Select the incorrect statement(s).Row is called a ‘Tuple’.Table is called a ‘Attribute’.Column header is called an ‘Attribute’.Table is called a ‘Tuple’.
Solution 1
The incorrect statements are:
- "Row is called a ‘Tuple’." - This is incorrect because in the context of databases, a row is often referred to as a 'record'.
- "Table is called a ‘Attribute’." - This is incorrect because a table is not called an 'Attribute'. An attribute usually refers to a column in a table.
- "Table is called a ‘Tuple’." - This is incorrect because a table is not called a 'Tuple'. A tuple usually refers to a row in a table.
Solution 2
The incorrect statements are:
-
"Row is called a ‘Tuple’." - This is incorrect because a row in a table is not called a 'Tuple'. In the context of databases, a tuple usually refers to a single, often immutable, ordered list of elements.
-
"Table is called a ‘Attribute’." - This is incorrect because a table is not called an 'Attribute'. An attribute in the context of databases usually refers to a column in a table.
-
"Table is called a ‘Tuple’." - This is incorrect because a table is not called a 'Tuple'. As mentioned above, a tuple usually refers to a single, ordered list of elements.
The only correct statement is "Column header is called an ‘Attribute’." because in the context of databases, an attribute refers to a column in a table.
Solution 3
The incorrect statements are:
-
"Row is called a ‘Tuple’." - This is incorrect because a row in a table is not called a 'Tuple'. In the context of databases, a tuple usually refers to a single, complete set of data in a table. So, it's more accurate to say that a row contains a tuple, not that a row is a tuple.
-
"Table is called a ‘Attribute’." - This is incorrect because a table is not called an 'Attribute'. An attribute usually refers to a column in a table.
-
"Table is called a ‘Tuple’." - This is incorrect because a table is not called a 'Tuple'. As mentioned above, a tuple usually refers to a single, complete set of data in a table, not the table itself.

- "Row is called a ‘Tuple’." - This is incorrect because in the context of databases, a row is often referred to as a 'record'.
