+## Database Schema Setup
+
+### 1. Main Database (vbot_main)
+
+1. **Create Database**
+   ```sql
+   CREATE DATABASE vbot_main;
+   USE vbot_main;
+   ```
+
+2. **Create Customers Table**
+   ```sql
+   CREATE TABLE customers (
+       id INT AUTO_INCREMENT PRIMARY KEY,
+       name VARCHAR(100) NOT NULL,
+       company_name VARCHAR(100) NOT NULL,
+       email VARCHAR(100) UNIQUE NOT NULL,
+       api_key VARCHAR(64) UNIQUE NOT NULL,
+       is_active BOOLEAN DEFAULT TRUE,
+       created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+       updated_at DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+       -- Database credentials for customer's own database
+       db_host VARCHAR(255),
+       db_port INT,
+       db_name VARCHAR(100),
+       db_user VARCHAR(100),
+       db_password VARCHAR(255)
+   );
+   ```
+
+3. **Create Indexes**
+   ```sql
+   CREATE INDEX idx_api_key ON customers(api_key);
+   CREATE INDEX idx_email ON customers(email);
+   CREATE INDEX idx_is_active ON customers(is_active);
+   ```
+
+### 2. Customer Database
+
+1. **Create Database**
+   ```sql
+   CREATE DATABASE customer_db_name;
+   USE customer_db_name;
+   ```
+
+2. **Create Call Records Table**
+   ```sql
+   CREATE TABLE call_records (
+       id VARCHAR(36) PRIMARY KEY,
+       customer_id INT NOT NULL,
+       caller_number VARCHAR(20) NOT NULL,
+       called_number VARCHAR(20) NOT NULL,
+       file_path VARCHAR(255),
+       transcription TEXT,
+       summary TEXT,
+       sentiment VARCHAR(20),
+       keywords TEXT,
+       created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+       updated_at DATETIME DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+       FOREIGN KEY (customer_id) REFERENCES customers(id)
+   );
+   ```
+
+3. **Create Indexes**
+   ```sql
+   CREATE INDEX idx_customer_id ON call_records(customer_id);
+   CREATE INDEX idx_created_at ON call_records(created_at);
+   CREATE INDEX idx_caller_number ON call_records(caller_number);
+   CREATE INDEX idx_called_number ON call_records(called_number);
+   ```
+
+### 3. Database User Setup
+
+1. **Main Database User**
+   ```sql
+   -- Create user for main database
+   CREATE USER 'vbot_admin'@'%' IDENTIFIED BY 'your_secure_password';
+   GRANT ALL PRIVILEGES ON vbot_main.* TO 'vbot_admin'@'%';
+   FLUSH PRIVILEGES;
+   ```
+
+2. **Customer Database User**
+   ```sql
+   -- Create user for customer database
+   CREATE USER 'customer_user'@'%' IDENTIFIED BY 'customer_secure_password';
+   GRANT ALL PRIVILEGES ON customer_db_name.* TO 'customer_user'@'%';
+   FLUSH PRIVILEGES;
+   ```
+
+### 4. Database Connection Testing
+
+1. **Test Main Database Connection**
+   ```bash
+   # Test connection
+   mysql -h your-main-db-host -u vbot_admin -p vbot_main
+   
+   # Test queries
+   USE vbot_main;
+   SELECT * FROM customers;
+   ```
+
+2. **Test Customer Database Connection**
+   ```bash
+   # Test connection
+   mysql -h customer-db-host -u customer_user -p customer_db_name
+   
+   # Test queries
+   USE customer_db_name;
+   SELECT * FROM call_records;
+   ```
+
+### 5. Database Backup Setup
+
+1. **Main Database Backup**
+   ```bash
+   # Create backup script
+   cat > backup_main.sh << 'EOF'
+   #!/bin/bash
+   BACKUP_DIR="/path/to/backups"
+   DATE=$(date +%Y%m%d_%H%M%S)
+   
+   # Create backup
+   mysqldump -h your-main-db-host -u vbot_admin -p vbot_main > \
+       "$BACKUP_DIR/vbot_main_$DATE.sql"
+   
+   # Compress backup
+   gzip "$BACKUP_DIR/vbot_main_$DATE.sql"
+   
+   # Keep only last 7 days of backups
+   find $BACKUP_DIR -name "vbot_main_*.sql.gz" -mtime +7 -delete
+   EOF
+   
+   # Make script executable
+   chmod +x backup_main.sh
+   ```
+
+2. **Customer Database Backup**
+   ```bash
+   # Create backup script
+   cat > backup_customer.sh << 'EOF'
+   #!/bin/bash
+   BACKUP_DIR="/path/to/backups"
+   DATE=$(date +%Y%m%d_%H%M%S)
+   
+   # Create backup
+   mysqldump -h customer-db-host -u customer_user -p customer_db_name > \
+       "$BACKUP_DIR/customer_db_$DATE.sql"
+   
+   # Compress backup
+   gzip "$BACKUP_DIR/customer_db_$DATE.sql"
+   
+   # Keep only last 7 days of backups
+   find $BACKUP_DIR -name "customer_db_*.sql.gz" -mtime +7 -delete
+   EOF
+   
+   # Make script executable
+   chmod +x backup_customer.sh
+   ```
+
+### 6. Database Monitoring
+
+1. **Set Up Monitoring Queries**
+   ```sql
+   -- Check database size
+   SELECT table_schema AS "Database",
+   ROUND(SUM(data_length + index_length) / 1024 / 1024, 2) AS "Size (MB)"
+   FROM information_schema.tables
+   GROUP BY table_schema;
+   
+   -- Check table sizes
+   SELECT table_name AS "Table",
+   ROUND(((data_length + index_length) / 1024 / 1024), 2) AS "Size (MB)"
+   FROM information_schema.tables
+   WHERE table_schema = "customer_db_name"
+   ORDER BY (data_length + index_length) DESC;
+   
+   -- Check record counts
+   SELECT COUNT(*) FROM call_records;
+   ```
+
+2. **Set Up Alerts**
+   ```bash
+   # Create monitoring script
+   cat > monitor_db.sh << 'EOF'
+   #!/bin/bash
+   
+   # Check database size
+   DB_SIZE=$(mysql -h customer-db-host -u customer_user -p -N -e "
+       SELECT ROUND(SUM(data_length + index_length) / 1024 / 1024, 2)
+       FROM information_schema.tables
+       WHERE table_schema = 'customer_db_name'
+   ")
+   
+   # Alert if size exceeds 1GB
+   if (( $(echo "$DB_SIZE > 1024" | bc -l) )); then
+       echo "Database size exceeds 1GB: $DB_SIZE MB"
+       # Add your alert mechanism here (email, Slack, etc.)
+   fi
+   EOF
+   
+   # Make script executable
+   chmod +x monitor_db.sh
+   ```
