In this exercise you will produce a single list of updates to customers' Cable TV packages. Customers can update their packages both through a Customer Care system and in shops. You will bring all these updates together into a single list.

…\inputData\ChannelPackages\CustomerCareUpdates\CustomerCareUpdates.txt

A file containing details of shop updates can be found in the input files, at:
…\inputData\ChannelPackages\ShopUpdates\ShopUpdates.txt
