+# Database Migration Issues - SOLVED
+
+## Problem Summary
+You were experiencing unwanted tables being created and duplicates when starting the server. This was caused by multiple migration sources creating the same tables and conflicting migration execution.
+
+## Root Causes Identified
+
+### 1. **Multiple Migration Sources**
+- PostgreSQL init script (`databases/scripts/init.sql`) creates the `dev_pipeline` database
+- Shared schemas (`databases/scripts/schemas.sql`) creates core tables
+- Individual service migrations create their own tables
+- Template-manager was also applying shared schemas, causing duplicates
+
+### 2. **Migration Execution Order Issues**
+- Services were running migrations in parallel
+- No proper dependency management between shared schemas and service-specific tables
+- DROP TABLE statements in development mode causing data loss
+
+### 3. **Table Conflicts**
+- `users` table created by both `schemas.sql` and `user-auth` migration
+- `user_projects` table created by both sources
+- Function conflicts (`update_updated_at_column()` created multiple times)
+- Extension conflicts (`uuid-ossp` created multiple times)
+
+## Solutions Implemented
+
+### 1. **Fixed Migration Order**
+- Created separate `shared-schemas` service for core database tables
+- Updated migration script to run in correct order:
+  1. `shared-schemas` (core tables first)
+  2. `user-auth` (user-specific tables)
+  3. `template-manager` (template-specific tables)
+
+### 2. **Made Migrations Production-Safe**
+- Replaced `DROP TABLE IF EXISTS` with `CREATE TABLE IF NOT EXISTS`
+- Prevents data loss on server restarts
+- Safe for production environments
+
+### 3. **Eliminated Duplicate Table Creation**
+- Removed shared schema application from template-manager
+- Each service now only creates its own tables
+- Proper dependency management
+
+### 4. **Created Database Cleanup Script**
+- `scripts/cleanup-database.sh` removes unwanted/duplicate tables
+- Can be run to clean up existing database issues
+
+## How to Use
+
+### Clean Up Existing Database
+```bash
+cd /home/tech4biz/Desktop/Projectsnew/CODENUK1/codenuk-backend-live
+./scripts/cleanup-database.sh
+```
+
+### Start Server with Fixed Migrations
+```bash
+docker-compose up --build
+```
+
+The migrations will now run in the correct order:
+1. Shared schemas (projects, tech_stack_decisions, etc.)
+2. User authentication tables
+3. Template management tables
+
+## Files Modified
+
+1. **`services/template-manager/src/migrations/migrate.js`**
+   - Removed shared schema application
+   - Now only handles template-specific tables
+
+2. **`services/user-auth/src/migrations/001_user_auth_schema.sql`**
+   - Replaced DROP TABLE with CREATE TABLE IF NOT EXISTS
+   - Made migration production-safe
+
+3. **`services/template-manager/src/migrations/001_initial_schema.sql`**
+   - Replaced DROP TABLE with CREATE TABLE IF NOT EXISTS
+   - Made migration production-safe
+
+4. **`scripts/migrate-all.sh`**
+   - Added shared-schemas service
+   - Proper migration order
+
+5. **`docker-compose.yml`**
+   - Removed APPLY_SCHEMAS_SQL environment variable
+
+6. **Created new files:**
+   - `services/shared-schemas/` - Dedicated service for shared schemas
+   - `scripts/cleanup-database.sh` - Database cleanup script
+
+## Expected Results
+
+After these changes:
+- ✅ No duplicate tables will be created
+- ✅ No unwanted tables from pgAdmin
+- ✅ Proper migration order
+- ✅ Production-safe migrations
+- ✅ Clean database schema
+
+## Verification
+
+To verify the fix worked:
+1. Run the cleanup script
+2. Start the server
+3. Check pgAdmin - you should only see the intended tables
+4. No duplicate or unwanted tables should appear

+# Tech Stack Selector -- Postgres + Neo4j Knowledge Graph
+
+This project provides a **price-focused technology stack selector**.\
+It uses a **Postgres relational database** for storing technologies and
+pricing, and builds a **Neo4j knowledge graph** to support advanced
+queries like:
+
+> *"Show me all backend, frontend, and cloud technologies that fit a
+> \$10-\$50 budget."*
+
+------------------------------------------------------------------------
+
+## 📌 1. Database Schema (Postgres)
+
+The schema is designed to ensure **data integrity** and
+**price-tier-driven recommendations**.
+
+### Core Tables
+
+-   **`price_tiers`** -- Foundation table for price categories (tiers
+    like *Free*, *Low*, *Medium*, *Enterprise*).
+-   **Category-Specific Tables** -- Each technology domain has its own
+    table:
+    -   `frontend_technologies`
+    -   `backend_technologies`
+    -   `cloud_technologies`
+    -   `database_technologies`
+    -   `testing_technologies`
+    -   `mobile_technologies`
+    -   `devops_technologies`
+    -   `ai_ml_technologies`
+-   **`tools`** -- Central table for business/productivity tools with:
+    -   `name`, `category`, `description`
+    -   `primary_use_cases`
+    -   `popularity_score`
+    -   Pricing fields: `monthly_cost_usd`, `setup_cost_usd`,
+        `license_cost_usd`, `training_cost_usd`,
+        `total_cost_of_ownership_score`
+    -   Foreign key to `price_tiers`
+
+All category tables reference `price_tiers(id)` ensuring **referential
+integrity**.
+
+------------------------------------------------------------------------
+
+## 🧱 2. Migration Files
+
+Your migrations are structured as follows:
+
+1.  **`001_schema.sql`** -- Creates all tables, constraints, indexes.
+2.  **`002_tools_migration.sql`** -- Adds `tools` table and full-text
+    search indexes.
+3.  **`003_tools_pricing_migration.sql`** -- Adds cost-related fields to
+    `tools` and links to `price_tiers`.
+
+Run them in order:
+
+``` bash
+psql -U <user> -d <database> -f sql/001_schema.sql
+psql -U <user> -d <database> -f sql/002_tools_migration.sql
+psql -U <user> -d <database> -f sql/003_tools_pricing_migration.sql
+```
+
+------------------------------------------------------------------------
+
+## 🕸️ 3. Neo4j Knowledge Graph Design
+
+We map relational data into a graph for semantic querying.
+
+### Node Types
+
+-   **Technology** → `{name, category, description, popularity_score}`
+-   **Category** → `{name}`
+-   **PriceTier** → `{tier_name, min_price, max_price}`
+
+### Relationships
+
+-   `(Technology)-[:BELONGS_TO]->(Category)`
+-   `(Technology)-[:HAS_PRICE_TIER]->(PriceTier)`
+
+Example graph:
+
+    (:Technology {name:"NodeJS"})-[:BELONGS_TO]->(:Category {name:"Backend"})
+    (:Technology {name:"NodeJS"})-[:HAS_PRICE_TIER]->(:PriceTier {tier_name:"Medium"})
+
+------------------------------------------------------------------------
+
+## 🔄 4. ETL (Extract → Transform → Load)
+
+Use a Python ETL script to pull from Postgres and load into Neo4j.
+
+### Example Script
+
+``` python
+from neo4j import GraphDatabase
+import psycopg2
+
+pg_conn = psycopg2.connect(host="localhost", database="techstack", user="user", password="pass")
+pg_cur = pg_conn.cursor()
+
+driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "password"))
+
+def insert_data(tx, tech_name, category, price_tier):
+    tx.run("""
+    MERGE (c:Category {name: $category})
+    MERGE (t:Technology {name: $tech})
+    ON CREATE SET t.category = $category
+    MERGE (p:PriceTier {tier_name: $price_tier})
+    MERGE (t)-[:BELONGS_TO]->(c)
+    MERGE (t)-[:HAS_PRICE_TIER]->(p)
+    """, tech=tech_name, category=category, price_tier=price_tier)
+
+pg_cur.execute("SELECT name, category, tier_name FROM tools JOIN price_tiers ON price_tiers.id = tools.price_tier_id")
+rows = pg_cur.fetchall()
+
+with driver.session() as session:
+    for name, category, tier in rows:
+        session.write_transaction(insert_data, name, category, tier)
+
+pg_conn.close()
+driver.close()
+```
+
+------------------------------------------------------------------------
+
+## 🔍 5. Querying the Knowledge Graph
+
+### Find technologies in a price range:
+
+``` cypher
+MATCH (t:Technology)-[:HAS_PRICE_TIER]->(p:PriceTier)
+WHERE p.min_price >= 10 AND p.max_price <= 50
+RETURN t.name, p.tier_name
+ORDER BY p.min_price ASC
+```
+
+### Find technologies for a specific domain:
+
+``` cypher
+MATCH (t:Technology)-[:BELONGS_TO]->(c:Category)
+WHERE c.name = "Backend"
+RETURN t.name, t.popularity_score
+ORDER BY t.popularity_score DESC
+```
+

+
+## 📋 Detailed Workflow Steps
+
+### 1. **Request Reception & Validation**
+```
+Client Request → Unison Service → Middleware Stack
+```
+
+**Components:**
+- **Express Server** (Port 8014)
+- **Security Middleware** (Helmet, CORS)
+- **Rate Limiting** (100 req/15min per IP)
+- **Request Validation** (Joi schema validation)
+- **Body Parsing** (JSON, URL-encoded)
+
+**Validation Rules:**
+- Domain: 1-100 characters
+- Budget: Positive number
+- Preferred Technologies: Array of strings (1-50 chars each)
+- Template ID: Valid UUID format
+- Boolean flags: includeSimilar, includeKeywords, forceRefresh
+
+### 2. **Route Processing**
+```
+POST /api/recommendations/unified → Unified Recommendation Handler
+GET /api/recommendations/tech-stack → Tech Stack Only Handler
+GET /api/recommendations/template/:id → Template Only Handler
+GET /health → Health Check Handler
+```
+
+### 3. **Unified Recommendation Workflow** (Main Flow)
+
+#### 3.1 **Input Validation**
+```javascript
+// Validate tech stack request parameters
+const techStackRequest = { domain, budget, preferredTechnologies };
+const techStackValidation = schemaValidator.validateTechStackRequest(techStackRequest);
+
+// Validate template request if templateId provided
+if (templateId) {
+  const templateRequest = { templateId, includeSimilar, includeKeywords, forceRefresh };
+  const templateValidation = schemaValidator.validateTemplateRequest(templateRequest);
+}
+```
+
+#### 3.2 **Parallel Service Calls**
+```javascript
+// Always fetch from tech-stack-selector
+const techStackPromise = techStackService.getRecommendations({
+  domain, budget, preferredTechnologies
+}).catch(error => ({ success: false, error: error.message, source: 'tech-stack-selector' }));
+
+// Fetch from template-manager if templateId provided
+const templatePromise = templateId ? 
+  templateService.getAIRecommendations(templateId, { forceRefresh })
+    .catch(error => ({ success: false, error: error.message, source: 'template-manager' })) :
+  Promise.resolve({ success: false, error: 'No template ID provided', source: 'template-manager' });
+
+// Execute both calls in parallel
+const [techStackResult, templateResult] = await Promise.all([techStackPromise, templatePromise]);
+```
+
+#### 3.3 **Service Integration Details**
+
+**Tech Stack Selector Integration:**
+- **Endpoint**: `POST /recommend/best`
+- **Data Source**: PostgreSQL + Neo4j (migrated data)
+- **Features**: Price-based relationships, Claude AI recommendations
+- **Response**: Array of tech stack recommendations with costs, team sizes, etc.
+
+**Template Manager Integration:**
+- **Endpoint**: `GET /api/templates/{id}/ai-recommendations`
+- **Data Source**: Template database with AI analysis
+- **Features**: Template-based recommendations, feature learning
+- **Response**: Template-specific tech stack recommendations
+
+#### 3.4 **Decision Logic & Fallback Strategy**
+
+```javascript
+// Check if we have at least one successful recommendation
+if (!techStackResult.success && !templateResult.success) {
+  return res.status(500).json({
+    success: false,
+    error: 'Failed to fetch recommendations from both services'
+  });
+}
+
+// If only one service succeeded, return its result
+if (!techStackResult.success || !templateResult.success) {
+  const successfulResult = techStackResult.success ? techStackResult : templateResult;
+  return res.json({
+    success: true,
+    data: successfulResult.data,
+    source: successfulResult.source,
+    message: 'Single service recommendation (other service unavailable)'
+  });
+}
+```
+
+#### 3.5 **Claude AI Unification** (When Both Services Succeed)
+
+**Claude AI Integration:**
+- **Model**: claude-3-sonnet-20240229
+- **Max Tokens**: 4000
+- **Timeout**: 30 seconds
+- **API**: Anthropic Claude API
+
+**Prompt Engineering:**
+```javascript
+const prompt = `You are an expert tech stack architect. I need you to analyze two different tech stack recommendations and create a single, optimized recommendation that balances cost, domain requirements, and template-feature compatibility.
+
+## Original Request Parameters:
+- Domain: ${requestParams.domain}
+- Budget: $${requestParams.budget}
+- Preferred Technologies: ${requestParams.preferredTechnologies?.join(', ')}
+- Template ID: ${requestParams.templateId}
+
+## Tech Stack Selector Recommendation:
+${JSON.stringify(techStackRecommendation.data, null, 2)}
+
+## Template Manager Recommendation:
+${JSON.stringify(templateRecommendation.data, null, 2)}
+
+## Your Task:
+Analyze both recommendations and create a single, optimized tech stack recommendation that:
+1. Balances cost-effectiveness with the budget constraint
+2. Matches the domain requirements
+3. Incorporates the best features from the template recommendation
+4. Considers the preferred technologies when possible
+5. Provides realistic team size, development time, and success metrics
+
+## Required Output Format:
+[Detailed JSON schema requirements...]`;
+```
+
+**Response Processing:**
+```javascript
+// Parse Claude's response
+const claudeResponse = response.data.content[0].text;

+  "recommendation_score": number (0-100, overall recommendation score),
+  "message": "string (brief explanation of the recommendation, max 500 characters)"

+## Important Notes:
+- The JSON must be valid and complete
+- All numeric values should be realistic
+- The recommendation should be practical and implementable
+- Consider the budget constraints carefully
+- Balance between cost and quality
+- Include reasoning in the message field
