In a DBMS Lab, `consultation_fee` is a database attribute used to store the amount charged by a doctor or healthcare professional for a consultation. It is generally defined using the `DECIMAL` data type because a consultation fee is a monetary value that may contain decimal fractions. For example, a doctor may charge ₹500.00, ₹750.50, or ₹1,200.75. Using `DECIMAL` ensures that the value is stored accurately without the rounding problems that can occur with floating-point data types. A suitable definition can be written as: ```sql consultation_fee DECIMAL(10,2) ``` Here, `10` represents the total number of digits that can be stored, while `2` represents the number of digits allowed after the decimal point. Therefore, `DECIMAL(10,2)` can store values such as `500.00`, `1250.50`,
