Hi Venkat,
keep in mind use session beans for the verbs or actions (booking, searching, receiving and also "service") and entity beans for the nouns (date, ticket,...).
a) You may use a session bean DatingService, a DAO for serching process and an entity bean for the date.
b) BookingService-session bean, Ticket-entity
c) SearchService-session bean, DAO for the database search. If you only need a read only functionality you don't need the entity bean services.
d) I don't understand how it should work. It may be a fuzzy search. So it's like c)
Regards
Torsten
