Batch Apex Class Information

Question

In our Sandbox Organization Apex Classes are written in year 2011. Please find below images and Apex Classes information and let me know about what is exactly they do in our organization with apex code.

Below is available Apex Classes Information.

Below is Schedule Apex Class “SubmitCheckSchedulableClass” Information

Above mentioned is Batch Class and Schedule Class in our Org. Please let me know information about above Batch and Schedule Class.

Thanks, Manu

Answer 1

This batch class integrate with an external system probably it is Telerx. It submit some check request and according to response Case record created in organisation also used object Jobs__c to get exact information about the code.

Once the check submitted successfully using the web-service it update the Webservice_Call_Result__c result and create task if there is any error some other action need to be done.

I hope this would make sense to you. I never logged in to your org.
