The MyBatis SQL mapper framework makes it easier to use a relational database with object-oriented
applications. MyBatis couples objects with stored procedures or SQL statements using a XML descriptor or
annotations. Simplicity is the biggest advantage of the MyBatis data mapper over object relational mapping
tools.
