Sure, here's a step-by-step guide on how to create these tables:

1. **CUSTOMERS Table:**

This table will store all the customer related data. Here's a basic structure:

```sql
CREATE TABLE CUSTOMERS (
ID INT PRIMARY KEY,
NAME VARCHAR(100),
EMAIL VARCHAR(100),
PHONE_NUMBER VARCHAR(15)
);
```

This creates a table named CUSTOMERS with four columns: ID, NAME, EMAIL, and PHONE_NUMBER. The ID is the primary key, which means it uniquely identifies each record in the table.

2. **BOOKINGS Table:**

This table will store all the booking related data. Here's a basic structure:

```sql
CREATE TABLE BOOKINGS (
ID INT PRIMARY KEY,
CUSTOMER_ID INT,
BOOKING_DATE DATE,
DESTINATION VARCHAR(100),
FOREIGN KEY (CUSTOMER_ID) REFERENCES CUSTOMERS(ID)
);
```

This creates a table named BOOKINGS with four columns: ID, CUSTOMER_ID, BOOKING_DATE, and DESTINATION. The ID is the primary key. The CUSTOMER_ID is a foreign key that references the ID in the CUSTOMERS table. This establishes a link between the two tables.

3. **PAYMENTS Table:**

This table will store all the payment related data. Here's a basic structure:

```sql
CREATE TABLE PAYMENTS (
ID INT PRIMARY KEY,
BOOKING_ID INT,
PAYMENT_DATE DATE,
AMOUNT DECIMAL(10,2),
FOREIGN KEY (BOOKING_ID) REFERENCES BOOKINGS(ID)
);
```

This creates a table named PAYMENTS with four columns: ID, BOOKING_ID, PAYMENT_DATE, and AMOUNT. The ID is the primary key. The BOOKING_ID is a foreign key that references the ID in the BOOKINGS table. This establishes a link between the two tables.

Please note that this is a basic structure. You might need to add more columns based on your specific requirements. Also, you might need to add more constraints to ensure the data integrity.
