This is not a problem as long as the jobs are not sharing the same files, db-tables, or index spaces. If they do, this service should be implemented using partitioned data. We will create the application having the following 2 jobs -  1st Job: Reads the P roduct information from the database and after processing will give the rating to the project. 2nd Job: Reads the Invoice the information the database and update back to the database.  We are not focusing on the business logic here but the processing of data using multiple jobs.
