An example of a database is a customer relationship management (CRM) system used by a business. The CRM system would have a database that stores information about the business's customers, such as contact information, purchase history, and any notes about interactions with the customer. The business could use the CRM system to manage customer interactions, track sales, and analyze customer behavior.
Another example would be an e-commerce website that uses a database to store information about the products for sale, including descriptions, prices, and images. The website's database would also store information about customer orders, including items ordered, shipping addresses, and payment information.
