POST /api/query
{
  "query": "Apartments only",
  "sessionId": "user123"
}
// Returns: SAME data with WEEKLY grouping, FILTERED to apartments
