Final Answer:
Sure, here are the data types you might consider for each of those columns:
- a. Weight of a person: DECIMAL (5, 2) or FLOAT, depending on the precision needed.
- b. Day of marriage: DATE
- c. Water usage of a city in gallons: DECIMAL or FLOAT, depending on the precision needed.
- d. Title of a person: VARCHAR or CHAR, depending on the maximum length allowed.
- e. X-ray of a person: BLOB or VARBINARY, depending on the storage needs for the X-ray image.
Step-by-step explanation:
For the weight of a person, the ideal data type could be DECIMAL(5,2) or FLOAT. DECIMAL allows for precise storage of numeric values, with the numbers before and after the decimal point specified (5 digits total, with 2 after the decimal point, for instance). FLOAT is used for approximate numeric values like weight, where precision might not be critical.
The day of marriage would best be stored as a DATE data type. This format allows for easy manipulation and comparison of dates, ensuring consistency and simplicity in handling date-related operations.
Regarding water usage of a city in gallons, a DECIMAL or FLOAT data type would suitably accommodate this information. DECIMAL would provide fixed-point precision, while FLOAT would allow for scientific notation and accommodate a wide range of values.
The title of a person, such as 'Mr.,' 'Ms.,' or 'Dr.,' could be stored as a VARCHAR or CHAR data type, depending on the maximum length of the titles.
For an X-ray image of a person, a BLOB (Binary Large Object) or VARBINARY data type is typically used to store binary data like images. These data types can accommodate the large amounts of information within an X-ray image.
The complete question:
Specify the data type (e.g. DECIMAL (6,2)) you would use for the
following columns:
- a. Weight of a person
- b. Day of marriage
- c. Water usage of a city in gallons
- d. Title of a person
- e. X-ray of a person
