the Hibernate Query Language HQL or Enterprise JavaBeans Query Language EJBQL. MYBATIS Design Features MyBatis comes with the following design philosophies − Simplicity − MyBatis is widely regarded all of the features of SQL. Supports dynamic SQL − MyBatis provides features for dynamic building SQL queries based on parameters. Supports O/RM − MyBatis supports many of the same features as an O/RM
