c# - Choosing design patterns for basic classes -


i new design patterns , have read substanitial information (probably much) , think may trying on pattern solution.

i have 2 concepts model:

customer - types of customers defined , quite fixed (company, personel, sole trader...). various functionality arise depending on type of customer.

users - users classified either internal/external , if internal role perform hierachy , privileges allocated on role.

i going use decorator class , implement business entity objects processing rules inline best practices or on complicating , standalone class , sub class business logic ok?
