sale object in bus terminal project

[yekta68]

hi all

I work on bus terminal project.This project is for online bus ticket reservation or purchase it.

Is it necessary to have all of these classes:reservation,sale and ticket?
i feel reservation class is enough.please guide me about this problem and sale object for this purpose.

the answer is usually "it depends". however I would say in this case it's undoubtedly "no" a domain consisting of a single object doesn't have value.

you will have users who purchase a ticket for a trip on a bus. there are 4 entities right there (user, ticket, trip, bus). There will probably be more entities and definitely services as the process is discovered.

I recommend reading Domain Driven Design by Eric Evans to get a better feel of how you can design the code around the business problem.
