Developing with Apache Derby -- Hitting the Trifecta: Database development with Apache Derby, Part 4
The Apache Derby software provides a powerful, open source database that can be used as a persistent store for a wide range of database applications. One of the main reasons for this popularity is Apache Derby's query support, which lets you selectively extract columns from specific rows across one or more tables that satisfy some Boolean condition. Learn about Apache Derby's query capabilities and how to use the SELECT statement to perform complex queries.

Use Apache Derby in your OpenLaszlo applications, Part 2: Storing and embedding data
Since OpenLaszlo's open source announcement, many developers have been using OpenLaszlo to create user-friendly rich Internet applications. Many of these applications require a database solution to have dynamic data fed to them. Because OpenLaszlo runs on Apache Tomcat by default, which supports JavaServer Pages (JSP) and servlets (Java), Apache Derby is an excellent database to use because it can be embedded in such applications and because Derby is written in pure Java code. In this tutorial, you'll build a management interface to the online shopping console created in Part 1. You'll also allow orders to be written to the database and enable management to edit, delete, and add new items to the database via the OpenLaszlo user interface (UI).

Use Apache Derby in your OpenLaszlo applications, Part 1: Supplying data using Derby
Since OpenLaszlo's open source announcement, many developers have been using OpenLaszlo to create user-friendly, rich Internet applications. Many of these applications require a database solution to have dynamic data fed to them. Because OpenLaszlo runs on Apache Tomcat by default, which in turn supports JavaServer Pages (JSP) and servlets (Java technology), Apache Derby is an excellent database to use. It can be embedded in such applications, and Derby is written in pure Java code. This tutorial uses an example of an online grocery store to illustrate the power of using OpenLaszlo with Apache Derby.

Apache Derby resources from the Web services perspective, Part 3: Manage Apache Derby using Web Services Distributed Management
So far in this three-part tutorial series about the concept of WS-resources and the Web Services Resource Framework (WSRF), you've created a Person resource and learned how to use WS-Notifications with it. This final installment shows you how to look at WS-Resources from a different perspective -- that of a tangible item rather than a set of information. You'll create a Web service to control the Apache Derby database you've been using throughout this project as well as the client that treats Derby as a WS-Resource.

Real-world Apache Derby: Who needs Ajax, anyway?
Asynchronous JavaScript + XML (Ajax) is a dynamite technique for greatly enhancing the user experience on the Web. But it pays to remember that it's only necessary because of the distance between the information source and the browser. Shorten that distance, and much of the need for Ajax goes away. This tutorial -- the second in this series on Apache Derby database use -- offers an alternate technique, one that allows reuse across several different environments.

Tuning LAMP systems, Part 2: Optimizing Apache and PHP
Applications using the LAMP (Linux, Apache, MySQL, PHP/Perl) architecture
are constantly being developed and deployed. But often the server administrator has
little control over the application itself because it's written by someone else.
This series of three articles discusses many of the server configuration items that
can make or break an application's performance. This second article focuses on steps
you can take to optimize Apache and PHP.

Two ways to build Apache Derby database applications in JRuby
JRuby is an implementation of the Ruby programming language that runs in the Java Virtual Machine (JVM). This tutorial demonstrates how to install and configure JRuby to connect to the Apache Derby database. As Ruby and Ruby on Rails become more popular, JRuby becomes an interesting technology to leverage the portability, security, and class libraries of the JVM while using Ruby features like simple syntax and closures. If you're writing a small application that needs a relational database, or you want to be able to ship a database with your product, then the Derby database is an excellent choice for a persistence mechanism. This tutorial shows you two methods of connecting to and building Derby database applications from JRuby.

Use Apache Derby to develop Eclipse plug-ins
Get a demonstration on how to use resource indexing with the Apache Derby database to develop Eclipse plug-ins. The Derby database embedded in Eclipse allows you to create an SQL database on the client side with no security issues or network problems, such as an unstable connection or high latency. An SQL database and the JDBC API provide an easy way to store information and quickly search previously stored data.

Introduction to Apache Maven 2
Modern software projects are no longer solely monolithic creations of single local project teams. With the increased availability of robust, enterprise-grade open source components, today's software projects require dynamic collaboration among project teams and often depend on a mix of globally created and maintained components. Now in its second generation, the Apache Maven build tool -- unlike legacy build tools created before the Internet-enabled era of global software development -- was designed from the ground up to take on these modern challenges. This tutorial gets you started with Maven 2.

Get a head start with JDBC 4.0 using Apache Derby
At the time of this writing, the Java Database Connectivity (JDBC) 4.0 specification is expected to be released from beta testing. It offers developers several enhancements to speed development and create a more object-oriented paradigm with regard to accessing and manipulating data stores. This specification relies heavily on existing technologies, such as Generics, the Metadata Facility, and JDBC RowSet. This tutorial demonstrates some of the new functions of the JDBC 4.0 specification in conjunction with the Apache Derby database.

Back to basics: Scripting Apache Derby's ij tool
Everybody's building Web applications these days. But what if you just want a little bit of data? Do you really need to go to the trouble of creating a whole application? Doesn't Derby provide a tool for that? Well, of course it does. Derby's main command line tool, ij, is designed for just that: manipulating and retrieving the data in the database from the command line. But ij is more than just a place to enter select statements. It provides a fairly comprehensive suite of tools and commands, such as the use and manipulation of cursors. This article explains the use of ij's advanced scripting capabilities. You may never go back to a Web application again.

Deploying Django applications to a production server
Django is a Python-based open source Web application framework that
focuses on making the process of creating database-driven Web sites and Web
applications easier. Getting started with developing Django applications is
simple, as a development Web server is included with the framework. However,
this server is not suitable for use in a production environment, so further
steps are required to deploy your Django application to the Web. In
this article, you will learn about the Django framework and how to install it
on your local machine. Discover how a Django application is made and
about the automatic administration interface created for your application. You
will then find out how to deploy your Django application to the Web on a
server running Apache and mod_python. Finally, learn how Django
applications can and should be scaled as your application's requirements
grow.
