What type of data values are required to have the same data types?

The correct answer is that data values in the same field are required to have the same data types. In databases, a field refers to a single column within a table, and it is designed to store a specific type of information, such as text, numbers, or dates. Each field has a defined data type that dictates the kind of data it can hold.

For instance, if a field is set to store integer values, every entry in that field must be an integer; it cannot contain text or decimal numbers. This uniformity ensures consistency and integrity in the data stored within that field, enabling effective data management and processing.

In contrast, data values in the same record can belong to different fields, each potentially having its own data type. Data values in the same table are also not restricted to the same data type, as tables can contain multiple fields of varying types. Likewise, data values in different fields don't need to match in data type; they are intended to store different types of information. Thus, it is only the individual fields that require uniform data types for their entries.
