🚀 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
иPreparedStatement
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
иtimeout
.
✅ 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.
