1. hibernate is ORM wich maps POJO using xml
file to access and create data form hatro database.
but in jdbc developers has to write code to map
object model data to rdbms and it access.
2. jdbc using SQL to access database developer has to
effective way to access the database.but hibernate
provides HQL wich powerful and includes all feature
of SQL and supports ploymorphic query.
3. Hibernate data transaction is fast due to work is
perform due container mean its xml file mostly but
JDBC has slow transaction.

Answer / mukundan
Hibernate is one level above JDBC in the sense that Hiberate
internally uses JDBC. Hence a direct comparison may not be
effecient. Still...
Hibernate is Object based mapping (ORM). JDBC concerns more
of RDB meta data mapped to the members of the java objects
i.e. POJO.
Data sent and results returned from RDB loaded back into
Domain (POJO) objects are taken care internally by
Hibernate. In JDBC loading the returned data from RDB into
java objects to be done externally, by developer.
Hibernate caches data at Level 1 and supports optional Level
2 caching through third party software (ehcache,
TreeCache/JBoss cache etc.) Caching is totally external to
JDBC.
Hibernate supports HQL which is again more Java Object
based. JDBC supports only SQL and relating and loading Java
objects should be done externally by developer.
Hibernate supports lazy loading of objects which JDBC
doesn't support.
RDB Table dependency and integrity in Hibernate is supported
through Object relationships. It is external to JDBC.
Through Object relationship (defined in XML) the entire RDB
DDL could be generated. This is out of scope in JDBC.

JDBC stands for Java Database Connectivity allows
developers to connect, query and update a database using
the Structured Query Language. JDBC API standard provides
Java developers to interact with different RDBMS and access
table data through Java application without learning RDBMS
details and using Database Specific JDBC Drivers.
Hibernate is an Object-Relational Mapping (ORM) solution
for JAVA. It is a powerful, high performance
object/relational persistence and query service. It allows
us to develop persistent classes following object-oriented
idiom – including association, inheritance and polymorphism.

Answer / sugunakarareddy
Hibernate is object relational mapping. which maps the pojos
using xml fiels. to access and create data from hetro
database. in jdbc we will a code for mapping to object model
data to relational database. access data.
jdbc support to sql only but in hibernate have hql is there.
all sql features are support to hql. but hql support
polymohisam query.
hibernate transaction performance is very fast compare jdbc
transcation.

What is java soft framework?
how to use CallableStatement? specially how to use their index given ..
Statement, PrepareStatement and Callable all these are interfaces. Thought it is a interface how come we are creating objects and calling methods("preparestatement()") in it. In which class this method is defined. Please let me know. Thanks in advance. example: PreparedStatement pre = con.prepareStatement( "UPDATE COFFEES SET SALES = ? WHERE COF_NAME LIKE ?");

code to insert values/rows into oracle database from a java swing textfield when a button is pressed(using preparedstatements)
Hi my doubt is that preparedStatement is a interface means which has no implemenation.plz go thru the code below String sql = "SELECT * FROM movies WHERE year_made = ?"; prest = con.prepareStatement(sql); prest.setInt(1,2002); ResultSet rs1 = prest.executeQuery(); Now setInt and executeQuery how it works since it is interface it does not have implementation how it works, how executeQuery returns result from database as executequery method has no implementation even in Statement interface.
