I have a set of questions pertinent to the architecture design for an application.
1.If any customer comes up with an application development what are all the factors taken into consideration in proposing an architecture design for developing the application?
2.What are the types of
J2EE architectures available?
Even in the case of Sun's Petstore Architecture(with clientTier,WebTier and EJBTier),What are the advantages in building the application accross three tiers?There are so many books explaining these features, but i find it intangible.It would be great if anyone could give me a practical explanation.
