Java Hibernate Tutorial
Hibernate is an ORM tool. Hibernate is a
solution for object-relational mapping and a persistence management
layer. For example a java application is used to save data of an
object to a database. Hibernate provides a solution for this
persistence by mapping database tables to a class. The database data
is copied to the object. The copying the data as objects and vice
versa is known as object-relational mapping. A query that uses
select statement and its operations of fetching tuples is done by a
simple query object. And being an object, the same object can be
utilized several times, which reduces the ‘query defining time’.
Usage of simple java classes [ Plain Old Java Objects ] makes this
task simple instead of using entity beans / JDBC calls.
- Hibernate is a powerful, high performance object/relational
persistence and query service.
- Hibernate allows development of persistent classes following
object-oriented idiom that includes association, inheritance,
polymorphism, composition, and collections.
- Hibernate allows expressing queries in its own portable SQL
extension (HQL), as well as in native SQL, or with an
object-oriented Criteria and Example API.

C# (pronounced "C-sharp") is an object-oriented programming language from Microsoft that aims to combine the computing power of C++ with the programming ease of Visual Basic. C# is based on C++ and contains features similar to those of Java.
C# is designed to work with Microsoft's .Net
platform. Microsoft's aim is to facilitate the exchange of information
and services over the Web, and to enable developers to build highly
portable applications. C# simplifies programming through its use of
Extensible Markup Language and Simple Object Access Protocol (SOAP) which allow access to a programming object or method
without requiring the programmer to write additional code for each
step. Because programmers can build on existing code, rather than
repeatedly duplicating it, C# is expected to make it faster and less
expensive to get new products and services to market.

A database software is a type of computer program that is designed to
handle lots of data, but to store them in such a way
that finding (and thus retrieving) any snippet of data is more efficient
than it would have been if you simply dumped them
willy nilly all over the place. With such database software, if you
(say) keep a list of customers and their shipping addresses,
entering and retrieving information about your one millionth customer
will not take much longer (if at all) than entering and retrieving
information about your 1st customer.
Database programs have many different methods for storing and retrieving data, as well as for organising the stored data on
the computer. One popular way for accessing data, both to store and to retrieve it, is to use a computer language called
"SQL" (often pronounced as "sequel"). SQL was specially designed for database access.
There are many databases that support the use of
SQL to access their data, among them MySQL and PostgreSQL. In other words, MySQL is just a type of database, one of many. The
same goes for PostgreSQL. These two databases are commonly used by programs that run on websites.if you are a programmer, intending to write a computer program that actually accesses MySQL or some other SQL
database, then you will need to learn SQL (as well as a programming language).

Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a metered service over a network (typically the Internet).
Cloud computing is a marketing term for technologies that provide
computation, software, data access, and storage services that do not
require end-user knowledge of the physical location and configuration of
the system that delivers the services. |
