In this issue...

In this issue, we have a detailed article on Introduction to Java Persistence with Hibernate.

Abstract:JDBC is Java's solution for encapsulating the DBMS from the application code. However, using it requires developers to write SQL queries and exposes the data model to the application code. JDO is an effort to fully abstract and encapsulate the database from the application code and it realizes that through byte code enhancement. One alternate solution that is gaining popularity is Hibernate. In this article we present an introduction to the Hibernate open source persistence framework using a simple example.

Quiz from the past issue

By default, in .NET, what will be the result of evaluating the expression a/b, if b is assigned a value of 0?

Answer!

This quiz received an overwhelming number of responses (some correct and some not). The name of each one who responded has been entered for the year end drawing. The first and (almost) correct response came from Vijay! If the operands ‘a’ or ‘b’ is a Double or a Single, then it returns INFINITY. Otherwise it throws a DivideByZeroException exception.
