Thank you for taking a look at the JCL module. My hope is that you will find it a low cost and powerful solution for performing data Extract, Transform, and Load (ETL) tasks. JCL leverages the power of Perl to allow you to do almost anything you want with data when extracting from, or load to database tables.
JCL was developed to handle the maintenance of a medium sized HR Data Mart. Data for this Data Mart comes from Oracle, SQLServer, and Teradata databases. It took over two years to develop JCL. It is now stable and in daily production use. Permission was granted by my company to release JCL to the public domain in January of 2009.
If you would like more information about how JCL is being used, please feel free to contact me. I can be reached using the name bradjadkins at the domain mac dot com.
