While there are excellent commercial tools available, I found a gap in the open-source market for something that was both simple and highly functional without excessive overhead. At the time, I was working extensively with Java and JDBC . Given that JDBC drivers exist for virtually every data source, I decided to architect my own utility: JDBMig .
