Final answer:
For the weight of a person, a DECIMAL(6,2) data type is suitable, allowing for weights up to 9999.99 with a precision of two decimal places.
Step-by-step explanation:
To specify the data type for the column representing the weight of a person, one should consider the precision and scale required to accurately record such a measurement. In general, a person's weight is a quantitative continuous data type that is measured with a certain degree of precision. A suitable data type for this could be DECIMAL or FLOAT. For most applications, a DECIMAL data type with a precision and scale such as DECIMAL(6,2) would be sufficient. This allows for weights up to 9999.99 kilograms or pounds, accommodating a very comprehensive range of possible weights with a precision up to two decimal places, which is typically enough for recording the weight of a person.
For example, if a weight is recorded in kilograms and we wish to accommodate weights up to 9999.99 kg, the DECIMAL(6,2) format allows us to store numbers from 0.00 to 9999.99, accommodating the majority of real use cases for tracking human weight.
