The purpose of the ORDER BY clause in a SQL SELECT statement is to sort the results returned by the query. This clause can sort the results in ascending (ASC) or descending (DESC) order based on one or more columns.

Here's a step-by-step explanation:

1. The SELECT statement is used to select data from a database. The data returned is stored in a result table, called the result-set.

2. The ORDER BY keyword is added at the end of the SELECT statement, followed by the column(s) you want to sort the result-set by.

3. By default, the ORDER BY clause sorts the data in ascending order. If you want to sort the data in descending order, you can use the DESC keyword.

For example, if you have a table named "Students" with columns "Name" and "Age", and you want to sort the result-set by "Age" in descending order, you would write the query like this:

SELECT * FROM Students
ORDER BY Age DESC;

This will return a result-set with the oldest students listed first.
