Which of the following data fields would not be classified as a string (text) data type?

Question

In examining which data field would not be classified as a string (text) data type, we must consider typical data type classifications for common data fields.
Option 1: ID Number. While it may appear numeric, ID numbers are often stored as strings to preserve leading zeros, special formats, or hyphenation. Therefore, it is commonly treated as text in many databases, even though digits are involved.
Option 2: Last Name. This is clearly textual data, consisting of alphabetic characters, and is almost always stored as a string in databases and data processing systems.
Option 3: Transaction Date. This represents a date value, which is conceptually a date/time data type rather than plain text. Dates support operations like comparisons, formatting, and date arithmetic, which strings cannot perform reliably.
Option 4: Industry Code. An industry code can be numeric or alphanumeric depending on the coding scheme used (for example, codes like 123 or codes like A12). Even when numeric in appearance, it is typically stored as a string to preserve leading zeros or fixed-width formatting, similar to an ID number. However, since the prompt asks which would not be a string, the standout non-text option is the one that explicitly represents a date.
If we weigh the possibilities, the data field that inherently represents a temporal value rather than text is the Transaction Date, making it the non-string data type among the options. Other fields are typically treated as strings because they represent identifiers, names, or coded values that benefit from preserving exact character sequences.
Note: Depending on data governance rules, some systems might store all fields as strings for simplicity, but the conventional, type-aware approach distinguishes dates from text.
