In access create a database Accumulation. In stores, regular customers are usually offered to buy a store card. By presenting this card

during the payment of the product, virtual money is calculated, the size of which depends on the purchase amount

and which the buyer can use to pay for new purchases. Create a structure for a new relational database named Accumulation, intended for the accounting of virtual money. The database must contain information

about the buyer's name, card number, date of purchase and the amount of virtual money earned.

The database must meet the following conditions:

$$ the database structure is created in such a way that data duplication is not allowed;

$$ each table field contains an indivisible unit of information;

$$ appropriate data types are selected for all fields;

$$ all tables contain a primary key field;

$$ a relation $($relation$)$ is established between the tables, ensuring referential integrity.

$$ NO need to enter data into the database!
