The iBATIS Data Mapper framework will help you to significantly reduce the amount of Java code that you
normally need to access a relational database. iBATIS simply maps JavaBeans to SQL statements using a
very simple XML descriptor. Simplicity is the key advantage of iBATIS over other frameworks and object
relational mapping tools. To use the iBATIS Data Mapper you need only be familiar with JavaBeans, XML
and SQL. There is very little else to learn. There is no complex scheme required to join tables or execute
complex queries. Using Data Mapper you have the full power of real SQL at your fingertips.
