What is a criterion of a table being in first normal form?All transitive functional dependencies of a non-prime attribute of a super key should be removed.No non-prime attributes dependent on the candidate key should be included.Every cell of a table should have a single value.For every functional dependency where X is functionally dependent on Y, X should be the super key of the table.
Question
What is a criterion of a table being in first normal form?All transitive functional dependencies of a non-prime attribute of a super key should be removed.No non-prime attributes dependent on the candidate key should be included.Every cell of a table should have a single value.For every functional dependency where X is functionally dependent on Y, X should be the super key of the table.
Solution
The question seems to be asking for the criteria of a table being in first normal form (1NF) in database normalization. Here are the steps to determine if a table is in 1NF:
-
Atomic Values: Every cell of a table should have a single value. This means that there should be no sets, arrays, or lists in any single cell. Each cell should contain only atomic, indivisible values.
-
Primary Key: Each table should have a primary key. This is a unique identifier for each record in the table.
-
Order Does Not Matter: The order in which data is recorded does not matter. This means that the rows can be swapped without changing the meaning or use of the table.
The other criteria mentioned in the question are related to higher forms of normalization (2NF, 3NF, etc.) and are not required for a table to be in first normal form.
