(IBATIS is an open source project of Apache. It is an ORM solution. The greatest feature of iBATIS is that it is small and easy to use. Using the ORM mechanism provided by iBATIS, business logic implementers face pure Java goals. This layer is basically the same as implementing ORM through Hibernate. For detailed data operations, Hibernate will automatically generate SQL sentences, while iBATIS requires developers to write detailed SQL sentences. Compared with Hibernate and other "fully automatic" ORM mechanisms, iBATIS provides more free space for system design with the concession of SQL development workload and database portability. As a beneficial supplement to the "fully automatic" ORM implementation, iBATIS appears to have a special meaning.
