В этом видео мы рассмотрим как можно создать правильную БД архитектуру, при этом мы не будем акцентировать внимание на конкретной БД. Вы можете выбрать любую популярную БД: PostgreSQL, MSSQL, MySQL, Oracle итд В этом курсе видео мы рассмотрим как создавать приложение с нуля, как настроить правильные процессы, как работать с задачами, как создать приложение, как поддерживать высокое качество продукта. Постараемся затронуть как можно больше технологий, расскажу крутые фишки, которые использую на практике.
