Hibernateibernate 33.0.0 )N3UPPORT1UALITY /RACLE "%! )"- HHibernateibernate 33.0.0 QUALITY THE NUMBER ONE SUPPORT FROM MARKET LEADER. Working with both object-oriented software and relational databases can THE SOURCE. be cumbersome and time consuming in today’s enterprise environments. Moreover, development costs are signifi cantly higher due to a paradigm mismatch between how data is represented in objects versus relational databases. Many software developers and architects estimate that up to 30% of their code is needed to deal with this infrastructure concern. Hibernate is an object/relational mapping (ORM) solution for Java applications that directly addresses this challenge by providing the ability to map an object model’s data representation to a relational data model and its corresponding database schema. Hibernate is the most fl exible and powerful ORM solution on the market today. Hibernate not only takes care of the mapping from Java classes to database tables and from Java data types to SQL data types, but also provides data query and retrieval facilities that signifi cantly reduce development time. Hibernate’s design goal is to relieve the developer from 95% of common data persistence related programming tasks by eliminating the need for manual, hand-crafted data processing using SQL and JDBC.

  • Develop a Simple Web Application with Apache Wicket and Apache
    Develop a simple Web application with Apache Wicket and Apache Geronimo Combine Wicket, Geronimo, and Apache Derby to form an open source Java Web development platform Skill Level: Intermediate Robi Sen ([email protected]) Vice President Department 13 LLC 10 Jul 2007 Apache Wicket is an innovative Java™ Web application framework that was introduced a couple of years ago. It helps simplify Web application development by clearly separating the roles of developers and designers. It lets you remove logical code from the view layer, eliminating the need for JavaServer Pages (JSP), providing a simple plain old Java object (POJO)-centric mode of development, and removing much of the need for XML and other configuration file formats. In this tutorial, learn how to set up your system to develop a simple Web application with Wicket, using Apache Geronimo as your application server and Apache Derby as the embedded database. Section 1. Before you start This tutorial is designed for developers who have found Java frameworks, such as Struts, lacking in needed functionality. If you're interested in developing Web applications in a more object-oriented manner, where the view is clearly separated from logic and there's minimal configuration and mapping, then Wicket is for you! This tutorial walks you through the basics of how Wicket works, while using Apache Geronimo to set up a Java Platform, Enterprise Edition (Java EE) server, Web server, and embedded database in just minutes. Combining Wicket with Geronimo lets you develop data-driven, scalable Web applications using software that's all open source.

In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient
