Answer 1

Field names in an expression are enclosed in quotation marks, which is a convention in programming and database languages to reference specific columns or data elements.

Step-by-step explanation:

When we are required to refer to a field name in an expression, the field name is always enclosed in quotation marks. This convention is typically used in many programming languages and database query languages like SQL. For example, if you were selecting a column named "Username" from a database, you might write a query like SELECT "Username" FROM users; Additionally, languages like JSON format data objects using quotation marks around field names, such as {"Username": "exampleUser"}.

Answer 2

When referencing a field name in an expression, the field name is always enclosed in brackets.

Step-by-step explanation:

When referencing a field name in an expression, it is crucial to enclose the field name in brackets. This syntax is commonly used in programming and database queries to specify a particular variable or attribute. Brackets help distinguish the field name from other elements in the expression and ensure accurate data retrieval or manipulation.

Unlike parentheses used for grouping or mathematical operations, brackets serve the specific purpose of signaling a field or variable in contexts such as coding languages, SQL queries, or spreadsheet formulas, enhancing clarity and precision in data-related operations.
