You are an entrepreneur and starting a new e-business ✓ Solved

You are an entrepreneur and starting a new e-business (100% electronic/online business - no physical location). 1. Write a paragraph describing your business in details 2. Create the conceptual data model like we learned in chapter 5 3. Create the Database Design like we learned in chapter 6 4. Use SQL Server to construct the Database like we learned in chapter 7 including the relevant queries. Make sure to insert no less than 10 rows in every table.

Paper For Above Instructions

In today's digital age, entrepreneurs have the unique opportunity to build fully online businesses that cater to consumers worldwide. My e-business, "EcoGadgets," specializes in selling environmentally friendly electronic products. The business aims to provide a curated selection of gadgets such as solar-powered chargers, biodegradable phone cases, and energy-efficient smart home devices. Our mission is to promote sustainable living while offering high-quality, innovative electronics. With partnerships with eco-conscious manufacturers, EcoGadgets will not only sell products but also educate consumers about the importance of reducing electronic waste. Our website will feature user-friendly navigation, detailed product descriptions, customer reviews, and an engaging blog focused on sustainable tech trends. Additionally, we plan to incorporate a loyalty program to reward customers for their purchases and referrals. By leveraging social media marketing and search engine optimization, EcoGadgets will reach a wide audience passionate about eco-friendliness and technology.

Conceptual Data Model

To support our e-business operations, we will develop a conceptual data model that outlines the essential entities and their relationships. The main entities in our model include Customers, Products, Orders, Payments, and Reviews. Each entity will have distinct attributes:

  • Customers: CustomerID (PK), FirstName, LastName, Email, Phone, Address

  • Products: ProductID (PK), ProductName, Description, Price, StockQuantity

  • Orders: OrderID (PK), OrderDate, CustomerID (FK), TotalAmount

  • Payments: PaymentID (PK), OrderID (FK), PaymentDate, Amount, PaymentMethod

  • Reviews: ReviewID (PK), ProductID (FK), CustomerID (FK), Rating, Comment

The relationships can be defined as follows:

  • One customer can place multiple orders (1:N).

  • Each order can have one payment (1:1).

  • One product can have multiple reviews (1:N).

  • One customer can leave multiple reviews (1:N).

Database Design

Based on the conceptual model, the database design for EcoGadgets includes the following tables:

  1. Customers: 

    CREATE TABLE Customers (
    

    CustomerID INT PRIMARY KEY,
    

    FirstName VARCHAR(50),
    

    LastName VARCHAR(50),
    

    Email VARCHAR(100) UNIQUE,
    

    Phone VARCHAR(15),
    

    Address VARCHAR(255)
    

    );

  2. Products: 

    CREATE TABLE Products (
    

    ProductID INT PRIMARY KEY,
    

    ProductName VARCHAR(100),
    

    Description TEXT,
    

    Price DECIMAL(10, 2),
    

    StockQuantity INT
    

    );

  3. Orders: 

    CREATE TABLE Orders (
    

    OrderID INT PRIMARY KEY,
    

    OrderDate DATETIME,
    

    CustomerID INT,
    

    TotalAmount DECIMAL(10, 2),
    

    FOREIGN KEY (CustomerID) REFERENCES Customers(CustomerID)
    

    );

  4. Payments: 

    CREATE TABLE Payments (
    

    PaymentID INT PRIMARY KEY,
    

    OrderID INT,
    

    PaymentDate DATETIME,
    

    Amount DECIMAL(10, 2),
    

    PaymentMethod VARCHAR(50),
    

    FOREIGN KEY (OrderID) REFERENCES Orders(OrderID)
    

    );

  5. Reviews: 

    CREATE TABLE Reviews (
    

    ReviewID INT PRIMARY KEY,
    

    ProductID INT,
    

    CustomerID INT,
    

    Rating INT CHECK (Rating >= 1 AND Rating <= 5),
    

    Comment TEXT,
    

    FOREIGN KEY (ProductID) REFERENCES Products(ProductID),
    

    FOREIGN KEY (CustomerID) REFERENCES Customers(CustomerID)
    

    );

Populating the Database

We will insert a minimum of 10 rows in each table to ensure adequate testing and functionality before launching our e-business. Here is an example of how to insert data into the Customers and Products tables:

INSERT INTO Customers (CustomerID, FirstName, LastName, Email, Phone, Address) VALUES 


(1, 'John', 'Doe', 'john.doe@example.com', '1234567890', '123 Main St'),


(2, 'Jane', 'Smith', 'jane.smith@example.com', '0987654321', '456 Elm St'),


(3, 'Emily', 'Johnson', 'emily.johnson@example.com', '5551234567', '789 Oak St'),


(4, 'Michael', 'Williams', 'michael.williams@example.com', '3216549870', '321 Pine St'),


(5, 'Linda', 'Brown', 'linda.brown@example.com', '6543219870', '159 Cedar St'),


(6, 'James', 'Jones', 'james.jones@example.com', '1472583690', '753 Maple St'),


(7, 'Robert', 'Garcia', 'robert.garcia@example.com', '1597538462', '258 Birch St'),


(8, 'Jennifer', 'Martinez', 'jennifer.martinez@example.com', '9632587410', '369 Walnut St'),


(9, 'David', 'Davis', 'david.davis@example.com', '6549873210', '741 Spruce St'),


(10, 'Mary', 'Rodriguez', 'mary.rodriguez@example.com', '2854679130', '258 Chestnut St');

INSERT INTO Products (ProductID, ProductName, Description, Price, StockQuantity) VALUES 


(1, 'Solar Charger', 'A portable solar charger for devices.', 29.99, 100),


(2, 'Biodegradable Phone Case', 'An eco-friendly phone case.', 19.99, 200),


(3, 'Energy-efficient Smart Home Device', 'Smart device to reduce energy consumption.', 49.99, 150),


(4, 'LED Light Bulbs', 'Long-lasting LED bulbs.', 14.99, 300),


(5, 'Recycled Laptop Sleeve', 'Protect your laptop with a recycled sleeve.', 24.99, 80),


(6, 'Eco-Friendly Mouse', 'A sustainable computer mouse.', 29.99, 60),


(7, 'Solar-Powered Garden Lights', 'Light up your garden sustainably.', 39.99, 40),


(8, 'Smart Thermostat', 'Manage your home temperature efficiently.', 99.99, 35),


(9, 'Energy Monitor', 'Monitor your energy usage.', 39.99, 25),


(10, 'Compostable Charging Cable', 'A charging cable that composts.', 15.99, 150);

Additional records will be added for the Orders, Payments, and Reviews tables as needed, adhering to the same structure.

Conclusion

Through EcoGadgets, we aim to harness technology to foster an environmentally friendly lifestyle. By implementing the database design and populating it with real data, we will ensure a robust platform ready for consumer interaction. As we advance, we will continuously monitor and optimize our offerings based on customer feedback and sales trends.
