But what if we want to get the highest observation? As you remember, sorting in SQL is realized in ascending order, so the biggest values are on the bottom.

In SQL you can easily sort in reverse (descending) order. To do it use `DESC` keyword followed or preceded by column name. You can also put column names within the parenthesis of `DESC` keyword. So, there are two variants of using `DESC`:
- `DESC(col_name)`;
- `col_name DESC`;

For example, we can order cars by mileage, but this time in descending order.

SELECT *
FROM audi_cars
ORDER BY mileage DESC

> Please note, that there is also `ASC` keyword in SQL used for ascending sorting. Since default sorting in SQL is in ascending order, this keyword is rarely used.

SQL is a domain-specific programming language widely used by data scientists, analysts, etc for manipulating and extracting necessary data. Nowadays, SQL is a must-have point in the CV for every potential analyst, data scientist. In this course, you will be introduced to the very basics of SQL.

In this section, you will be introduced to the very basics of SQL: extracting one or multiple columns from a database.

In this section, you will learn how to filter observations so only necessary rows will be extracted.

In this section, you will learn about the usage of different aggregating functions for your table, such as minimum, maximum, average... 

In this section, you will learn how to sort your table, even having filters and aggregate functions applied to a table.

In this section, you will learn about grouping observations and usage of this principle.

This chapter is designed for users who have completed the previous sections and want to consolidate knowledge.
