GumoCache

DASCache

TestCache

In the elements of Hibernate architecture is a factory of session and client of ConnectionProvider,It holds second level cache (optional) of data?

ConnectionProvider

Session

SessionFactory

Transaction

Which of the following are most common configuration methods of Hibernate Configuation

Mapping files

Web.config

Which of the following is FALSE about Session in hibernate?

Session is a light weight non-threadsafe object.

You can share the session between threads.

Session represents a single unit-of-work with the database

Session is the primary interface for the persistence service

There are core interfaces are used in just about every Hibernate application. Using these interfaces, you can store and retrieve persistent objects and control transactions? A. Configuration interface B. Session interface C. Query and Criteria interfaces D. User Interface E. Configuration interface

A, B, D

A, B, C, E

A, B, C, D, E

Which of the following is not a Session method?

Session.save()

Session.remove()

Session.persist()

D. Session.load()

Which of the following is NOT a best practice for defining your Hibernate persistent classes?

You must have a default no-argument constructor for your persistent classes and there should be getXXX() (i.e accessor/getter) and setXXX( i.e. mutator/setter) methods for all your persistable instance variables.

You should implement the equals() and hashCode() methods based on your business key and it is important not to use the id field in your equals() and hashCode() definition if the id field is a surrogate key (i.e. Hibernate managed identifier). This is because the Hibernate only generates and sets the field when saving the object.

It is recommended to implement the Serializable interface. This is potentially useful if you want to migrate around a multi-processor cluster.

The persistent class should be final because if it is final then lazy loading can be used by creating proxy objects.
