The Java Persistence API (JPA) is an object relational mapping API. Object relational mapping tools help us automate mapping Java objects to relational database tables. Earlier versions of J2EE used Entity Beans as the standard approach for object relational mapping. Entity Beans attempted to keep the data in memory always synchronized with database data, a good idea in theory, however, in practice this feature resulted in poorly performing applications.
Several object relational mapping APIs were developed to overcome the limitations of Entity Beans, such as Hibernate, iBatis, Cayenne, and Toplink among others.
With Java EE 5, Entity Beans were deprecated in favor of JPA. JPA took ideas from several object relational mapping tools and incorporated them into the standard. As we will see in this article by David Heffelfinger, NetBeans has several features that make development with JPA a breeze.Read Interacting with Databases through the Java Persistence API in full
Joomla!, a very popular content management system (CMS) is as you may know an easy-to-deploy-and-use content management system. This ease of use has lent itself to rapid growth of both the CMS and extensions for it. You can install it on almost any host, running Linux or Windows. This highly versatile software has found itself in such lofty places as large corporate web portals, and humble places such as the simple blog.
Joomla! itself is inherently safe, but misconfigurations of the CMS, vulnerable components, hosts that are poorly configured, and weak passwords can all contribute to the downfall of your site. Hence, it's always better to ensure the security of your site.

Tables got a bad review in accessibility circles, because they used to create complex visual layouts. This was due to the limitations in the support for presentational specifications like CSS and using tables for layout was a hack—that worked in the real world—when you wanted to position something in a precise part of the web page.
Tables were designed to present data of all shapes and sizes, and that is really what they should be used for.
This article by Joshue O Connor, shows how to build a simple table using Joomla! and the features contained within the WYSIWYG editors that can make the table more accessible.Read Creating Accessible Tables in Joomla! in full
