Why take this course?

🚀 Курс JDBC: ConnectionPool, Transaction, DAO

🎓 **Инструкторы: Dzianis Matveyenka_

🎉 Вот что ждет вас на курсе:

Основы курса:

  • **Предпосылка знаний: Комфортно осведомые про Java Core, владеем основными принципами SQL и знакомы с хотя бы одной реляционной базой данных.
  • **Язык обучения: Java и JDBC._
  • **База данных: PostgreSQL._
  • **Инструмент разработки: IntelliJ IDEA._

Ключевые моменты курса:

Работа с базами данных:

  • Изучение механизмов отправки DDL и DML запросов из Java приложений.

JDBC API:

  • Различия между классами Statement и PreparedStatement и их эффективное использование.
  • Понимание роли и настройки JDBC драйвера в Java приложении без Maven/Gradle.

Конфигурация соединения:

  • Работа с properties файлом для управления настройками подключения к базе данных.

Транзакции и ACID:

  • Понимание транзакций, их роли и уровней изоляции.
  • Изучение принципов ACID и его важности в работе с базами данных.

Оптимизация запросов:

  • Настройка параметров запросов, таких как fetch size, batch size и timeout.

Connection Pool:

  • Практическое применение и значение использования Connection Pool в Java.

DAO (Data Access Object):

  • Понимание и реализация шаблона проектирования DAO для улучшения и модулизации доступа к данным.

📚 **Почему это важно:

  • Важность Connection Pool: Особенно в приложениях с высокой нагрузкой, он предотвращает избыточное создание и закрытие соединений с базой данных, что уменьшает нагрузку на сервер и повышает производительность.
  • DAO в реальном мире: Шаблон DAO используется во многих современных Java-приложениях, чтобы обеспечить абстракцию слоя доступа к данным, что делает код более читаемым и легким для поддержки.

  • Clear and Effective Instruction: The instructor delivers the content in a clear, articulate manner, speaking distinctly without any noticeable speech impediments or errors. This makes for a pleasant listening experience.

  • Structured Content: The course is well-structured, starting from basic concepts and gradually moving towards more complex topics. There are no abrupt jumps in difficulty, which facilitates easier comprehension and learning.

  • Comprehensive Coverage: The course covers the basics of SQL, not just focusing on JDBC API as it is also covered in a separate course by the author. This ensures that learners have a solid foundation before diving into more advanced topics.

  • Actionable Learning Path: The course provides clear guidance on what to study and how to progress, with knowledge presented in a structured and interconnected manner.

  • Best Practices: The author demonstrates best practices and uses real code examples while explaining the nuances, which is particularly valuable for those who have some prior knowledge of JDBC but lacked a comprehensive understanding.

  • Detail-Oriented Approach: Particularly in Section 3, the course delves into how ORM frameworks operate under the hood, offering a valuable learning experience.

  • Recommended for Beginners and Intermediate Learners: The course is ideal for beginners and those with intermediate knowledge who wish to deepen their understanding of JDBC and database connectivity in Java applications.

Areas for Improvement:

  • More Detailed Explanations: Some reviewers suggested that certain aspects were explained too briefly and could have benefited from more detailed explanations.

  • Supplementary Materials: A few reviewers recommended supplementing the course with additional resources, such as a book or an overview, to enhance the learning experience and make the initial study phase more effective.

Overall Verdict:

This course is highly recommended for anyone looking to understand JDBC and database connectivity in Java applications. The positive reviews and high global rating are a testament to its effectiveness in conveying complex concepts in a clear and structured manner. Whether you're new to the topic or looking to solidify your existing knowledge, this course offers valuable insights and practical examples that will help you become a proficient backend developer.
