iBATIS

( Duration: 1 Day )

The iBATIS training course is designed to expose developers to the open source framework while also exploring real-world memory, performance and other issues that are associated to any persistence framework. After taking this course, you should be able to persist the data in Java objects faster and build applications that are more flexible and easier to maintain.

By attending iBATIS workshop, delegates will learn to:

  • Gain an understanding of iBATIS as a data mapper and how it differs from other persistent frameworks like Hibernate and JPA in Java
  • Retrieve relational data into Java objects using the iBATIS framework
  • Explore methods of inserting, updating, and removing data from the database using iBATIS and Java objects
  • See how to relate objects and automatically have iBATIS retrieve data for associated objects
  • Explore performance and memory issues associated with object relationships
  • See how to utilize lazy loading in iBATIS to reduce the number of objects in memory
  • Understand how to solve the N+1 selects issue in iBATIS
  • Study how iBATIS handles class inheritance
  • Understand the four different levels or scopes of transactions that iBATIS supports
  • See and use iBATIS Dynamic SQL tags for generating SQL at runtime

  • A solid understanding of Java is required
  • An understanding of relational databases, SQL and JDBC is helpful

This iBATIS class is suitable for Java programmers who have interest in learning how to persist Java object data using the iBATIS open source data mapper.
