Question

What statement is correct regarding fields?

a)It is a useful design to have multiple values in a field and parse it to get the one you need
b)If you need to parse a field in tables to get the data then they are badly designed
c)It is better to have a field made up of multiple values.
d)Every field must be made up a single value

Answer 1

The correct statement is that every field must be made up of a single value, as having multiple values in a field or a field made up of multiple values can lead to data inconsistency and other issues.

Step-by-step explanation:

The correct statement regarding fields is d) Every field must be made up a single value. Fields in a database table represent individual pieces of data, and it is important to keep each field limited to a single value to maintain data integrity and make it easier to process and retrieve information.

Having multiple values in a field and then parsing it to get the one you need, as mentioned in option a), is not a recommended design practice. It can lead to data inconsistency, difficulty in querying the database, and increased complexity in application logic.

While option c) suggests having a field made up of multiple values, this approach violates the principles of database normalization and can result in data redundancy, update anomalies, and decreased performance.

Therefore, the most correct statement is that every field must be made up of a single value, as mentioned in option d).
