for the past 10 years, a restaurant has been running a customer loyalty program, rewarding customers with discounts and treats. records of these rewards have been kept in odd notes and multiple spreadsheets used in different ways by various employees who have come and gone over the years. because of this, some customers are not getting their rewards, while others are receiving rewards they have not earned. overall, the restaurant is losing money and business with this program. how can a database management system (dbms) help with this problem?
