Payroll, Benefit and Compensation

(1) I am very new to Schema, Rules and Time Evaluation. Please can anyone explain to me how to use a rule given by company(e.g overtime 1.5hr) in Time Evaluation/Schema. In a simple word, how to write schema and why I need the schema and Time Evaluation. A simple step by step process of schema and Time evaluation will help. That will get me started.

(2) What do I need to know to enable me to configured, implement and support BENEFITS AND COMPENSATION?

Sorry for the inconvniences.

Regards
