In databases, a function is defined as?

Explanation:
A function in databases is a block of code that takes input values, performs a calculation or transformation on data, and returns a result that you can use in queries. This lets you encapsulate computations so you can reuse them across statements, for example calculating a discounted price, formatting a string, or converting data types within a SELECT or WHERE clause. It’s about producing a value from data, not about looping, managing memory, or displaying web content.
