Spring Batch follows the traditional batch architecture where a job repository does the work of scheduling and interacting with the job. A job can have more than one step. And every step typically follows the sequence of reading data, processing it and writing it. And of course the framework will do most of the heavy lifting for us here — especially when it comes to the low-level persistence work of dealing with the jobs — using h2 for the job repository.

It contains a transaction per line, made up of a username, the user id, the date of the tran
