Question

........is eliminating duplication of tuples.

Answer 1

The process of eliminating duplication of tuples in a database or dataset is referred to as **removing duplicates** or **deduplication**. In the context of relational databases, this is often accomplished through operations in SQL, such as using the `SELECT DISTINCT` statement, which retrieves unique records from a table. Additionally, one might use methods like `GROUP BY` to group records based on certain attributes and ensure that only unique tuples are retained in the result set.
