Ultra-Light JDBC Persistance Layer

Yank is a very easy-to-use yet flexible SQL-centric persistence layer for JDBC-compatible databases build on top of org.apache.DBUtils. Yank is a different approach to the over-ORMing of Java persistence. Rather than try to abstract away the SQL underneath, Yank assumes you want low level control over the SQL queries you execute. Yank wraps DBUtils, hiding the nitty-gritty Connection and ResultSet handling behind a straight-forward proxy class: Yank. “Query” methods execute SELECT statements and return POJOs or a List of POJOs. “Execute” methods execute INSERT, UPDATE, and DELETE (and other) statements. Recently, annotation-based column-field mapping, batch executing, column list querying and scalar querying has been added. Since version 3.0.0, Yank uses the Hikari connection pool as its integrated connection pool.

Usage is very simple: Simply define jobs, define triggers, and start the yank scheduler.
