Answer Posted / jaikant
in model 1 ,either Servlets or JSP handles all the
responsibilities for request.like processing the
data,validating the data, handling the business and data
access logic.
model 1 can be use when your application is small.
application can't have multiple interfaces(or views) for
same business logic.
Model 2 breaks your application in three parts
i)Controller: performs request processing,data validation
and works as controller between model and view.so there is
no direct interaction between model and view.
ii)model: it is core of the application.it is house of
business logic and data access code.model defines what
application does.we can subdivide model in 2 sub layer(data
access layer and business logic layer).
iii)view:it is place where presentation code reside.it is
the place for getting input and displaying data that is
generated by model layer.
