Mybatis was originally an open source project ibatis of Apache. In 2010, the project was migrated from Apache Software Foundation to Google Code and renamed mybatis. Moved to GitHub in November 2013. Ibatis comes from the combination of "Internet" and "abatis". It is a persistence layer framework based on Java.

Mybatis is an excellent persistence layer framework that supports common SQL queries, stored procedures and advanced mapping. Mybatis eliminates almost all the manual setting of JDBC code and parameters and the retrieval encapsulation of result sets. Mybatis can use simple XML or annotations for configuration and original mapping, and map the interface and Java POJO (plain old Java objects) into records in the database.
