Hibernate
Frameworks:
Hibernate basically a ORM tool. ORM
means object relation mapping.
Why do we use ORM tool:
If we don’t want to create my application
dependent on the database.We use Hibernate. In Hibernate we
have to create one file named as Hibernate Configuration file. In this file we mention which
database
we want to connect with our application & provide username and password of
that database.
Suppose my application is currently
working on MySql and i want to switch database from MySql to Oracle.
By using Hibernate You don’t need to
change any code. You just change the database name username and password in
the configuration file of Hibernate. Hibernate will automatically connected you
to Oracle by compiling once.
It was started in 2001 by Gavin King as
an alternative to EJB2 style entity bean. The stable release of Hibernate till
July 16, 2014, is Hibernate 4.3.6.
Framework is basically come in demand
because of fewer burdens faced by developers. A strut is the MVC framework. MVC
means Model-View-Controller.
The struts framework was initially
created by Craig McClanahan and donated to Apache Foundation in May,
2000 and Struts 1.0 was released in June 2001.Now a Days Struts2 in demand.
Firstly MVC: Model-View-Controller
Controller:
Controller is your xml file which is to be read by server for the mapping of
the incoming request to which page or on which servlet.
View:
View is the web-page which is shown to
Clients or o/p interacting.
Model: Mode
is the business logic.
Struts give us the pattern to place
right code at right place. Struts have own directory structure, if you want to
make MVC application by using Struts then you have to follow the Directory
structure of struts.
