# 🎯 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

## 🚀 Quick Start (3 Steps)

npm install
```

### Step 3: Start Server
```bash
npm run dev
```

## 🧪 Test Everything
```bash
./test_api.sh
```

## 📱 Interactive Dashboard

## 📡 API Endpoints

### Context-Aware Queries
```bash
# Q1: Initial query
POST /api/query
{
  "query": "Give me the last 6 months rental price trend for Business Bay",
  "sessionId": "user123"
}

# Q2: Refine to weekly
POST /api/query
{
  "query": "Summarise by week",
  "sessionId": "user123"
}

# Q3: Filter apartments
POST /api/query
{
  "query": "Apartments only",
  "sessionId": "user123"
}
```

### Specific Query Endpoints
```bash
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
GET /api/queries/residential-leasing       # Q9
GET /api/queries/bhk-apartment-price       # Q10
```

## 🎯 Context Flow Example

```javascript
// 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
```
