Point of Sales System Recipe

Description

A comprehensive recipe for building a point of sales system using SynapCores database.

Prerequisites

• Database setup with RocksDB storage
• Familiarity with SQL syntax and data types
• Basic understanding of business logic and requirements

Steps

Step 1: Create Employee Table

CREATE TABLE employees (
    employee_id INT PRIMARY KEY,
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    email VARCHAR(100) UNIQUE NOT NULL,
    role VARCHAR(20) NOT NULL CHECK (role IN ('Manager', 'Salesperson'))
);

Step 2: Create Products Table

CREATE TABLE products (
    product_id INT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    description TEXT,
    price DECIMAL(10, 2) NOT NULL,
    category VARCHAR(20) NOT NULL CHECK (category IN ('Electronics', 'Clothing', 'Home Goods'))
);

Step 3: Create Orders Table

CREATE TABLE orders (
    order_id INT PRIMARY KEY,
    customer_name VARCHAR(100) NOT NULL,
    order_date DATE NOT NULL,
    total DECIMAL(10, 2) NOT NULL
);

Step 4: Create Orders Items Table

CREATE TABLE orders_items (
    order_item_id INT PRIMARY KEY,
    order_id INT NOT NULL REFERENCES orders(order_id),
    product_id INT NOT NULL REFERENCES products(product_id),
    quantity INT NOT NULL CHECK (quantity > 0)
);

Step 5: Create Store Information Table

CREATE TABLE store_info (
    store_id INT PRIMARY KEY,
    address VARCHAR(200) NOT NULL,
    city VARCHAR(50) NOT NULL,
    state VARCHAR(20) NOT NULL,
    zip_code VARCHAR(10) NOT NULL
);

Step 6: Create Inventory Table

CREATE TABLE inventory (
    product_id INT PRIMARY KEY REFERENCES products(product_id),
    quantity INT NOT NULL CHECK (quantity > 0)
);

Step 7: Create Purchase Orders Table

CREATE TABLE purchase_orders (
    purchase_order_id INT PRIMARY KEY,
    order_date DATE NOT NULL,
    total DECIMAL(10, 2) NOT NULL
);

Step 8: Insert Initial Data

INSERT INTO employees (employee_id, first_name, last_name, email, role)
VALUES (1, 'John', 'Doe', 'john.doe@example.com', 'Manager');

INSERT INTO products (product_id, name, description, price, category)
VALUES (1, 'Product A', 'Description of Product A', 10.99, 'Electronics'),
       (2, 'Product B', 'Description of Product B', 9.99, 'Clothing');

INSERT INTO orders (order_id, customer_name, order_date, total)
VALUES (1, 'Jane Doe', '2023-02-15', 20.00);

INSERT INTO orders_items (order_item_id, order_id, product_id, quantity)
VALUES (1, 1, 1, 2),
       (2, 1, 2, 1);

Step 9: Update Inventory

UPDATE inventory
SET quantity = 10
WHERE product_id = 1;

UPDATE inventory
SET quantity = 5
WHERE product_id = 2;

Step 10: Generate Purchase Orders

INSERT INTO purchase_orders (purchase_order_id, order_date, total)
VALUES (1, '2023-02-20', 30.00);

Verification

SELECT * FROM employees;
SELECT * FROM products;
SELECT * FROM orders;
SELECT * FROM orders_items;
SELECT * FROM store_info;
SELECT * FROM inventory;
SELECT * FROM purchase_orders;

-- Verify that the initial data has been inserted correctly

-- Check that the product quantities have been updated correctly
SELECT quantity FROM inventory WHERE product_id = 1;
SELECT quantity FROM inventory WHERE product_id = 2;

Notes

• Make sure to update the role column in the employees table according to your business requirements.
• You may need to adjust the data types and constraints based on your specific use case.
• This recipe assumes that you have already set up a RocksDB storage engine for SynapCores.
