II. Services Architecture

2A. Services Configuration

Advanced Services Schemasql

CREATE TABLE services (
    id INT AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(255) NOT NULL,
    category ENUM('interior', 'exterior', 'maintenance') NOT NULL,
    base_price DECIMAL(10,2) NOT NULL,
    pricing_config JSON NOT NULL DEFAULT '{}',
    business_rules JSON NOT NULL DEFAULT '{}'
);

2B. Sub-Services Matrix

Add-on Architecturesql

CREATE TABLE sub_services (
    id INT AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(255) NOT NULL,
    price DECIMAL(10,2) NOT NULL,
    is_active BOOLEAN DEFAULT TRUE
);

III. Booking Orchestration

3A. Managed State Records

Advanced Bookings Schemasql

CREATE TABLE bookings (
    id INT AUTO_INCREMENT PRIMARY KEY,
    booking_number VARCHAR(20) NOT NULL UNIQUE,
    customer_id INT NULL,
    booking_date DATE NOT NULL,
    start_time TIME NOT NULL,
    end_time TIME NOT NULL,
    status ENUM('pending', 'confirmed', 'completed', 'cancelled')
);

3B. Conflict Prevention

Validation Proceduresql

CREATE PROCEDURE validate_booking(IN p_date DATE, IN p_staff INT)
BEGIN
    IF EXISTS (SELECT 1 FROM bookings WHERE staff_id = p_staff AND booking_date = p_date) THEN
        SIGNAL SQLSTATE '45000' SET MESSAGE_TEXT = 'Slot already reserved';
    END IF;
END;

IV. Temporal Architecture

4A. Dynamic Slotting

Time Slot Configurationsql

CREATE TABLE slot_config (
    day_of_week TINYINT,
    start_time TIME,
    end_time TIME,
    buffer_minutes INT DEFAULT 15,
    max_concurrent_slots INT DEFAULT 1
);

4B. Availability Management

Availability Functionsql

CREATE FUNCTION get_available_slots(p_date DATE) RETURNS JSON
READS SQL DATA
BEGIN
    -- Real-time slot computation logic
    RETURN '[]';
END;

V. Performance & Optimization

5A. JSON Indexing

Optimization Schemasql

-- Indexing nested JSON keys for speed
ALTER TABLE services ADD INDEX idx_json_min_price ((
    CAST(JSON_UNQUOTE(JSON_EXTRACT(pricing_config, '$.min_price')) AS DECIMAL(10,2))
));

VI. Operational Continuity

Common Issues

Race Conditions

Enforce strict transaction isolation.

JSON Parsing Lag

Use generated columns for hot keys.
