Question

a) Record
b) Entity
c) Table
d) Attribute
e) Tuple

Answer 1

In databases, a 'Record', 'Tuple', and sometimes 'Entity' can all refer to a row in a database table, while 'Attribute' refers to a column and 'Table' refers to the collection of rows and columns.

Step-by-step explanation:

In the context of a database table, a row is typically referred to by several terms. The options that also refer to a row in a database table are:

• Record: This is a common term used to describe a row in a table, which holds individual instances of data.
• Tuple: In relational database theory, a tuple is a term often used to refer to a row.
• Entity: This term is more abstract, but in the context of databases, an entity can refer to a unique instance of data, which usually corresponds to a row in a table.

An attribute, on the other hand, generally refers to a column in a table, which is a specific field that holds a piece of information about all the records. Lastly, a table refers to the entire collection of rows and columns.
