There are plenty of persistence frameworks in the
Java community. iBATIS is an open source "data mapper" framework. Data mappers do not tie classes to tables or class fields to columns. Instead, a data mapper maps parameters and results of
SQL statements to classes and fields. This makes iBATIS a simple and lightweight persistence framework. By removing the repetitive and error prone work, iBATIS helps remove developers from focusing on low level
JDBC code. In fact, the iBATIS documentation states the goal of iBATIS is to a provide 80% of JDBC functionality using only 20% of the code.a
This hands on course will expose developers to this open source framework while also teaching awareness of some real-world memory, performance and other issues that are associated to any persistence framework. After taking this class, your developers should be able to persist the data in Java objects faster and build applications that are more flexible and easier to maintain.
