About this course

Этот курс посвящён всестороннему изучению SQL и работе с базами данных на примере MySQL. Материал построен от основ к сложным темам и рассчитан на практическое освоение языка: от установки сервера и настройки окружения до проектирования базы, написания запросов и работы с транзакциями. Мы начнём с установки MySQL и работы в терминале, познакомимся с графическими IDE (Workbench, DBeaver) и базовыми способами взаимодействия с сервером.

Затем разберём структуру базы: первичные и внешние ключи, индексы, типы данных, правила именования объектов, таблицы-справочники и ER-диаграммы. Освоим команды DDL и DML, научимся добавлять, обновлять и удалять данные, фильтровать и сортировать записи, использовать агрегирующие функции, группировку, подзапросы и соединения. Дальше курс охватывает расширенные возможности SQL: оконные и рекурсивные табличные выражения, представления, хранимые процедуры, пользовательские функции, триггеры, переменные и работу с транзакциями, блокировки и уровни изоляции.

Особое внимание уделено анализу запросов (EXPLAIN), оптимизации и предотвращению SQL-инъекций. Кому будет полезен курс:новичкам, желающим изучить SQL с нуля;студентам для практики проектирования и написания запросов;ИТ-специалистам для систематизации знаний и расширения опыта работы с MySQL. Чему вы научитесь:проектировать базы данных и работать с таблицами;писать различные SQL-запросы и оптимизировать их выполнение;использовать процедуры, функции, триггеры и переменные;работать с транзакциями, блокировками и анализировать выполнение запросов;безопасно взаимодействовать с базой данных, предотвращая ошибки и SQL-инъекции.

Курс полностью практический, с примерами, заданиями и контрольными вопросами. Добро пожаловать на курс и успехов в изучении SQL!
